===== Capturing and sharing Proton logs =====

  - Right-click on the game in Steam and select Properties.
  - Under Launch Options, add the following:

<code shell>
PROTON_LOG=1 PROTON_LOG_DIR=/home/jas/steam-proton-logs %command%
</code>

===== game-performance =====

To use CachyOS’s [[https://github.com/CachyOS/CachyOS-Settings/blob/master/usr/bin/game-performance|game-performance]] script to switch power profiles while a game is running, add the following to each Steam game’s Launch Options:

<code shell>
game-performance %command%
</code>

Combined with the Proton logging options:

<code shell>
PROTON_LOG=1 PROTON_LOG_DIR=/home/jas/steam-proton-logs game-performance %command%
</code>

===== Pre-caching shaders with Proton-CachyOS, -GE and -EM =====

Pre-caching of shaders is not needed on CachyOS, as Proton-CachyOS already contains all the necessary codecs.

  - Go to Steam Setttings -> Downloads
  - Go to the SHADER PRE-CACHING section
  - Disable Shader Pre-caching
  - Disable Allow background processing of Vulkan shaders
