Although these programs are nice to use with the game they can be used and behave like a cheat program.
We are working on cracking down on the cheating that is happening so ReShade and similar programs will not be usable.
If such programs are on the system, please make sure to remove those completely or it can cause issues with the game running properly.
If issues still persist even after it has been uninstalled, please try and remove the program completely and then re-install the game as well.
