-protonfix added for ship graveyard simulator (and prologue, Thanks Alistair Leslie-Hughes!)

-Fsync has been disabled on all Uplay titles -- it causes Uplay to hang on "Looking for patches" when initiationg a new prefix. Esync works fine.
-Various Uplay titles that have a vulkan native mode (Rainbow 6 siege) need the overlay disabled in order not to crash. DX11 mode works fine.
-For games that have a protonfix that uses the uplay overlay disable -- if creating a new prefix you will need to relaunch the game a second time. Uplay completely removes any pre-existing configurations on first launch, so any appending to the file gets removed. Upon re-launch the option will be re-appended and uplay will then see it.
-uplay likes to hang out after the game has closed -- make sure you close it in the task manager.

(1) A large amount of changes have been added in this WINE release for HID gamepad support, as noted:

HID joystick enabled by default.

Two additional pending upstream patches have been added on top of this for better functionality. Currently proton's SDL gamepad patches have been disabled in favor of WINE upstream's HID implementation. I did my usual test with Guilty Gear Strive and everything seems to appear OK. The test is done in the dojo, with one xbox controller and one ps5 controller -- both controllers showed up fully functional for player 1 and 2, and proper button mappings and button images showed and worked.

Another note regarding GG Strive in particular with the testing:

# note you have to take some funky steps for 2 player to work in training mode (not linux specific):

I have not tested any force feedback games and am not sure if patches for that have been added. Unfortunately re-enabling the SDL patches will require a -massive- list of reverts, so for the time being as mentioned, the default HID joystick impementation is being used and proton's SDL patches disabled, at least until proton upstream rebases.

(2) Deathloop seems to very much dislike alt+tabbing out. For me it would freeze the game. Other than that it appeared to be playable.

NOTE: Due to the symlink updates for steam cloud saves, you will want to remove your old game prefixes so that they are properly regenerated with new symlinks. Your games may not launch otherwise:

Proton Game and Prefix Launch troubleshooting:


  • Import proper steam cloud save fixes from upstream proton

  • Import Project Cars III window focus fixes from upstream proton

  • Import Tokyo Xanadu Xe+ ASF fixes from upstream proton

  • Import Guilty Gear Strive cloud save path fixes from upstream proton

  • Import multiple font fixes from upstream proton

  • Fixed crash with Hitman 2

  • Added workaround for FFXIV broken login button
    There are two executables shipped with FFXIV for the launcher -- ffxivboot.exe and ffxivboot64.exe.
    Each one has a 'new' launcher mode and an 'old' launcher mode. The 'old' launcher mode is what we use to login on linux,
    however it uses mshtml and jscript by default, which break the 'Log In' button.
    The normal way to usually get around this is to just press enter after you input your password,
    but that can be annoying when you accidentally hit the button.

    Here is where the workaround comes in. The ffxivboot.exe has a built-in function called IsTransgaming,
    which tells the old launcher mode to use CEF instead of mshtml+jscript. When IsTransgaming is triggered,
    CEF gets used and it fixes the log in button. ffxivboot64.exe does -not- have this. Additionally, a
    patch was needed to trigger IsTransgaming. So, FFXIV has been configured to use ffxivboot.exe instead of ffxivboot64.exe,
    the patch to trigger IsTransgaming has been applied, and the old launcher mode is configured to be used.
    This allows the old launcher mode to be fully functional.
  • Added FFXIV frame timing configuration for DXVK to resolve some stuttering, noted here: doitsujin/dxvk#2210

  • Re-added missing mfplat stub that was accidentally removed from staging's mfplat patches. This re-fixes some unity games that had broken mfplat in 6.14 (Notably Power Rangers: Battle for the Grid)

  • Added pending upstream wine patches for Riftbreaker

  • Added pending upstream winelib patch (fixes

  • vkd3d patch added for Diablo II Resurrected (Note: This was added in case it fixes other games. Running non-steam games with proton is -not- supported).

  • Wine + Wine-staging updated to 6.15

  • DXVK updated to latest git (fixes Endless Legend and Borderlands 2 crashing)

  • vkd3d updated to latest git

  • Faudio updated to latest git

  • Rebased proton sdl joystick patchset. Removed:

[PATCH] winebus: Make it more explicit how we are checking for duplicate devices
