Black screen in the headset
This mod runs through SteamVR. Start your link (Quest Link, Air Link or Virtual Desktop) first, then SteamVR, and only then the game. If SteamVR shows the headset but the game is flat, close the game and launch it again the way the creator's steps say. 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
