Limiting frame rate (FPS) in Direct3D games on Linux

Limit the frame rate in Direct3D games on Linux by launching them with:

DXVK_CONFIG="dxgi.maxFrameRate = 120" <command to launch game>

This should limit the frame rate to 120.

If you are launching them from Steam, place this in the game's Launch options:

DXVK_CONFIG="dxgi.maxFrameRate = 120" %command%

Adjust 120 to your preference.

This is very useful in Vampire Crawlers, which otherwise runs about 700fps and turns my laptop into a space heater!
