This means PlayStation 4 gamepads as well as fighting gamepads and other controllers will behave much more like they do on Windows. If you would like your gamepad to be emulated as if it were an Xbox controller, please use the Steam client controller mapping feature. If the controller cannot be accessed directly, due to a permissions issue, it will continue to be presented like an Xbox controller.
  • fsync hang and crash fixes.
  • Add support for fsync configurable spin count, might help performance but disabled by default. Try setting WINEFSYNC_SPINCOUNT=100

  • Update DXVK to v1.3.
  • More window management and mouse cursor focus fixes.
  • Fix for joystick input lag and rumble support in certain games, especially Unity titles.

4.2-9:
  • Fixes for multiplayer functionality in Mordhau, SOULCALIBUR VI, and others with problems from 4.2-8.

  • DXVK 1.2.1 has been rebuilt with a modern compiler. This should increase performance especially for 32-bit games. (Note, if you build Proton yourself in Vagrant, you will want to make clean and vagrant provision to take advantage of the new compiler; or simply destroy and re-create the VM.)
  • Update FAudio to 19.06.
  • Fix for more games on non-English locales, like GRID.
  • Fix controller rumble in some games, including Team Sonic Racing.
  • Improve font rendering in SpellForce 3.
4.2-5:

  • Better support for games that use very old steamworks SDKs, including Lost Planet.
  • Fixed various problems with the build system, and added a new top-level Makefile to make simple builds much easier.
3.16-6:
  • Support for gnutls >= 3.0, which should fix many networking issues with games. Note the Steam runtime doesn't ship this yet, so your distribution will need to provide it. For users on distros that don't provide this, Steam Play will still use the Steam runtime library as before. When the Steam runtime is updated, this will be available for all users. In our testing, we saw improvements in Eve Online, DOOM (2016) multiplayer, and HELLDIVERS.
  • Other networking fixes, too. In particular, Hitman 2 and Metal Gear Solid 5 should now be working online.
  • DXVK is upgraded to 0.94. In addition to the DXVK release notes, Dishonored 2 and Middle-earth: Shadow of War appear to be working with this release.
  • Configurable support for forcing the LARGE_ADDRESS_AWARE mode. This can help some games which run out of memory when run in Steam Play, for example Bayonetta.
  • Further improvements to FAudio.
3.16-5:

  • Better support for embedded Chromium-based web browsers. Games and launchers that contain an embedded web browser may now work better.
  • Update DXVK to 0.93. Also include a fix for some Unity VR games when run with DXVK, like SUPERHOT VR and Job Simulator.
  • Compatibility improvements for changing paths between Linux and Windows using the Steam API. Among other things, this should fix Steam Controller icon images in certain games.
  • Minor fixes for PulseAudio users with certain hardware.
  • For developers, optional support for Vagrant, which should ease the process of creating Proton build VMs.
3.16-4:
  • Proton now ships with corefonts support. This should fix many games with missing text, or that crash due to missing font support.
  • Significant Steamworks compatibility improvements. This should fix SOULCALIBUR VI's network failure when launched through Steam Play.
  • For Direct3D games (both DXVK and wined3d), Nvidia cards are now reported as if they are actually AMD cards. This prevents games from trying to load the Windows-only nvapi library and crashing or giving very bad performance.
  • Mouse focus and clipping improvements.
  • Upgrade OpenVR SDK support.
  • Fix for a keyboard input issue in S.T.A.L.K.E.R. games.
3.16-3:

  • Enabled more optimizations and instruction sets for Wine
  • Minor alt-tab fixes for Unreal Engine 1 games
3.16-2:
  • DXVK is again built as a Windows DLL, due to incompatibilities with the Steam runtime. This should fix widespread crashes with Direct3D 11 titles.
  • DXVK updated to 0.90.
  • Fix for alt-tab crashing on Unreal Engine 1 games, including Deus Ex.
  • PROTON_USE_WINED3D11 is now called PROTON_USE_WINED3D to reflect that this variable affects more than Direct3D 11. The old name still works as an alias.
3.16-1:
  • Rebased Proton patches onto Wine 3.16.
  • Updated Vulkan support in Wine to 1.1.86, plus support for transform feedback.
  • DXVK has been updated to 0.81 plus support for transform feedback which should fix missing models in many D3D11 games. Transform feedback requires using Mesa git or NVIDIA's 396.54.09 Vulkan Beta driver.
  • DXVK's d3d10 mode is now enabled by default.
  • DXVK is now built as a native Linux library, which may give a small performance boost, and should make debugging easier for DXVK and driver developers.
  • Missing textures for models in some VR games has been resolved.
  • Ask the window manager to bypass the compositor in fullscreen mode. This may improve performance in some situations.
  • All new makefile-based build system.

  • More display ratios have smaller resolutions available.
  • Fix a crash on old versions of SDL.

  • DXVK updated to v0.70, view that changelog here: https://github.com/doitsujin/dxvk/releases DXVK's DX10 support is not yet enabled.
  • Fullscreen games should more consistently gain keyboard focus on Ubuntu with gnome-shell. This can also help with games that auto-minimize on launch.
  • Some useful default logging can be enabled with PROTON_LOG=1 %command% in the Steam game launch options. Logs will be dumped to $HOME/steam-$APPID.log. WINEDEBUG can still be set in user_settings.py for more extensive debugging.
  • Debug scripts are no longer dumped to /tmp/ by default. They must now be enabled with PROTON_DUMP_DEBUG_COMMANDS=1 %command% in the Steam game launch options. They have also been moved to /tmp/proton_$USER/.
  • Controllers will hopefully no longer cause long delays on startup on some systems (winehq bug 45084).
