Trying to stop the emulation in VR or S3D modes would result in a QT
dialog box popping up about whether you were sure you wanted to end
the emulation, but that caused no visible effect on the screen.
Now there's a dialog visible for it when emulating in those modes,
and it should correctly work for flat emulation and when pressing
the Stop button in the QT UI.
This fixes#11.
This fixes#14 and fixes#8 to my satisfaction. At least now, since
the game starts in the user's visual field, it is obvious that they
need to dismiss the Baiji UI to get to the game. This works like
everything else in the Steam Frame windowing environment.
Now the emulation never freezes, no matter how hard I focus off
of Baiji. May still be some problems here. But this is the closest
to correct it has been working yet.
This works toward #14, but is not entirely satisfactory as due to
some other previous fixes, when the Dolphin UI is displayed the
emulation window stops rendering. So that needs to be addressed.
The previous fix to fit them in their dialog box often unseated
the arrow from the widget it is trying to point at. With the user
so actively interacting with the widgets to get the help,
including having to hold the pointer steady to keep it where they
can read it (arguably a problem of its own), I don't think we need
to quite that aggressively point at the target widget.
Steam OS intepreted that as a resize of the window and recentered it.
This caused a lot of displeasing UI churn.
This still leaves the little chevrons pointed at the wrong places
sometimes but it is still a much better user experience.
In flat Vulkan mode, Steam Frame controller buttons can appear not to
reach the game while the system's laser-pointer mode still owns focus.
This is an easy mistake to make when starting a game from the headset.
After a successful boot, show an informational dialog for explicit Flat
Display (Vulkan) mode and for legacy configurations with OpenXR disabled.
The check happens after boot metadata and per-game VR settings are loaded,
so immersive VR and Stereo 3D Screen launches are not interrupted.
Add the requested reminder text and a Never See This Dialog Again
checkbox. Persist the opt-out in Main.Interface, and leave it unchecked by
default so the reminder appears for new users.
Immersive VR previously used the full runtime-reported left/right view
positions, with Units per Meter scaling both world geometry and the
per-eye offsets. That left no direct way to soften strong near-field
pop-out without also changing the apparent world scale.
Add Graphics.VR.StereoSeparation as a 0-200 percent setting, defaulting
to 100 percent. Scale each eye's positional offset around the average
eye center independently of shared head translation. At 100 percent the
projection is unchanged, 0 percent brings the virtual view positions
together toward mono, and values above 100 percent amplify stereo depth.
Units per Meter continues to set world scale and head-motion mapping.
Expose the setting in the global VR pane and per-game VR configuration,
include it in game VR override application/reset, and refresh cached
projection rows when it changes. Help text explains the scale/depth
tradeoff, possible near-field comfort benefit, and that Stereo 3D Screen
continues to use the existing Stereoscopic Depth control.
Add GFX_VR_REQUESTED_REFRESH_RATE setting (Auto/60/72/90/120 Hz). When a
non-zero rate is configured, call xrRequestDisplayRefreshRateFB after the
session begins so the runtime can switch the headset panel to a rate that
matches the game's frame rate (e.g. 60 Hz or 120 Hz for 60 fps Wii games,
instead of the default 72 Hz).
This should reduce judder caused by the compositor showing 60 fps content on
a 72 Hz display. The runtime may clamp the request to the nearest supported
rate; the result is logged.
UI exposed in VRPane and VRConfigWidget.
- Make Flat Screen and Stereo Screen checkboxes mutually exclusive in VRPane.
- Fix Vulkan Android stereo-screen submission to end the render pass and
submit the command buffer once before releasing both eye images, instead of
once per eye.
- Add IOpenXRSwapchain::GetEyeSwapchainHandle() and SubmitStereoFlatFrame(),
with per-backend overrides for Vulkan, D3D11, D3D12, and OGL.
- Add OpenXRManager::SubmitStereoQuadFrame() which builds two world-locked
XrCompositionLayerQuad layers with XR_EYE_VISIBILITY_LEFT/RIGHT and publishes
them through the pacing thread (or EndFrame on the legacy path).
- Extend PublishedXRFrame and FrameThreadLoop to submit the stereo quad pair.
- Add UI checkbox for Stereo Screen in VRPane and VRConfigWidget.
The game renders with classic SBS stereoscopy; left/right XFB layers are blit
into the corresponding OpenXR eye swapchains and shown as a 3D floating screen.
