Hey, I've got an unusual issue in which several of my games in GOG Galaxy are now displaying "No DC" in the topleft corner of the game screen and I'm not entirely sure what that means. It's only appeared in the last few days and it's a little annoying to have up there. This may be related to some of the update issues but again, I don't know if it is or not.

Try this:
Open the Nvidia control panel - manage 3D settings - set Threaded Optimization to Auto

That actually worked. thank you for the assistance, I appreciate it
