A big release: Star Citizen support and Hybrid mode. OFXR now runs in
Star Citizen with Easy Anti-Cheat, and in games that use DLSS it can use the
game's own motion information for cleaner generated frames. It also brings
many fixes for MSFS 2024, Virtual Desktop and Pimax OpenXR.
🛠️ Not working, or not feeling smoother?
➡️ Read the troubleshooting guide first
It checks in one step whether OFXR is running in your game, then lists the
usual causes and fixes: OpenVR games, running as administrator, the game's
frame rate, frame smoothing in your VR software, and running out of VRAM.
What's new
Star Citizen: works with Easy Anti-Cheat, smooth in 2X and 3X
OFXR's files are now digitally signed, so Easy Anti-Cheat lets OFXR load in
Star Citizen. The world no longer wobbles when you move your head,
generated frames now reach the headset in 2X, and 3X holds a steady rhythm;
the wobble fix also applies to other Vulkan games.
Caution
OFXR is an independent project, not endorsed by Cloud Imperium Games or
Easy Anti-Cheat. Using it with an anti-cheat protected game is at your own
risk: we accept no responsibility for any account action, ban or other
consequence. Check the game's terms of service before you play.
New: Hybrid mode for DLSS games
Inspired by Eliott's and tig3rmast3r's
work, Hybrid (in the tray, off by default) combines the motion the game
calculates for DLSS with OFXR's optical flow, so moving objects keep their
shape with less warping, for some extra GPU time. It works in D3D12, D3D11 and Vulkan games,
including UEVR games, MSFS 2024 with foveated rendering and Luke Ross's
R.E.A.L. VR mods (compatibility guide).
Hybrid enhancement: no ghost behind fast-moving objects
The background revealed behind a fast-moving object no longer shows a ghost
of that object.
Hybrid enhancement: depth search
Hybrid: depth search (in the tray, off by default) uses the game's depth
to keep thin nearby objects, such as cockpit frames and railings, from
breaking up. It adds GPU time on top of Hybrid's, more at high headset
resolutions: turn it off if your frame rate drops.
HUD and markers no longer doubled
In UEVR games, HUD elements and quest markers no longer appear twice when you
turn your head. They now move smoothly with the generated frames.
Change settings while you play
The Frame Gen multiplier (2X or 3X), the optical flow and Hybrid now switch
in a running game, without restarting it.
Lighter default optical flow
FidelityFX is now the default optical flow: its quality is similar to
NVIDIA's, in particular with Hybrid on, and it costs less GPU time,
especially at high resolutions. A saved choice is kept.
More tray and overlay options
The FPS overlay shows whether Hybrid is working (HYBRID OK or HYBRID
KO), can show the latency OFXR adds, and comes in three sizes. Optical
flow can now run at 25% resolution, for the lightest GPU load.
Below the latency, the overlay now shows the multiplier in use, 2X or 3X
(Show multiplier in the overlay menu, on by default).
Linux with Proton
To our knowledge, OFXR has now run on Linux for the first time, in games
under Proton (issue 34).
A setup guide
explains how.
MSFS AutoFPS support
OFXR now shares its live state with other tools, so
MSFS AutoFPS knows when frame
generation is running and at which multiplier, and can adjust the
simulator's detail to keep your frame rate at its maximum.
Fixes and compatibility
- MSFS 2024, 3X on SteamVR: no longer gets stuck at a low frame rate
after a hiccup (issue 33). - Refresh rate changed during a session: motion is smooth again at the
new rate. - 3X after a camera change or a hiccup: the rhythm comes back on its own,
without a burst of uneven frames. - Virtual Desktop: recovers properly after a stall, and with Prefer
FPS over latency off, 2X gets back the 5 to 7 fps it had lost
(issue 36). - Elite Dangerous on Pimax OpenXR: no more stutter
(issue 40). - Star Citizen and MSFS 2024: pausing and resuming frame generation
works properly. - Skyrim VR with PrivateProfileRedirector: tray changes now reach the
running game.
Installing
Unzip anywhere and run OFXRBridgeTray.exe. It arms the bridge by itself.
Keep OFXRBridgeTray.exe and the ofxr folder together. If an earlier
version is armed, disarm it and close its tray first.
Please report results, working or not, on
GitHub Issues, with an OFXR
flight log where you can: enable Bridge flight recorder in the tray,
reproduce the problem, then use Open bridge logs. Logs are written under
%LOCALAPPDATA%\OFXR Bridge\RuntimeLayer\v551\.
