Modified OpenVR DLL with AMD FidelityFX SuperResolution Upscaler
This modified openvr_api.dll allows you to apply FidelityFX SuperResolution upscaling to many SteamVR games, as long as they use D3D11.
To install, find the location of the openvr_api.dll in the game's installation folder:
- It might be located right next to the main executable (e.g. Skyrim, FO4).
- For Unity games, look in:
- For Unreal 4 games, look in:
Rename the existing
openvr_api.orig.dll, then extract both the
openvr_api.dll and the
openvr_mod.cfg from the archive to this directory. You should now edit the
openvr_mod.cfg to your liking and adjust the
sharpness parameters to your liking.
In case you want to uninstall the mod, simply remove the
openvr_api.dll file again and rename the original
openvr_api.orig.dll back to
In case you run into issues, the log file (
openvr_mod.log) may provide clues to what's going on.
This is a best-effort experiment and hack to bring this upscaling technique to VR games which do not support it natively. Please understand that the approach taken here cannot guarantee the optimal quality that FSR might, in theory, be capable of. AMD has specific recommendations where and how FSR should be placed in the render pipeline. Due to the nature of this generic hack, I cannot guarantee nor control that all of these recommendations are actually met for any particular game. Please do not judge the quality of FSR solely by this mod :)
I intend to keep working on the performance, quality and compatibility of this mod, so do check back occasionally.
- Half Life: Alyx and Star Wars: Squadrons do not work, because they don't like you replacing their openvr_dll.api.
- In rare cases, the rendering output may appear unnaturally dark when this mod is active. This is an issue with color space that I hope to be able to fix in a future release.
- Please report any other game that isn't working, assuming that it is a SteamVR game and uses D3D11 for rendering.
OpenVR is an API and runtime that allows access to VR hardware from multiple vendors without requiring that applications have specific knowledge of the hardware they are targeting. This repository is an SDK that contains the API and samples. The runtime is under SteamVR in Tools on Steam.
Documentation for the API is available on the GitHub Wiki
