The CachyOS wiki gaming setup page (which is great even if you aren’t on CachyOS) recommends turning off shader pre-caching and increasing your maximum shader cache size if you’re using Proton-GE, Proton-EM, or Proton-CachyOS. Never had an issue other than the occasional small stutter when I enter a new area for the first time. https://wiki.cachyos.org/configuration/gaming/#pre-caching-shaders-with-proton-cachyos--ge-and--em
