ULTRAKILL
ULTRAKILL's fast shooting in VR, but only on an old game build.
The catch: Broken on the current game version and paused by its author.

General step from us -
Install ULTRAKILL (Steam)

Black screen in the headset
This mod uses OpenXR. Check the active OpenXR runtime matches how you connect (the Set your VR runtime step), then start Link or Virtual Desktop before the game. General tip from us
Controllers don't show up
Start Link, Virtual Desktop or SteamVR before the game, and make sure the controllers are awake before launch. General tip from us
Stutter or low frame rate
Lower the in-game resolution or render scale first, then shadows and volumetrics. Close overlays you don't need. General tip from us
The mod didn't load at all
Recheck the game version against the creator's page; a game update is the most common cause. Then reinstall the mod files. General tip from us
