Proton

31,371

Compatibility tool for Steam Play based on Wine and additional components

Pros of Proton

  • Official Valve support and integration with Steam
  • Regular updates aligned with Steam client releases
  • Extensive compatibility with a wide range of Steam games

Cons of Proton

  • More conservative approach to implementing new features
  • Slower to incorporate community-driven patches and fixes

Code Comparison

While both projects share a common codebase, proton-ge-custom often includes additional patches and modifications. For example, in the wine submodule:

Proton:

git submodule update --init wine
cd wine
git reset --hard <official-wine-commit>

proton-ge-custom:

git submodule update --init wine
cd wine
git reset --hard <official-wine-commit>
git apply ../patches/wine-custom-patches/*.patch

This illustrates how proton-ge-custom applies additional custom patches to the Wine codebase, potentially offering improved compatibility or performance for certain games.

Code Comparison

vkd3d-proton:

VK_DEFINE_HANDLE(VkSemaphore)
VK_DEFINE_HANDLE(VkFence)
VK_DEFINE_HANDLE(VkDeviceMemory)
VK_DEFINE_HANDLE(VkBuffer)
VK_DEFINE_HANDLE(VkImage)

proton-ge-custom:

typedef struct _steam_input_action_event_t
{
    InputActionSetHandle_t actionSetHandle;
    EInputActionOrigin eOrigin;
    InputAnalogActionData_t analogActionData;
    InputDigitalActionData_t digitalActionData;
} steam_input_action_event_t;

The code snippets demonstrate the different focus areas of the projects. vkd3d-proton deals with low-level Vulkan handles, while proton-ge-custom includes Steam Input-related structures, showcasing its broader scope for gaming compatibility.

proton-ge-custom offers a more comprehensive solution for running Windows games on Linux, including various compatibility layers and tweaks. vkd3d-proton, on the other hand, specializes in DirectX 12 to Vulkan translation, potentially offering better performance for specific DX12 titles but with a narrower focus overall.

GE-Proton

[!Warning] Running non-Steam games with GE-Proton outside of Steam is only supported using umu:

Proton runs in a container, which uses a runtime environment and libraries specifically built for use within that container. Not running it as intended results in the container and therefore its runtime not being used, which severely breaks library compatibility. It causes Wine to attempt to search for libraries on your system instead of those it was built with or intended for use with Proton. It may work if enough libraries match, but it is not the expected environment and not supported due to library differences across Linux distributions.

If you want Proton functionality outside of Steam, umu-launcher is a command-line tool that was designed to be able to mimic Steam in running the entire containerized runtime environment it needs in order to run Proton exactly as Steam does without needing Steam. Any other method is not supported.

Heroic has also enabled umu by default when using GE-Proton.

Lutris has integrated umu as the default backend used when GE-Proton (Latest) is selected as a Wine runner either globally or for any specific game.

[!Note] (1) Please note, this is a custom build of Proton, and is not affiliated with Valve's Proton.

(2) Please also note I will not assist with unofficial builds of GE-Proton. The only version of GE-Proton that I provide and will assist with builds of is the one provided within this repository, using the build system documented here.

(3) I cannot validate the accuracy or functionality of other builds that have not been built using the build system included here.

Table of contents

Overview

This is my build of Proton with the most recent bleeding-edge Proton Experimental Wine.

Things it contains that Valve's Proton currently does not:

  • Additional media foundation patches for better video playback support
  • AMD FSR patches added directly to fullscreen hack that can be toggled with WINE_FULLSCREEN_FSR=1
  • FSR fake resolution patch details here
  • NVIDIA CUDA support for PhysX and NVAPI
  • Raw input mouse support
  • 'protonfixes' system -- this is an automated system that applies per-game fixes (such as winetricks changes, environment variables, Easy Anti-Cheat workarounds, overrides, etc)
  • Various upstream Wine patches backported
  • Various wine-staging patches applied as they become needed
  • NTSync enablement if the kernel supports it.

Notes

  • Warframe is problematic with VSync. Turn it off or on in game, do not set to Auto
  • Warframe should have a frame limit set in the game. An unlimited framerate may cause slowdowns
  • Warframe on NVIDIA: you may need to disable GPU particles in game otherwise the game can freeze randomly. On AMD they should work fine.

Full patches can be viewed in protonprep-valve-staging.sh.

Installation

You must have the proper Vulkan drivers and packages installed on your system. VKD3D on AMD requires Mesa 22.0.0 or higher for the VK_KHR_dynamic_rendering extension. Check here for general driver installation guidance.

Manual

Via asdf, the version manager

There is an unofficial plugin for installing and managing GE-Proton versions with asdf (the universal version manager), it follows the same process as the manual installation but makes it a lot easier. Managing versions by removing and updating to newer versions also becomes easier.

To install by it first install asdf, and then proceed to add the 'asdf-protonge' plugin and install the version you want.

asdf plugin add protonge

# Or install a version from a tag
asdf install protonge latest

It's also possible to use the asdf plugin in Flatpak installations, by customizing the target compatibilitytools.d path. For more settings check the plugin's official documentation.

After every install you need to restart Steam, and enable proton-ge-custom.

Native

This section is for those that use the native version of Steam.

  1. Download a release from the Releases page.

  2. Create a ~/.steam/steam/compatibilitytools.d directory if it does not exist.

  3. Extract the release tarball into ~/.steam/steam/compatibilitytools.d/.

    • tar -xf GE-Proton*.tar.gz -C ~/.steam/steam/compatibilitytools.d/.

  4. Restart Steam.

Snap

This section is for those that use the Steam Snap.

This unofficial build isn't supported by GloriousEggroll nor Valve and wasn't tested with all possible games and cases. It can behave differently from the upstream builds. Use at your own risk.

Manual
  1. Download a release from the Releases page.
  2. Create a ~/snap/steam/common/.steam/steam/compatibilitytools.d/ directory if it does not exist.
  3. Extract the release tarball into ~/snap/steam/common/.steam/steam/compatibilitytools.d/.
    • tar -xf GE-ProtonVERSION.tar.gz -C ~/snap/steam/common/.steam/steam/compatibilitytools.d/
  4. Restart Steam.
  5. Enable proton-ge-custom in Steam.

Building

  1. Clone this repository by executing:
git clone --recurse-submodules https://github.com/gloriouseggroll/proton-ge-custom

  1. Drop any custom patches into patches/, then open patches/protonprep-valve-staging.sh and add a patch line for them under #WINE CUSTOM PATCHES in the same way the others are done.

  2. Apply all of the patches in patches/ by running:

./patches/protonprep-valve-staging.sh &> patchlog.txt

in the main proton-ge-custom directory. Open patchlog.txt and search for "fail" to make sure no patch failures occured. An easy way to do this is like so:

grep -i fail patchlog.txt
grep -i error patchlog.txt

  1. Navigate to the parent directory containing the proton-ge-custom folder.

  2. Type the following:

mkdir build && cd build
../configure.sh --build-name=SOME-BUILD-NAME-HERE
make redist &> log

The build will be placed within the build directory as SOME-BUILD-NAME-HERE.tar.gz.

Enabling

  1. Right click any game in Steam and click Properties.
  2. At the bottom of the Compatibility tab, Check Force the use of a specific Steam Play compatibility tool, then select the desired Proton version.
  3. Launch the game.

Options

Enable HDR

It should work if you have:

  • A compositor with HDR support
  • A game with HDR support.
  • A monitor with HDR support.
PROTON_ENABLE_HDR=1 %command%

[!NOTE] Enabling HDR auto-enables the wine-wayland driver as it is a requirement. As of right now, in-game Steam overlay WILL NOT work with Wayland enabled. Please also note that Steam Input also does not work properly with the wine-wayland driver due to the overlay being broken.

Enabling NTSync

For NTSync to work, your kernel must be version 6.14 or newer and built with CONFIG_NTSYNC=y or CONFIG_NTSYNC=m. If using CONFIG_NTSYNC=m, a module loading configuration is required followed by a reboot:

/etc/modules-load.d/ntsync.conf

ntsync

You can also manually enable the module without reboot, just keep in mind the above configuration is needed for it to persist after reboots:

sudo modprobe ntsync

Environment variable options:

Compat config stringEnvironment VariableDescription
PROTON_LOGConvenience method for dumping a useful debug log to $HOME/steam-$APPID.log. For more thorough logging, use user_settings.py.
PROTON_DUMP_DEBUG_COMMANDSWhen running a game, Proton will write some useful debug scripts for that game into $PROTON_DEBUG_DIR/proton_$USER/.
PROTON_DEBUG_DIRRoot directory for the Proton debug scripts, /tmp by default.
wined3dPROTON_USE_WINED3DUse OpenGL-based wined3d instead of Vulkan-based DXVK for d3d11 and d3d10. This used to be called PROTON_USE_WINED3D11, which is now an alias for this same option.
nod3d12PROTON_NO_D3D12Disables DX12.
nod3d11PROTON_NO_D3D11Disables DX11.
nod3d10PROTON_NO_D3D10Disables DX10.
nod3d9PROTON_NO_D3D9Disables DX9.
noesyncPROTON_NO_ESYNCDo not use eventfd-based in-process synchronization primitives.
nofsyncPROTON_NO_FSYNCDo not use futex-based in-process synchronization primitives. (Automatically disabled on systems with no FUTEX_WAIT_MULTIPLE support.)
nontsyncPROTON_NO_NTSYNCDo not use the ntsync kernel module for in-process synchronization primitives.
forcelgaddPROTON_FORCE_LARGE_ADDRESS_AWAREForce Wine to enable the LARGE_ADDRESS_AWARE flag for all executables.
heapdelayfreePROTON_HEAP_DELAY_FREEDelay freeing some memory, to work around application use-after-free bugs.
HOST_LC_ALLSet value to a locale to override all other system locale settings for a game. This variable should be used instead of LC_ALL.
enablenvapiPROTON_ENABLE_NVAPIEnable NVIDIA's NVAPI GPU support library.
noforcelgaddDisable forcelgadd. If both this and forcelgadd are set, enabled wins.
oldglstrPROTON_OLD_GL_STRINGSet some driver overrides to limit the length of the GL extension string, for old games that crash on very long extension strings.
cmdlineappend:Append the string after the colon as an argument to the game command. May be specified more than once. Escape commas and backslashes with a backslash.
xalia or noxaliaPROTON_USE_XALIAEnable Xalia, a program that can add a gamepad UI for some keyboard/mouse interfaces, or set to 0 to disable. The default is to enable it dynamically based on window contents.
seccompPROTON_USE_SECCOMPEnable seccomp-bpf filter to emulate native syscalls, required for some DRM protections to work.
nowritewatchPROTON_NO_WRITE_WATCHDisable support for memory write watches in ntdll. This should only be applied if you have verified that the game can operate without write watches. This can improves performance for some very specific games.
WINE_FULLSCREEN_FSREnable AMD FidelityFX Super Resolution (FSR), use in conjunction with WINE_FULLSCREEN_FSR_STRENGTH. Only works in Vulkan games (DXVK and VKD3D-Proton included).
WINE_FULLSCREEN_FSR_STRENGTHAMD FidelityFX Super Resolution (FSR) strength, the default sharpening of 5 is enough without needing modification, but can be changed with 0-5 if wanted. 0 is the maximum sharpness, higher values mean less sharpening. 2 is the AMD recommended default and is set by GE-Proton by default.
WINE_FULLSCREEN_FSR_CUSTOM_MODESet fake resolution of the screen. This can be useful in games that render in native resolution regardless of the selected resolution. Parameter WIDTHxHEIGHT
WINE_DO_NOT_CREATE_DXGI_DEVICE_MANAGERSet to 1 to enable. Required for video playback in some games to not be miscolored (usually tinted pink)
COPYPREFIXSet to 1 to enable. If -steamdeck is used on steam (or SteamDeck=1 is set), copies the game's prefix and shader cache from the game partition to the local steam steamapps folder. Logic is reversed if -steamdeck not enabled (or SteamDeck=0)
fsr4PROTON_FSR4_UPGRADEAutomatically download amdxcffx64.dll and upgrade games with FSR 3.1 to use FSR 4. Version to download can be specified by supplying it as a value, like so PROTON_FSR4_UPGRADE="4.0.1", instead of 1. Downloads version 4.0.2 of the required DLL by default. This option also disables AMD Anti-Lag 2 currently due to various issues.
fsr4hudPROTON_FSR4_INDICATOREnable the FSR4 watermark at the top left portion of the screen.
fsr4rdna3PROTON_FSR4_RDNA3_UPGRADEIdentical to PROTON_FSR4_UPGRADE but for RDNA3 GPUs. Enables some required compatibility options and downloads version 4.0.0 of the DLL by default.
fsr3PROTON_FSR3_UPGRADE
dlssPROTON_DLSS_UPGRADEAutomatically download and use newer versions of nvngx_dlss(d|g).dll DLLs. Version to download can be specified by supplying it as a value, like so PROTON_DLSS_UPGRADE="310.2", instead of 1, to download version 310.2.1.0. This option also sets DXVK_NVAPI_DRS_SETTINGS to use the latest preset. If you provide your own config for it through this environment variable, your configuration is going to be applied..
dlsshudPROTON_DLSS_INDICATOREnable the DLSS overlay at the bottom left portion of the screen. This is exactly the same as FSR4_WATERMARK=1
xessPROTON_XESS_UPGRADE
sdlinputPROTON_USE_SDL or PROTON_PREFER_SDLUses SDL input instead of HIDRAW/Steam Input.
waylandPROTON_USE_WAYLAND or PROTON_ENABLE_WAYLANDEnables the Wayland driver.
wow64PROTON_USE_WOW64Enables wow64.
WAYLANDDRV_PRIMARY_MONITORSpecify primary monitor where the value is something like eDP-1. Requires the Wayland driver.
PROTON_ENABLE_MEDIACONVEnable media converter for winegstreamer. This is not needed for winedmo, since the mediaconverter implementation of the codecs doesn't override the underlying implementation.
WAYLANDDRV_RAWINPUTA value of 0 disables unaccelerated input and uses accelerated input. Any positive real number (like 0.5) adjusts the sensitivity of rawinput. Requires the Wayland driver.

Credits

The GE-Proton project contains some of my personal tweaks to Proton, but a large amount of the patches, rebases and fixes come from numerous people's projects.

While I tend to get credited for my builds, a lot of the work that goes into it are from other people as well. I'd like to take some time to point a few of these people out of recognition.

In future builds, I plan to make clearer and more informative Git commits, as well as attempt to give these people further crediting, as my README may not be sufficient in doing so.

TKG (Etienne Juvigny)

I and many others owe TKG. In regards to both Wind and Proton. He has dedicated a lot of time (2+ years at least) to rebasing Wine and Proton patches, as well as making his own contributions. Before he came along, I did some rebasing work, and mainly only released things for Arch. These days he almost always beats me to rebasing, and it saves myself and others a lot of work.

Guy1524 (Derek Lesho)

Derek was responsible for the original raw input patches, as well as several various game fixes in the past, just to name a few: MK11, FFXV, MHW, Steep, AC Odyssey FS fix. He has also done a massive amount of work on Media Foundation/MFPlat, which should be hopefully working very soon.

Joshie (Joshua Ashton)

Joshua is the creator of D9VK and also a huge contributor of DXVK. He is also known for his recent DOOM Eternal WINE fixes and also many of the Vulkan tweaks and fixes used, such as FS hack interger scaling.

doitsujin/ドイツ人 (Philip Rebohle)

Philip is the creator of DXVK and a heavy contributor of VKD3D. He also put up a lot of my bug reporting for Warframe years ago when DXVK started.

HansKristian/themaister (Hans-Kristian Arntzen)

Hans-Kristian is a heavy contributor of VKD3D and he also created a lot of WINE patches that allowed WoW to work.

flibitijibibo (Ethan Lee)

Ethan is the creator of FAudio, and he also listened to my Warframe bug reports years ago.

simmons-public (Chris Simmons)

Chris is the creator of the original 'protonfixes' project. The portions of 'protonfixes' I've imported are what allow customizations to be made to prefixes for various Proton games. Without 'protonfixes' many games would still be broken and/or require manual prefix modification.

wine-staging maintainers

I also of course need to thank the wine-staging maintainers: Alistair Leslie-Hughes, Zebediah Figura and Paul Gofman

They have contributed many patches to staging, far beyond what I have done, as well as kept up with regular rebasing. A lot of times when bug reports come to me, if it has to do with staging I end up testing and relaying information to these guys in order to get issues resolved.

Additionally, a thank you is owed to Andrew Aeikum (aeikum), and kisak (kisak-valve) for regularly keeping me in the loop with Proton and fsync patches, as well as accepting pull requests I've made to fix Proton build system issues, or listening to bug reports on early Proton patches before they reach a Proton release.

Patrons

And finally - to all of my patrons that have supported me, thank you so much. It's because of you that I've been able to keep this project going, getting bug fixes reported, getting Proton/Wine issues fixed, getting various hardware and/or game fixes handled, and so on. Thanks to you, I have been able to use the spare budget in order to both help support the other people that make my project possible, as well as get things necessary for testing such as new game releases or specific hardware that hits odd issues. It's had a huge effect not just for this project, but a large trickle down effect.

My wine-staging co-maintainers are often able to ask me for testing games, or testing on different hardware if they don't have access to it. This also trickles into both Proton bug reporting and Lutris bug reporting, as I'm able to provide bug testing and feedback and custom builds and upgrades to them as well. I'm also able to test driver related issues for things such as mesa and getting things reported + patched. This in turn leads to early patches for Mesa, the kernel, VKD3D, and other packages on my copr repositories as well. The trickle down effect is just one gigantic awesome rabbit hole for getting things fixed. Thank you once again.
