Valve and CodeWeavers have released another fresh Proton Experimental build for testing upcoming features of the Proton compatibility layer for Linux gaming with Steam Play.
As the headline says, DLSS is coming to Proton! This was announced by NVIDIA only recently, which is quite exciting! Nice to see Proton itself already preparing everything needed, with a new NVIDIA driver (470) coming sometime soon.
Proton Experimental for June 2, 2021 pulls in these changes:
- Improved GPU device selection.
- Optionally support Nvidia's NVAPI GPU support library. It is disabled by default and can be enabled with `PROTON_ENABLE_NVAPI=1`.
- Prepare for Nvidia's upcoming DLSS support.
- Update to recent DXVK and vkd3d-proton.
- Better support for Xbox controllers in some Unity games.
- Fix Splitgate: Arena Warfare hangs and multiplayer performance issues.
