Proton 6.13 GE-1 is out now with AMD FidelityFX Super Resolution, Resizable BAR

Proton GE, the community-made version of Proton with a bunch of enhancements has a new release out with Proton-6.13-GE-1 pulling in a bunch of advanced features and fixes.

If you're not clear on what Proton and Steam Play are, be sure to check out our constantly updated dedicated page. It's a special compatibility layer for running Windows games and apps from Steam on Linux. Proton GE is not affiliated with Valve/Steam, it also has less quality assurance versus the official Proton but often ends up with special game fixes quicker.

Proton-6.13-GE-1 pulls in support for AMD FidelityFX Super Resolution (FSR) directly into Proton, based upon a patch by developer Georg Lehmann. So with Proton GE you can now add WINE_FULLSCREEN_FSR=1 %command% as a launch option for a game on Steam and get FSR which is pretty great. Unlike games that support it directly, it's applied after the fact here since Proton as a whole is a compatibility layer so it will affect the UI too. Still, FSR for any Windows game played on Linux with Proton sounds awesome.

This release also adds in support for vkd3d/dx12 Resizable BAR patches which you can enable with VKD3D_CONFIG=upload_hvv, this could result in performance improvements.

Here's what else is new:

• FFXIV launcher workaround updated (previously used BrowserType, needed Browser instead)
• Rebased proton SDL gamepad patches on top of staging. Fixes various controller mapping issues and force feedback issues
• Steam input profiles now work again due to SDL patch update
• Warframe 5 minute no-controller crash is properly fixed now, steamclient patch is no longer needed finally
• Guilty Gear Strive 2 player mode works with two controllers now
• Grand Theft Auto V save on exit is fixed
• Swords of Legends launcher is fixed
• Resident Evil 8 crash fixed (it was crashing after they updated the game with FSR)
• Font fixes imported from proton upstream
• DXVK updated
• vkd3d updated
• FAudio updated
• Wine-mono updated to 6.2.2

To use it here's what you do:

1. Download the Proton-6.13-GE-1.tar.gz file from the release notes.
2. If this folder does not exist, create it:~/.steam/root/compatibilitytools.d/
3. Extract the archive downloaded in Step 1, and place the contents into the above directory.
4. Restart Steam if it's open which refreshes the Steam Play list for Proton-6.13-GE-1 to show up.
5. Right click on your game, go to Properties, Compatibility and ensure the box is ticked named "Force the use of a specific Steam Play compatibility tool" then select it from the dropdown box that appears.

As a reminder, if you didn't see it, as of a recent version of Proton GE you may need to remove current game prefixes setup by it to allow the games to work properly. More on that in the previous article with instructions on how to do so.
