Around the time that I installed the Crimson update it appeared that the peformance in FIFA 15 and Call of Duty: Advanced Warfare has decreased. FIFA 15 gets increadible lagspikes in the penalty area. Peformance in COD is just terrible overall. I used to run it steadily at 60 fps @ 1440p but now that's unplayable. I was forced to lower the rendering resolution to be able to get remotely acceptable framerates.
Both these games aren't very properly optimized for AMD cards but they're not very demanding either. I'm wondering if someone has heard something about degrading peformance after the Crimson update in certain games and how to fix it.
