5.1.1 Freeze Bug?

Hey there @A.Weidenhammer and @Strider57 ! Welcome back to the community! I agree with Strider to try and reset your Nvidia settings first, and if that fails we would start looking to do a fresh install of the drivers, or try to swap to studio drivers. I’ve even had one user have to remove Geforce experience and do a custom install of the studio drivers.
