+
+## [Unreleased]
+
+## [0.3.1] - 2026-09-20
+
+### Added
+
+- Each release carries a DEB, an RPM, and a pacman package beside the
+  AppImage, with a `.sha256` for every file. They install `/usr/bin/mocktail`
+  and conflict with each other and with upstream's `mocktail` package.
+  Nightcap is in no distribution repository or the AUR; the recipes under
+  `packaging/aur/nightcap{,-bin,-git}` build from this repository locally.
+- The AppStream metadata lists the Nightcap releases, so software centres
+  show the release history instead of upstream's.
+
+### Fixed
+
+- ETC2 texture decoding no longer blocks the thread that submits the frame.
+  Uploads decode on a background dispatcher and the submit carries a timeline
+  semaphore wait, so the GPU waits for the texture instead of the render
+  thread. Reading the application's compressed bytes moves to that dispatcher
+  too whenever they are already mapped. In Blade Ball the worst
+  `vkQueueSubmit` fell from 140ms to 1ms, its p99 from 4.9ms to 0.05ms, and
+  the total time spent in submits from 2534ms to 309ms. Frame interval is
+  unchanged: the remaining tail is the engine's own main-thread step. A device
+  without the `timelineSemaphore` feature decodes inline as before, as does a
+  submit whose `pNext` already sizes arrays by its semaphore counts.
+- The mouse pointer jumped when a right-click camera drag ended, and drifted
+  to the viewport edge during one. The input router inferred pointer capture
+  from SDL reporting zero absolute coordinates, which holds on X11 but not on
+  Wayland, where the reported position accumulates the relative deltas and
+  leaves the window. Motion, button, and wheel events now carry the window's
+  relative mouse mode. The right-click camera fallback also only captures
+  inside an experience, so the cursor stays free over the app surface.
+- Shutting the window down while an experience was starting or leaving could
+  free the pointer capture owner underneath the thread using it. Callers off
+  the SDL thread now hold a reference for the length of their call.
+- The TextBox caret did not move when a trailing space was typed in a
+  single-line field. The final cluster rect SDL_ttf reports stops at the last
+  inked glyph, so the laid-out width is used there instead. Wrapped layouts
+  keep the clamp, because their width is the widest line rather than the last.
+- Every TextBox keystroke re-ran `TTF_Init`, a fontconfig sort, six
+  `TTF_OpenFont` calls, and `TTF_Quit` on the render thread. The overlay holds
+  its opened fonts and reopens them only when the Roblox font or the point
+  size changes, keeping the current set when a reopen fails. Measured over 100
+  rasters, 1.59ms to 0.12ms per keystroke.
+- Staged ETC2 copies now carry an explicit host-write barrier. A queue
+  submission only makes host writes from before it visible to the device, and
+  an asynchronous decode writes after the submit, so without the barrier those
+  texels were not guaranteed to reach the copy that reads them.
+
+### Changed
+
+- `docs/PERFORMANCE.md` documents the GameMode settings to run with. A
+  `desiredgov=powersave` in `~/.config/gamemode.ini` overrides the packaged
+  `performance` default and clocks the CPU down for the whole session while
+  still reporting an active performance request.
+
+## [0.3.0] - 2026-09-18
+
+### Added
+
+- Custom Discord presence. `integrations.discord_rpc.text.title` replaces the
+  name in "Playing Nightcap", and `integrations.discord_rpc.images` sets the
+  large and small icons and their hover text. Text and image fields accept
+  `{place_name}`, `{place_icon}`, and `{creator_name}`. A field that expands
+  an empty placeholder is left out, and `text.state: ""` hides the state line.
+- The default Discord card now matches Sober: the title is "Roblox", the
+  details line is "Playing <experience>", the state is "by <creator>", and
+  the Roblox badge sits inside the experience icon. The creator comes from the
+  same Roblox games request that already fetches the experience name. With
+  `show_place_name: false` the creator is hidden too, so the card shows only
+  the title and timer.
+- `--profile <file>` writes a Chrome-format trace of the Vulkan adapter's
+  work: presents, GPU waits, submits, ETC2 texture decode, and pipeline and
+  shader creation. Open it in ui.perfetto.dev. `docs/BENCHMARKING.md`
+  describes the benchmark runs, and `scripts/summarize_profile_trace.py`
+  turns traces into a before and after table.
+
+### Fixed
+
+- Texture uploads stalled the frame they were submitted on. ETC2 batches
+  decoded on worker threads but were then resampled one upload at a time on
+  the submitting thread, which at the default 4x upscale is sixteen times the
+  decoded texels. Resampling now runs on the same worker pool, in two passes so
+  mip level 0 still resolves before the mips built from it. In a 70k-part
+  place the worst `vkQueueSubmit` fell from 167ms to 92ms.
+- Most ETC2 batches decoded on a single thread. Workers were created and
+  joined per batch, so the parallel floor had to cover that cost and sat at a
+  1024x1024 image; batches under it ran on the caller, which was 54% of all
+  decode time in a 70k-part place. Decode workers are now a persistent pool,
+  and the floor drops to a 128x128 image. Mean decode time in that place fell
+  from 8.2ms to 4.7ms, and 11.8ms before both texture fixes.
+- On CPUs with a wide core-speed spread, Feral GameMode pinned the process to
+  the few fastest cores, concentrating Roblox's worker pool onto them instead
+  of spreading it. With `performance.gamemode: auto`, a request that narrows
+  the CPU affinity is now released again, which releases the pin. Set
+  `pin_cores=no` in `~/.config/gamemode.ini` to keep GameMode without the
+  pinning, or `performance.gamemode: on` to accept it. See
+  `docs/PERFORMANCE.md`.
+- With `show_place_name: false`, Discord no longer shows the experience
+  thumbnail or its name on hover.
+- The host main thread no longer spins on the engine's message pump, which
+  cost about half a core and 146,000 empty calls a second. It now rests 100 µs
+  between polls: sleeping when the governor is `performance`, parking the
+  core with TPAUSE on CPUs that have it, spinning otherwise. With GameMode
+  setting the governor, process CPU in a 60k-part place fell from 216% to
+  107% at the same 120 fps. `MOCKTAIL_ENGINE_PUMP_REST` forces a mode; see
+  `docs/PERFORMANCE.md`.
+- ETC2 uploads with a `bufferRowLength` or `bufferImageHeight` larger than
+  the image read the padded rows as packed data and decoded garbage.
+- ETC2 resampling created and joined worker threads on every batch. It now
+  runs on the persistent decode pool.
+- A failed trace write left the profile writer thread waking every 250 ms
+  for the rest of the session. It now exits.
+- The `--profile` trace gains a `pump` slice for the engine's main-thread
+  step.
+
+## [0.2.0] - 2026-09-16
+
+### Added
+
+- FAQ covering Discord RPC, log locations, and VR, adapted from upstream.
+- `input.raw_mouse` in `config.yaml` sends mouse look deltas in the host's
+  own units. Turn it on when first-person aiming feels too slow or too fast
+  under fractional display scaling. Off by default.
+- Nightly AppImage builds, published as the `continuous` prerelease. They are
+  untested; use a tagged release for normal play.
+
+### Changed
+
+- Values in `fflags.json` now win over the performance preset instead of
+  stopping the launch. Startup prints each key it kept.
+- Discord Rich Presence uses Nightcap's own Discord application, so it shows
+  as "Playing Nightcap". Terms and privacy pages for it live on the
+  project site.
+- Discord Rich Presence is on by default. Set
+  `integrations.discord_rpc.enabled: false` to turn it off.
+- The AppImage build verifies its reduced dependency packages against digests
+  taken at build time, rather than a digest list kept in the repository.
+
+### Fixed
+
+- Mouse look keeps responding after a long turn. The tracked pointer position
+  could drift past the edge of the view, which swallowed every reversal until
+  the mouse travelled all the way back.
+- Nightcap no longer refuses to start with `cannot lock appStorage`. It
+  created its own credential directory using the process umask, then rejected
+  that directory for being group writable. Systems with a permissive umask,
+  such as `002`, failed on first run.
+
+## [0.1.0] - 2026-09-15
+
+First Nightcap release, forked from komaruworld/mocktail.
+
+### Added
+
+- ETC2 and EAC texture emulation on Vulkan, so games that use compressed
+  mobile textures render correctly on desktop GPUs. Decoding runs on worker
+  threads to avoid stutter.
+- PNG texture overrides in `~/.config/mocktail/textures`, keyed by upload
+  hash, with a dump mode to find the texture you want to replace.
+- Small textures are upscaled 4x by default. Set
+  `MOCKTAIL_SMALL_TEXTURE_UPSCALE=1` to turn it off.
+- AppImage and signed Flatpak builds on every release tag. The Flatpak repo
+  is published at https://coderdayton.github.io/nightcap/.
+- Roadmap in `docs/ROADMAP.md`.
+
+### Changed
+
+- Frames are presented as soon as they are ready instead of waiting in a
+  queue, which lowers input latency.
+- Roblox now sees the real host RAM and display size instead of a low-end
+  phone profile.
+- App ID is `io.github.CoderDayton.nightcap`, so Nightcap installs next to
+  upstream Mocktail. The binary and config paths keep the `mocktail` name.
+- New name, icon, and colors.
+- The desktop entry launches on Wayland and points at the installed binary.
+
+### Fixed
+
+- Servers no longer kick with error 319 shortly after joining.
+- The FMOD output-device bridge is optional, so the updater no longer fails
+  without it.
+- The AppImage build no longer fails on stale checksums for the slimmed
+  Arch packages.

+# FAQ

-[How do I change my FPS?](/FAQ.md#how-do-i-change-my-fps)
+## How do I turn Discord RPC off?

-### How do I change my FPS?
+RPC is on by default. It never signs in to Discord and never reads an
+account token. To turn it off, launch Nightcap once to create the config,
+then close it. Open `config.yaml`:

+- Native / AppImage: `~/.config/mocktail/config.yaml`
+- Flatpak: `~/.var/app/io.github.CoderDayton.nightcap/config/mocktail/config.yaml`

-Go to $HOME/.config/mocktail, there is a file called config.yaml (appears after opening for the first time mocktail)
+For native installs, a custom `$XDG_CONFIG_HOME` replaces `~/.config`.

+Set `enabled` to `false` under `integrations.discord_rpc`. If the block is
+missing, add it under the existing `integrations` section:

-<img width="460" height="241" alt="image" src="https://github.com/user-attachments/assets/b30b1fea-4937-4858-937a-3096a9e8b2ad" />
+```yaml
+integrations:
+  discord_rpc:
+    enabled: false
+```

+Save the file and restart Nightcap. Set `enabled` back to `true` to turn
+RPC on again.

-with your text editor of preference search for "graphics" 
+## Can Discord count Nightcap as Roblox play time or quests?

+No. Discord only credits play time and quests to games its own scanner
+detects, and Rich Presence never counts. On Linux the scanner only matches
+games with a Linux entry in Discord's list. Roblox has none, so no process
+name Nightcap could use would be detected. Only Roblox or Discord can change
+that.

-<img width="1022" height="619" alt="image" src="https://github.com/user-attachments/assets/f86791e9-7ac3-4d13-b81b-3cf9e3e64c3d" />
+## Where can I find logs for a bug report?

+Nightcap saves logs automatically. Reproduce the issue, close Nightcap, and
+attach `latest.log`:

-change the display value to your desired fps, also turn off vsync if you want more fps than your display supports
+- Native / AppImage: `~/.local/state/mocktail/logs/latest.log`
+- Flatpak: `~/.var/app/io.github.CoderDayton.nightcap/.local/state/mocktail/logs/latest.log`
+
+For native installs, a custom `$XDG_STATE_HOME` replaces `~/.local/state`.
+
+## Can I play in VR?
+
+VR is experimental and lives on upstream's `vr` branch, which does not
+include the Nightcap changes. Install the
+[build dependencies](README.md#building), then switch to that branch and
+build:
+
+```bash
+git remote add upstream https://github.com/komaruworld/mocktail.git
+git fetch upstream
+git switch -c vr upstream/vr
+git submodule update --init --recursive
+cmake -S . -B build -DCMAKE_BUILD_TYPE=Release -DMOCKTAIL_ENABLE_VR=ON
+cmake --build build -j4
+```

+## About this fork
+
+Nightcap is a fork of [komaruworld/mocktail](https://github.com/komaruworld/mocktail)
+with extra fixes for playing on a PC. The program and config paths keep the
+`mocktail` name so upstream fixes still apply cleanly. The app ID is
+`io.github.CoderDayton.nightcap`, so Nightcap and upstream can be installed
+side by side.
+
+- **Lower input lag.** Frames are shown as soon as they are ready instead of
+  waiting in a queue.
+- **Sharper textures.** Small textures are upscaled 4x by default, and you
+  can replace any texture with your own PNG in `~/.config/mocktail/textures`.
+  A ready-made crosshair is in [`textures/`](textures/README.md). Set
+  `MOCKTAIL_SMALL_TEXTURE_UPSCALE=1` to turn the upscale off.
+- **ETC2 textures on any GPU.** Games that use compressed mobile textures now
+  render correctly on desktop GPUs, without stutter.
+- **No more error 319 kicks.** Servers no longer drop you shortly after
+  joining.
+- **Correct device info.** Roblox sees your real RAM and screen size.
+- **Better desktop launcher.** Runs on Wayland and always finds the installed
+  binary.
+
+Everything else works the same as upstream. See the
+[roadmap](docs/ROADMAP.md) for what is coming next, the
+[changelog](CHANGELOG.md) for what each release changed,
+[performance](docs/PERFORMANCE.md) for CPU load, heat and the knobs that change
+them, and the [FAQ](FAQ.md) for Discord RPC, logs, and VR.

+# Benchmarking
+
+A pull request that claims a speedup shows before and after numbers taken
+the way this guide describes. Numbers from different machines are not
+compared with each other. Each run is compared with a run on the same
+machine.
+
+## Two layers, two tools
+
+Roblox measures its own work. Nightcap measures the layer between Roblox and
+your driver.
+
+| Layer | What it covers | Tool |
+| --- | --- | --- |
+| Roblox | Scripts, physics, rendering jobs, network | Roblox's stats overlays, Shift+F4 and Shift+F5 in game |
+| Nightcap | Vulkan adapter: present, swapchain and GPU waits, submits, ETC2 texture decode, pipeline and shader creation | `--profile` |
+
+A Nightcap change should move the `--profile` numbers. If it only moves the
+Roblox overlay numbers, say so in the pull request, since the cause is then
+less direct.
+
+## Recording a trace
+
+```sh
+mocktail --profile ~/nightcap-before.json
+```
+
+The Vulkan adapter writes a Chrome-format trace to that file, a few times a
+second. The file is valid JSON after every write, so a session that crashes
+or is killed still leaves a readable trace. Exit from the Roblox menu when you are done. Open the file
+in [ui.perfetto.dev](https://ui.perfetto.dev) or `chrome://tracing`.
+
+Expect about 130 bytes per event, around 15 MB per minute at 240 FPS.
+Profiling is off unless `--profile` is given, and `MOCKTAIL_PROFILE_TRACE`
+does the same thing as the flag.
+
+### What the trace contains
+
+Each slice is named after the call it times, on the thread that made it.
+
+| Category | Slices | Arguments |
+| --- | --- | --- |
+| `present` | `vkQueuePresentKHR`: the whole adapter present, including the text overlay | `result` |
+| `present` | `host present`: the host driver's present, nested inside the slice above | |
+| `wait` | `vkAcquireNextImageKHR`, `vkAcquireNextImage2KHR`, `vkWaitForFences`, `vkWaitSemaphores`, `vkWaitSemaphoresKHR`, `vkQueueWaitIdle`, `vkDeviceWaitIdle` | |
+| `submit` | `vkQueueSubmit`, `vkQueueSubmit2`, `vkQueueSubmit2KHR` | `submits` |
+| `texture` | `etc2 decode`: CPU decode of ETC2 textures. On a device with a timeline semaphore this runs on the decode dispatcher, not the submitting thread | `uploads`, `compressed_bytes`, `decoded_bytes` |
+| `texture` | `etc2 gather`: the part of an asynchronous upload that stays on the submitting thread. Absent when the decode ran inline | `uploads`, `compressed_bytes`, `decoded_bytes`, `ticket` |
+| `pipeline` | `vkCreateGraphicsPipelines`, `vkCreateComputePipelines` | `count`, `cache` (1 when a pipeline cache was passed), `result` |
+| `pipeline` | `vkCreateShaderModule` | `bytes`, `result` |
+| `pipeline` | `vkCreatePipelineCache` | `initial_bytes`, `result` |
+| `pump` | `nativeCallMessagesFromMainThread`: the engine's main-thread step, on the host main thread. Only calls of 20 µs or more are recorded; the empty polls between them are not. | |
+
+The `frame interval (ms)` counter is the time between successive adapter
+presents. `vkQueuePresentKHR` time minus `host present` time is the adapter's
+own cost per frame.
+
+## The benchmark runs
+
+Run every scenario before and after the change, on the same build type
+(`make build`), with the same `config.yaml`. Close other GPU-heavy apps.
+Record `graphics.frame_rate_limit` and `graphics.vsync` in the pull request,
+because a frame cap hides frame time gains.
+
+Record `~/.config/gamemode.ini` too, and do not change it between the before
+and after runs. `desiredgov` there decides the CPU governor for the whole
+session and therefore which engine pump mode is chosen, which moves process
+CPU by more than most changes under test. See
+[PERFORMANCE.md](PERFORMANCE.md).
+
+Frame interval p99 varies by 2 ms or more between identical runs, so a
+difference that size is not a result. Three runs per scenario is the minimum
+for any frame-time claim; slice totals for a specific subsystem are far less
+noisy and can be read from fewer.
+
+| Scenario | How to start | What to do | What it shows |
+| --- | --- | --- | --- |
+| Home screen, cold | `mocktail --profile home-cold.json` with an empty shader cache (below) | Wait 30 s on the home screen, exit | First-load stutter: `pipeline` and `texture` slices |
+| Tower of Hell | `mocktail --profile toh.json --launch-uri "roblox://experiences/start?placeId=1962086868"` | Stand still at spawn for 60 s, exit | Steady-state frame time on a light scene |
+| Murder Mystery 2 | `mocktail --profile mm2.json --launch-uri "roblox://experiences/start?placeId=142823291"` | Stay in the lobby for 60 s, exit | Frame time with many players and a busier scene |
+
+For the cold run, point the driver's shader cache at an empty directory, so
+your normal cache is left alone:
+
+```sh
+cache=$(mktemp -d)
+MESA_SHADER_CACHE_DIR="$cache" __GL_SHADER_DISK_CACHE_PATH="$cache" \
+  mocktail --profile home-cold.json
+```
+
+`MESA_SHADER_CACHE_DIR` applies to Mesa drivers (AMD, Intel) and
+`__GL_SHADER_DISK_CACHE_PATH` to the NVIDIA driver.
+
+Run each scenario three times and keep the median run, since one run can
+catch a background stall.
+
+## Comparing runs
+
+```sh
+scripts/summarize_profile_trace.py toh-before.json toh-after.json
+```
+
+This prints a Markdown table with one column per trace: frame count, frame
+interval mean, p50, p95, p99 and max, then count, total, mean, p99 and max
+for every slice name, largest total first. Paste the table into the pull
+request and attach both traces.
+
+For frame time, compare p95 and p99 as well as the mean. Stutter shows up in
+the tail first. For first-load work, compare the `total (ms)` rows of the
+`pipeline` and `texture` slices from the cold run.

+# Performance and CPU load
+
+What Nightcap does to your CPU and GPU, which knobs change it, and how to
+measure rather than guess.
+
+## GameMode core pinning
+
+Nightcap asks Feral GameMode for a performance session at startup
+(`performance.gamemode`, default `auto`). GameMode raises the CPU governor and
+the process priority, which helps.
+
+On a CPU with a wide spread of per-core maximum frequencies — Intel P-core and
+E-core parts, AMD parts with preferred cores — GameMode also pins the process
+to the fastest cores. On a 32-thread host that can mean 4 usable threads out of
+32. Roblox spreads its work across a worker pool, so the pin concentrates that
+pool onto a couple of physical cores instead of spreading it. Those cores sit
+near their boost ceiling and run hot while the rest of the chip idles.
+
+GameMode re-applies the pin roughly every 5 seconds, so widening the mask from
+inside the process does not hold. Releasing the request does release the pin.
+
+Under `auto`, Nightcap therefore checks its CPU affinity immediately after the
+request. If GameMode narrowed it, Nightcap ends the request and prints:
+
+```
+  [gamemode] released: it pinned this process to a subset of the CPUs, ...
+```
+
+The trade is that GameMode's governor and priority boost go with it. To keep
+those and lose only the pinning, turn pinning off for every game on the host.
+
+These are the settings to run with:
+
+```ini
+# ~/.config/gamemode.ini
+[general]
+desiredgov=performance
+
+[cpu]
+pin_cores=no
+park_cores=no
+```
+
+`desiredgov` is the one to check first. The packaged default in
+`/usr/share/gamemode/gamemode.ini` is already `performance`, but a value in
+your own file replaces it, and `desiredgov=powersave` there means GameMode
+clocks the CPU **down** for the whole session while still reporting
+`[gamemode] performance request active`. The symptoms are a low CPU clock
+under load, a GPU that never leaves its lower SM clocks, and the engine pump
+falling back to `tpause` — which costs about 70% of a core instead of 3%,
+because `sleep` is only chosen when the governor reads `performance`. On one
+13900K host, correcting `powersave` to `performance` took the process from
+177% CPU to 42% and the package from 70°C to 53-63°C, at the same frame rate.
+
+GameMode reads `$XDG_CONFIG_HOME`, `/usr/share/gamemode` and `/etc`, in that
+order. It does not read anything under Nightcap's own config directory, so this
+file has to live in one of those three places. The daemon reads it when it
+starts, so restart it after editing: `systemctl --user restart gamemoded`.
+
+Restarting the daemon drops the session of any game already running; relaunch
+the game for new settings to apply to it.
+
+`gamemoded` is D-Bus activated through
+`com.feralinteractive.GameMode.service`, so `systemctl --user stop gamemoded`
+does not hold — the next client request starts it again within seconds. To
+measure with GameMode genuinely off, mask it:
+
+```bash
+systemctl --user mask gamemoded     # and --unmask afterwards
+```
+
+The governor switch runs through polkit. Debian and Ubuntu only allow it for
+members of the `gamemode` group; without that, the daemon's journal shows
+`cpugovctl set performance: Not authorized` and the governor stays put while
+the session is otherwise active. Add yourself and log in again:
+
+```bash
+sudo usermod -aG gamemode "$USER"
+```
+
+Fedora and Arch allow any logged-in local user.
+
+Setting `performance.gamemode: on` accepts the pinning instead: `on` is an
+explicit request for GameMode, and Nightcap keeps the session whatever it does
+to the affinity. `off` never contacts the daemon.
+
+To see which CPUs the process may use:
+
+```bash
+pid=$(pgrep -x Main)
+for t in /proc/$pid/task/*; do taskset -pc "${t##*/}"; done
+```
+
+Two traps here. The engine process reports its name as `Main`, not
+`mocktail`; `pgrep -x mocktail` finds only the launcher, which sits near 0%
+CPU and tells you nothing. And `taskset -p` reads one thread, not the whole
+process, so a single call reports the main thread's mask and says nothing
+about the workers — which is where the game's load actually is.
+
+For the same reason, `ps -L -o psr=` shows which core each thread is running
+on right now, not which cores it is allowed on. On a hybrid CPU the scheduler
+preferring P-cores for runnable work is normal and is not a mask.
+
+## The main-thread pump
+
+Roblox posts its per-frame main-thread step at a time of its own choosing,
+and nothing signals the host when it does. The host main thread therefore
+polls `nativeCallMessagesFromMainThread`, and a post that waits more than a
+fraction of a millisecond costs a whole frame. Between polls the thread rests
+for 100 µs, and how it rests decides the CPU clock:
+
+| Mode | When | What it costs |
+| --- | --- | --- |
+| `sleep` | The governor is `performance`, which GameMode sets | The thread idles at about 3% of a core. The governor holds the clock. |
+| `tpause` | Otherwise, on a CPU with WAITPKG (Intel 12th gen and newer) | The core stays awake in a light C0 state. Frame rate holds; the OS books the time as busy, so the thread shows around 70% of a core, at lower power than a spin. |
+| `spin` | Otherwise | The core stays awake at full power. |
+
+Under a power-saving governor the CPU clocks a bursty core down unless some
+core stays awake, and Roblox's render thread then runs slower and drops
+frames. That is why `sleep` is not the default there. Startup prints the
+chosen mode:
+
+```
+  [main] engine pump rest: tpause (MOCKTAIL_ENGINE_PUMP_REST=sleep|tpause|spin)
+```
+
+`MOCKTAIL_ENGINE_PUMP_REST` forces a mode. `sleep` without the governor's help
+runs cooler for a few frames per second less; measure before keeping it.
+
+## Small texture upscaling
+
+`MOCKTAIL_SMALL_TEXTURE_UPSCALE` (default `4`) redraws ETC2 textures of 64px or
+smaller at N times their width and height. At the default that is 16 times the
+pixels per affected texture.
+
+The cost lands in two places. Decoding and resampling is CPU work on up to 8
+threads while textures load, which shows up as a burst rather than a steady
+load. The enlarged textures then stay in GPU memory for the session and cost
+extra sampling bandwidth on every frame that uses them.
+
+That decode does not run on the thread that submits the frame. On a device
+with a timeline semaphore, uploads decode on a background dispatcher and the
+submit carries a semaphore wait, so the GPU waits for the texture instead of
+the render thread. In the trace this is the `etc2 decode` slice on its own
+thread, with only a negligible `etc2 gather` left on the submitting one. A
+device without that feature decodes inline as before.
+
+Set it to `1` to turn upscaling off:
+
+```bash
+MOCKTAIL_SMALL_TEXTURE_UPSCALE=1 mocktail
+```
+
+## Frame rate and present mode
+
+`graphics.frame_rate_limit` (default `-1`) leaves Roblox's own in-game
+framerate cap in charge; Nightcap sets no `DFIntTaskSchedulerTargetFps`
+override. A fixed value forwards that number to the scheduler.
+
+`graphics.vsync` (default `auto`) selects the presentation mode. `auto` and
+`on` both pick the lowest-latency synchronized mode the driver offers, in
+order: `FIFO_LATEST_READY`, `MAILBOX`, `FIFO_RELAXED`, `FIFO`. The first two do
+not block the render thread on the display refresh, so the frame rate is
+governed by the in-game cap rather than by presentation. `off` selects
+`IMMEDIATE` and does not synchronize at all.
+
+If the frame rate is higher than your refresh rate, the extra frames are work
+you cannot see. Lower the in-game cap to your refresh rate first.
+
+## Measuring
+
+Shift+F4 in game shows Roblox's own scheduler jobs, with a millisecond cost and
+a percentage for each. It does not show Nightcap's threads — the Vulkan
+adapter, the ETC2 decode workers, the libc shim — so it is a reading on the
+game, not on the process.
+
+For the whole process:
+
+```bash
+top -H -p $(pgrep -x mocktail)      # per-thread CPU, sorted
+ps -L -o psr=,pcpu=,comm= -p $(pgrep -x mocktail)   # which core each thread is on
+nvidia-smi --query-gpu=utilization.gpu,temperature.gpu,power.draw --format=csv
+```
+
+A thread pinned near 100% while the frame rate is steady is a busy-wait. The
+one exception is the host main thread in `tpause` mode, which the OS reports
+as busy while the core is parked (see above). Load spread across many
+`RBX Worker` threads is the game's own scheduler, and its cost tracks the
+place you are in — part count, moving parts and joints all show in the
+Shift+F4 World section.
+

+ui.perfetto.dev. See [BENCHMARKING.md](BENCHMARKING.md).

+# Nightcap roadmap
+
+What Nightcap is working toward, in priority order. Items move to
+[Shipped](#shipped) when they land on `main`. Open an issue to propose a
+change to this list.
+
+## 1. Settings UI
+
+Nightcap is configured by editing `~/.config/mocktail/config.yaml`. Most
+people never open it, so they never find the FPS unlock or the vsync switch.
+
+Goal: a small GTK4 settings window, reachable from the app menu and from a
+`--settings` flag, that reads and writes the same `config.yaml`.
+
+- Graphics tab: backend, frame rate limit, vsync, small texture upscale.
+- Input tab: the `input.raw_mouse` toggle and controller options.
+- Advanced tab: FFlag overrides with a plain text editor for `fflags.json`.
+- Discord tab: every field in the `discord_rpc` block, so a friend can see
+  what you are playing and you can switch it all off in one click.
+- Changes apply on next launch. A restart button restarts Nightcap.
+
+Done when every option in `config/mocktail.example.yaml` that a player would
+touch can be set without a text editor.
+
+## 2. Controller button glyphs
+
+Upstream added Xbox and PlayStation gamepad support through SDL. Controllers
+already hot-plug and release their held inputs when unplugged. One rough edge
+is left.
+
+- Correct button glyphs for the connected pad. `SDL_GetGamepadType` is only
+  read for Xbox and PlayStation pads, so a Switch Pro, a GameCube pad, or any
+  generic pad SDL reports as `SDL_GAMEPAD_TYPE_STANDARD` reaches Roblox as
+  type 0 and draws generic glyphs. `SDL_GetRealGamepadType`, and the vendor
+  and product IDs, are available and unused.
+
+Done when a plugged-in pad shows its own buttons.
+
+## 3. First-load stutter
+
+The `--profile` trace now shows shader compiles and pipeline creation, so
+the stutter on first entering an experience can be measured.
+
+- Cut the stutter the trace shows, and prove it with a before and after
+  trace per [BENCHMARKING.md](BENCHMARKING.md).
+
+Done when entering a fresh experience no longer drops frames on shader
+compiles.
+
+## Shipped
+
+- Lower input latency: frames are presented as soon as they are ready.
+- Controllers hot-plug without a restart, and a pad that is unplugged mid-game
+  releases its held buttons and sticks instead of leaving them stuck.
+- Mouse look keeps responding after a long turn, instead of going dead until
+  the pointer travels back from past the screen edge.
+- Optional raw mouse input: `input.raw_mouse` in `config.yaml` sends look
+  deltas in host units, so fractional display scaling no longer changes
+  first-person sensitivity.
+- Small textures upscaled 4x by default, with PNG overrides in
+  `~/.config/mocktail/textures`.
+- ETC2 textures decoded on desktop GPUs without stutter.
+- No more error 319 kicks after joining a server.
+- Roblox sees the real host RAM and screen size.
+- Desktop launcher that works on Wayland and finds the installed binary.
+- Discord Rich Presence on by default, with the experience name, creator,
+  elapsed time, the experience icon with a Roblox badge, and a join button
+  when the server is public. See the [FAQ](../FAQ.md) to switch it off.
+- Custom Discord presence: title, details, state, and large and small icons
+  from `config.yaml`, with `{place_name}`, `{place_icon}`, and
+  `{creator_name}` placeholders.
+- `--profile` writes a Chrome-format trace of the Vulkan adapter's work,
+  including shader and pipeline creation, readable in `ui.perfetto.dev`.
+  [BENCHMARKING.md](BENCHMARKING.md) fixes the experiences to measure and
+  `scripts/summarize_profile_trace.py` builds the before and after table.
+- Texture uploads no longer stall the frame they land on: ETC2 decode and
+  resampling run on a persistent worker pool.
+- The host main thread rests between engine polls instead of spinning, and
+  GameMode's core pinning is released, so Roblox's workers spread across
+  every core. See [PERFORMANCE.md](PERFORMANCE.md).
+- Own app ID `io.github.CoderDayton.nightcap`, so Nightcap installs next to
+  upstream.
+- AppImage and signed Flatpak releases on every `v*` tag, with the Flatpak
+  repo on GitHub Pages.
+
+## Not planned
+
+- Replacing the `mocktail` binary and config names. Keeping them makes
+  upstream merges clean.
+- DEB, RPM, and AUR packages. Upstream ships those for unmodified Mocktail.
