Gaming on Linux with an older GPU levels up with DXVK-Sarek v1.12 bringing major new features

By Liam Dawe - 16 Apr 2026 at 10:25 am UTC

You don't have to get left behind with gaming on Linux if you have an older GPU, thanks to projects like DXVK-Sarek keeping them alive.

This fork of DXVK (the Vulkan-based implementation of D3D8, 9, 10 and 11 for Linux / Wine), is aimed it those of you with GPUs that do not meet the Vulkan 1.3 requirement of the main DXVK / Proton. Giving you the benefit of various game upgrades and fixes from later DXVK versions but keeping it supported for older GPUs.

DXVK-Sarek v1.12.0 brings dyasync (Dynamic Asynchronous Pipeline Compilation, replacing the old async patch) and the port of D7VK, which adds Direct3D 3, 5, 6 and 7 support to DXVK-Sarek. Plus, lots of fixes from upstream DXVK for many more games to run so plenty to look forward to.

The GitHub release page explains dyasync in more detail:

Starting with this release, DXVK-Sarek includes dyasync, enabled by default. This replaces the traditional async patch and removes the need for separate async builds, so from now on there will be no more async-only or non-async releases, only a single unified build.

When a shader is encountered for the very first time, it must be compiled synchronously, this is unavoidable and may cause a brief stutter. However, every variant after that is handled differently. A variant is created whenever the game uses the same shaders with a different combination of fixed-function state (blend mode, depth test, cull mode, render pass, etc.), each unique combination counts as a new variant.

When a new variant is needed, dyasync does not stall the game to compile it. Instead, it grabs the closest already compiled pipeline for those same shaders (perhaps one compiled with different blend settings) and uses it as a placeholder while the correct variant builds in a background thread. Once the background compilation finishes, it silently swaps in the correct pipeline. This reduces stuttering and improves frametimes.

This approach is safer than the traditional async patch because something valid is always being rendered on screen, there are no invisible or missing objects. That said, during the brief placeholder period, minor visual inaccuracies are possible (e.g. slightly wrong blending). Use in multiplayer games at your own discretion.

Dyasync can be disabled by setting dxvk.enableDyasync = False in dxvk.conf, in the DXVK_CONFIG environment variable, or by using the environment variable DXVK_DISABLE_DYASYNC=1.

And, officially, Proton-Sarek has now been retired. This was their own special Proton build with DXVK-Sarek. Instead, they suggest using Proton-CachyOS which is supported.
