How to fix graphics stuttering in Linux games using DXVK cache

✨ Quick Answer

Graphic stuttering when playing Windows titles on Linux through Proton or Wine occurs because the games' DirectX graphics calls are translated to the open Vulkan API in real time using the DXVK library. This generates a CPU consumption spike to compile each new texture shader the first time it is displayed on screen.

Quick Diagnostics

Cause

DXVK shader compilation occurring in real-time during gameplay

Solution

Enable async shader compilation via DXVK_ASYNC=1 variable

Cause

Corrupted shader cache inside Steam prefix directory

Solution

Clear shadercache directory contents and rebuild cache

Step-by-Step Solution

1. 1

   Step 1: Activar la compilación asíncrona de shaders en Proton/Steam

   If you play titles running under DirectX 11 or DirectX 9, you can tell DXVK to load shaders asynchronously in the background by adding variables to Steam launch options:

   BASH Copy

   # Activar la traducción gráfica asíncrona de fondo
   DXVK_ASYNC=1 %command%
   

2. 2

   Step 2: Configurar la compilación de shaders por hardware (GPL)

   On modern NVIDIA and AMD drivers (with support for the Vulkan Graphics Pipeline Library extension), add environmental variables to speed up rendering:

   BASH Copy

   # Forzar compilación paralela de la GPU
   dxvk.enableGraphicsPipelineLibrary = True __GL_SHADER_DISK_CACHE_SKIP_CLEANUP=1 %command%
   

3. 3

   Step 3: Optimizar los controladores de video Mesa

   If you use AMD graphics cards, make sure to enable the high-performance texture shader RADV compiler:

   BASH Copy

   # Forzar el compilador RADV en lugar de opciones antiguas
   RADV_PERFTEST=aco %command%
