Proton-For-Old-Vulkan or "Sarek"

Sarek (Proton-For-Old-Vulkan): A custom Proton build with DXVK 1.10.3 for users with GPUs that support Vulkan 1.1+ but not Vulkan 1.3, or for those with non-Vulkan support who want a plug-and-play option featuring personal patches.

Why does this repository exist?

Because there are still users with GPUs that support Vulkan 1.1+ but not Vulkan 1.3, as well as others with non-Vulkan support. Those who can use DXVK often rely on older Proton versions, which suffer from lower compatibility and performance compared to newer builds. Meanwhile, users dependent on WineD3D frequently face poor gaming experiences. This repository provides patched versions of Proton and/or Proton-GE, offering better performance with DXVK v1.10.3 and WineD3D mainly trough the custom parameter PROTON_TWEAKS, along with other enhancements, ensuring a smoother experience for both Vulkan and non-Vulkan setups.

Please be aware that this is a custom build of Proton and is not affiliated with Valve's Proton. If you encounter any issues specific to my Proton build from this repository that do not occur with Valve's version, kindly refrain from submitting a bug report to Valve's bug github. Instead, please report the issue directly on this GitHub. Thank you for your understanding!

GPU List:

Here its the GPU List of the ones on witch its recommended to use this Proton Build

NVIDIA:

On NVIDIA cards, it should be all the ones that are stuck on the 470 drivers, previous drivers like 440, 415, 390 and Nouveau users.

Intel && AMD:

Any GPU or iGPU that is OpenGL only or has a Vulkan API lower than 1.3.

Parameters:

Proton:

This are set on the Launch Options of a game on Steam, example:

PROTON_USE_WINED3D=1 PROTON_NO_ESYNC=1 mesa_glthread=true %command%

The Optimzation variables are set on the same way on the launch options

Environment Variable Description
PROTON_USE_WINED3D=[0/1] Use OpenGL-based wined3d instead of Vulkan-based DXVK for d3d9 to d3d11.
PROTON_NO_D3D12=[0/1] Disables DX12.
PROTON_NO_D3D11=[0/1] Disables DX11.
PROTON_NO_D3D10=[0/1] Disables DX10.
PROTON_NO_D3D9=[0/1] Disables DX9.
PROTON_NO_ESYNC=[0/1] Do not use eventfd-based in-process synchronization primitives.
PROTON_NO_FSYNC=[0/1] Do not use futex-based in-process synchronization primitives.
PROTON_FORCE_LARGE_ADDRESS_AWARE=[0/1] Force Wine to enable the LARGE_ADDRESS_AWARE flag for all executables.
PROTON_HEAP_DELAY_FREE=[0/1] Delay freeing some memory, to work around application use-after-free bugs.
PROTON_ENABLE_NVAPI=[0/1] Enable NVIDIA's NVAPI GPU support library.
PROTON_OLD_GL_STRING=[0/1] Set some driver overrides to limit the length of the GL extension string, for old games that crash on very long extension strings.
PROTON_USE_XALIA=[0/1] Enable Xalia, a program that can add a gamepad UI for some keyboard/mouse interfaces.
MESA_GL_VERSION_OVERRIDE=4.6 MESA_GLSL_VERSION_OVERRIDE=460 Only for Mesa, it changes the default string of the OpenGL version to OpenGL 4.6, faking it and making the game believe that your GPU supports that version. The game may open or not; if it doesn't open, your only solution is Software Rendering.

Optimization:

System:

First of all lets start with the must have, Gamemodem, Zram and MangoHud.

Tool/Library Description Link
GameMode GameMode is a daemon/lib combo for Linux that allows games to request a set of optimizations to be temporarily applied to the host OS and/or a game process. GitHub - GameMode
Zram-Generator Zram, formerly called compcache, is a Linux kernel module for creating a compressed block device in RAM. GitHub - Zram-Generator
MangoHud MangoHud is a Vulkan and OpenGL overlay for monitoring FPS, temperatures, CPU/GPU load and more. GitHub - MangoHud

My personal recomendation its to search a tutorial for the installation of the three in your favorite Linux Distro ;P

Sarek:

These are the custom parameters introduced in Sarek to enhance performance and provide fallback rendering options.

Environment Variable Description
PROTON_TWEAKS=[0/1] Enables all the PROTON_TWEAKS_* parameters for general performance optimization
PROTON_TWEAKS_PROTON=[0/1] Adds a set of Proton/Wine optimizations as environment variables
PROTON_TWEAKS_NVIDIA=[0/1] Adds a set of optimizations for NVIDIA proprietary drivers
PROTON_TWEAKS_MESA=[0/1] Adds a set of optimizations for MESA drivers
PROTON_VK_SOFTWARE=[0/1] Uses Lavapipe for CPU-based rendering for Vulkan, supporting API version 1.3, PROTON_TWEAKS comes enabled by default
PROTON_OGL_SOFTWARE=[0/1] Uses LLVMpipe for CPU-based rendering for OpenGL, supporting API version 4.6, PROTON_TWEAKS comes enabled by default

Below are benchmarks comparing performance with PROTON_TWEAKS enabled and disabled:

Requirements for Using Lavapipe (Vulkan Software Rendering):

  • Mesa Version: 20.3 or newer
  • CPU: Multi-core recommended for better performance

Requirements for Using LLVMpipe (OpenGL Software Rendering):

  • Mesa Version: Any recent version (LLVMpipe is well-supported in current Mesa releases)
  • CPU: Multi-core recommended for better performance

Additional Tips:

  1. If that of a above its not enought, you might want to check newer kernel versions or patched/customiced kernels(zen, liquorix, xanmod, cachyoskernel, clearkernel, etc), i personally recomend the vanilla kernel tought

  2. You might want to use the drop shader cache command of the linux kernel before playing a game, you should do:

    sudo su
echo 3 > /proc/sys/vm/drop_caches
exit

  3. You might want to use Mangohud to cap your fps and set the fps cap mode, this its an example:

    MANGOHUD_CONFIG=fps_limit=60,fps_limit_method=early,no_display mangohud %command%

    What does this do? MANGOHUD_CONFIG=parameters,parameters overwrites the current MangoHud config. Another option is to add the following to the MangoHud config file:

    fps_limit=60
fps_limit_method=early
no_display

    Also, remember that for MangoHud to work with OpenGL games, you should use mangohud --dlsym instead of just mangohud in the Steam Launch Parameters.

    You can remove the no_display option (which hides the MangoHud HUD), change the fps_limit value to any number you like, and change the fps_limit_method to early (for smoother frametimes) or late (for the lowest latency).

    Check out the MangoHud GitHub repository for more information and configuration options.

Building:

Follow these steps to add to your Proton Build the Sarek patches:

1. Download/Compile Proton

  • Option 1: Compile your Proton build from source.

  • Option 2: Download a precompiled Proton build (GE-Proton or Valve's stable release are the only ones officially supported).

2. Get the Sarek Patches

  • Clone or download the Sarek-Patches dir from this repository.

3. Rename the Proton Executable (if necessary)

  • If you're using GE-Proton, no need to rename anything, as the default proton file works out of the box.
  • For Valve's Proton builds:
    • Rename proton (from the Sarek-Patches dir) to something else like proton-ge.
    • Rename the proton-valve file from the Sarek-Patches to proton.

4. Modify Compatibilitytool.vdf and Proton Files

  • Edit both compatibilitytool.vdf and proton files to reflect the name of your build (replace "Sarek" with your custom build name).

  • Optionally, make additional tweaks to wine.inf or other configuration files as needed for your specific build.

5. Make the make.sh Script Executable

  • If you want a build with normal DXVK or DXVK-Async, make the appropriate script executable:

      chmod +x /path/to/make.sh       # For normal DXVK
  chmod +x /path/to/make-async.sh  # For DXVK-Async

6. Run the Build Script

  • Execute the script with superuser privileges:

      sudo /path/to/make.sh

  • or for the async build:

      sudo /path/to/make-async.sh

When prompted, provide the path to the Proton build you downloaded or compiled.

7. Enjoy Your Custom Proton Build!

  • Thats all, enjoy :)
