Hello, I have a 7850 and an A8 5500 APU and I just got Mirrors Edge and ran through the tutorial and first mission just fine on ultra settings with good frames, but then I got to the 3rd mission and you have to run inside from guards and my frames drop to about 2 fps and it's more a slideshow then a game. I put all the settings on lowest and stilll only get like 4 fps? Is this my CPU or my GPU or just a bug in the game?
