## Key points

- Experimental XeSS support brings Intel XMX processing to Proton games on Linux.
- Cyberpunk performance rose 29%, or 145% with frame generation.
- The project requires native Steam and has limited testing so far.

## Summary

An independent developer has released an experimental project that enables Intel’s XeSS upscaling and frame generation to use Intel GPU matrix units in Proton games on Linux. The approach could improve performance for Linux gamers with Intel Arc graphics while they wait for Intel’s planned official support.

Tests reported a 29% performance gain in Cyberpunk from XMX-based upscaling alone, rising to 145% when frame generation was added; Forza Horizon 6 saw a 16% gain from the upscaling change and a further increase with 3x frame generation. The project has run on an Intel G3 Extreme handheld chip and an Arc B580, but remains experimental. It requires the native Steam client; Flatpak Steam is not supported.
