Update 24/07/23: GE-Proton 8-8 and GE-Proton 8-9 were released shortly after as hot-fixes to clean up some problems:
- This is a minor hotfix release that just syncs proton-wine and dxvk with upstream versions from today. A user complained they were seeing some odd CPU+GPU usage in 8-7 but was fine in today's proton-experimental. After testing with this build based on today's experimental they confirmed it was working here too.
- Hotfix: Apparently yesterdays build was missing the normal proton packaged Gecko and Mono (the file size was significantly smaller than usual). This build fixes that.
The compatibility layer GE-Proton version 8-7 has been released, bringing with it the return of AMD FSR support. This is more useful for desktop Linux (or desktop mode on Steam Deck), since the Steam Deck's main Gaming Mode has AMD FSR built into the performance options.
With support back it allows you to use AMD FSR 1 on top of any Vulkan game (or DXVK / VKD3D-Proton) running through GE-Proton. It's on by default and set to "balanced", you just need to set in-game resolution lower than your monitor and have it be in fullscreen mode. Showing the power of open source, the needed work to upgrade the AMD FSR patches was done by developer Ph42oN. You can change the settings using launch options noted on the GitHub (scroll down).
In addition to bringing back AMD FSR support here's the other changes:
- protonfix for Oceanhorn removed as it's no longer needed (thanks Iglu47)
- protonfixes added for Neptunia Re;Birth 1 & 2 (thanks NishiyamaPedro)
- proton-wine updated to latest git
- dxvk updated to latest git
- vkd3d-proton updated to latest git
- dxvk-nvapi updated to latest git
- upstream build changes pulled in
Reminder: GE-Proton is made by the community, it's completely separate to the official Proton from Valve.
