Hello,
Today I've updated my Radeon HD 7770 to update 13.9, which came out yesterday. Before this update, my computer game the graphical performance a 7.6, which is perfect, but now after this update, it says 7.3. I wasn't worried at first but after playing some games I noticed I was getting fps drops now and then. Just, from 60 fps to 20 and then back up to 60 again. It's really bugging me and I hope someone can explain this to me. (Aren't updates supposed to make it better?)
