Can i use VR Performance Toolkit

I want to use VR Performance Toolkit but I have to put files in the game. So I wanted to ask so I don’t get banned.

No you can’t. EAC doesn’t ban you with how VRChat has it set up, it just won’t work and it will throw an error when you try to load into your home world.

You won’t be banned for it by EAC, however it won’t work as EAC will flag it as illegitimate and prevent the game from launching.
