Keep seeing the issues people are having with these games. I can say that I, or anyone I know, have never had one issue with either game. And there is not a forum for people to post how great their cards perform....so. Here is a article that may help one or two of you.

Comment: Another big issue is some users new to Win10/11 don't realize that high performance settings in Adrenalin do not always carry over to a game or application. It must be assigned as the graphics card to use...and that is done through Windows.
