With what was made (heap type and flags, size, format, flags) and the game code that asked, at
most 40 times. Small buffers and textures took 120 to 170 ms each, two threads at the same moment,
which showed the 5 s stall was the GPU or driver held up by something outside the game, not the
size of what the game made.
The renderer gives each frame 131,072 shader-visible descriptors past a persistent 120,000, in
heaps of 333,333. Dense custom maps (the Los Santos City sublevels, San Andreas) draw more than
that in a frame, and the renderer wrote past the end of the heap: shaders read garbage
descriptors, which faulted or hung the GPU (page faults at nonsense addresses, in draws, texture
fetches and ray tracing alike). ReSkate now patches the device setup at boot so each heap is
D3D12's 1,000,000 and a frame may use 524,288; heaps are 644,288 descriptors. LS-B2, LS-B3 and
San Andreas (210,000 a frame at its peak) now hold.
Also in this change:
- Memory: perf memory owners/heap/gpu/report, a ledger of who commits the game's RAM; the
render-resource pool no longer allocates its 115 MB twice; the EadpErrorsData arena is
capped at 32 MiB (EA's error reporting is blocked anyway).
- Crash reports: tagged with the map, destination, graphics card and driver version (protocol
v3), so Sentry can group GPU hangs by map and card.
- GPU diagnostics (--gpu-diagnostics): a fuller DRED report, the device-removal and video
memory watches, a large-draw watch, a record of which game code made and freed each GPU heap
and resource, checks of every GPU address bound, and a meter of each descriptor heap's use.
- World pools: peak use of entity pages, render instances and spatial blocks in the log.
- dingosdk_mod_mesh_check: checks every MeshSet a mod ships against its geometry; the MeshSet
reader now knows static meshes' layout.
