nix-config

Use when a Steam, Proton, Wine, Lutris, or Heroic game misbehaves on Linux — crashes at launch, black screen, missing DLSS / Ray Tracing / Path Tracing / DLSS-RR / Frame Generation, anti-cheat failures, shader stutter, controller or HDR or Wayland-fullscreen problems, intro-video failures ("Failed to create SourceReader", MF_E_UNEXPECTED), NVAPI "Unknown function ID" log spam, gamescope dedup black-screens, vkd3d swapchain crashes. Especially before patching or forking DXVK, vkd3d-proton, dxvk-nvapi, gamescope, Wine, or Proton; before reading RE Engine, Unreal, Unity, Source 2, id Tech, or Decima logs; or when a game is mentioned with NVIDIA Blackwell, NixOS, niri, gamescope, proton-cachyos, GE-Proton, or proton-tkg. Triggers on phrases like "won't launch", "RT/PT grayed out", "Proton fix for", "/WineDetectionEnabled", "ProtonDB", "VKD3D_CONFIG", "PROTON_USE_WAYLAND", or any moment the impulse is "let me read the Proton/Wine/vkd3d source" before checking community fixes.
