Linux Gaming

Limiting FPS with VULKAN in Steam

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:

• In Steam, find the game you want

• Right Click > Properties

• Under the command to start the game, write:

DXVK_FRAME_RATE=90 %command%

Where 90 is the FPS you want the limit set to.

Limiting FPS with MangoHUD in Steam

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 you can’t use VULKAN / Proton Compatibility Layer, you can use MangoHUD.

• Install mangohud

sudo dnf install mangohud

• On Steam, find the game you want, Right Click > Properties, and under the command to start the game write

MANGOHUD_CONFIG=nodisplay,fps_limit=90 mangohud %command

Where 90 is the FPS you want the limit set to.
