Limiting FPS with MangoHUD in Steam

Part of Linux

If you playing on Linux you might have the issue where you don't want to use VSync - mainly when running a weird special setup with multiple monitors, with rotations and different refresh rates - but at the same time you don't want your PC to be running that card game at 900 FPS and using Energy / putting Heat out like there is no tomorrow.

If the game is running on VULKAN - or via the Proton compatibilty layer - you can limit the FPS by using Vulkan FPS Limiter.

If that doesn't work / isn't possible, you can use MangoHUD:

sudo apt install mangohud
MANGOHUD_CONFIG=no_display,fps_limit=90 mangohud %command%

This will limit the FPS to 90 and NOT display the MangoHUD Overlay on the game.
