A free tool for Windows PCs with modern Nvidia GPUs adds eye-tracked foveated rendering to a huge number of SteamVR games.
Called PimaxMagic4All, the tool re-implements a feature Pimax ships in its Pimax Play software used to set up and adjust its headsets. As such, if you already own a Pimax headset, you don’t need it.
PimaxMagic4All should work with any SteamVR-compatible headset that exposes a low-level public API to retrieve eye tracking data, or which has third-party software that does so

The developer, by the way, is Matthieu Bucchianeri, a name you may recognize if you’re a regular UploadVR reader.
Bucchianeri is a very experienced developer, having worked on the PS4 and original PlayStation VR at Sony, Falcon 9 and Dragon at SpaceX, and HoloLens and Windows MR at Microsoft, where he currently works on Xbox. At Microsoft he contributed to OpenXR, and in his spare time he developed OpenXR Toolkit, VDXR (Virtual Desktop’s OpenXR runtime), and most recently Oasis, the native SteamVR driver that revived Windows MR headsets.
PimaxMagic4All has a simple graphical interface with three levels of foveated rendering: Maximum, Balanced, and Minimum. You can choose between prioritizing increasing performance, achieving a result where you shouldn’t notice the difference, or a balance of the two.
The tool can inject foveated rendering into any title that uses the DirectX 11 graphics API and OpenVR, Valve’s deprecated API for SteamVR. The game also needs to not have an anti-cheat system, since those will prevent code injection. And remember, you need to have an Nvidia graphics card, specifically a GTX 16 series or RTX card.

PimaxMagic4All is available on GitHub, where you’ll find both the source for the code added around Pimax’s core as well as compiled releases.
