Two things:
1. Reset the game’s graphics options to medium before launching it with the mod. certain graphics setting like DLSS may interfere with the mod.
2. the mod uses the CyberEngineTweaks modding framework. Since each version of the CET unfortunately only works with the Cyberpunk version it was made for, you have to make sure that both the mod and your Cyberpunk are up-to-date.
Unrelated, but while am at it:
Once you got it working, make sure to actually read the instructions that are offered to you in the headset on launch. That’s time well spent. Hectically clicking stuff away just makes things less enjoyable. :)
