Linux OBS Configuration

On OBS for Linux, there's not much options by default for high FPS or otherwise low resource recording like Windows. This is due to inefficient capture methods:

• Screen Capture (XSHM): Generally can't record above 120 FPS without lag
• Window Capture (Xcomposite): Much more efficient, but still limited to ~540 FPS
• Pipewire Capture: Generally can't record above 60 FPS without lag

If the default Window Capture (Xcomposite) works just fine for you, you can stop here. However, if you want more efficient capture methods, you will have to go with third-party plugins, which may or may not be worth it.

Third-party plugins

• NvFBC (obs-nvfbc patched for high FPS)
  • Requires NVIDIA, OBS 27 and X.Org
  • Screen capture
• OBS VkCapture (obs-vkcapture)
  • Game capture
