This pre-release focuses on frame delivery and compatibility. It may still
fail to activate, show artifacts, freeze or crash.
What's new
- SteamVR presenter pacing and buffering changes targeting dropped synthetic
frames under heavy GPU load, including high-resolution MSFS 2024 setups. - D3D11 context protection and support for optional OpenXR frame-info pointers,
addressing compatibility problems reported with UEVR and Luke Ross mods. - Resource-lifetime fixes for queued frames when spaces or swapchains are
destroyed, including recenter and cleanup paths. - Consistent internal build identity across the DLL, tray and runtime cache.
Thanks to djules75 for
PR #3 and headset testing.
Optical-flow algorithms and the FPS overlay are unchanged from V066.
Before updating
Close the game and previous OFXR tray, extract the complete archive, then run
the new tray and arm it before starting the game. Run the game without
administrator privileges.
22/22 automated tests pass, but compatibility is not universal. Windows 10
no-load/no-log reports and the reported UEVR D3D12 crash remain unresolved.
See the integration notes
for validation limits.
Some FPS counters measure application frames before OFXR and may show roughly
half its output. OFXR's own counter measures accepted OpenXR submissions, not
physical headset scanout.
Please report working and non-working games through
GitHub Issues or the
Flat2VR Modding Discord, with an OFXR flight log
when available. Reports without a log are welcome too.
