I just upgraded from a 5450 to a 6870 and was wondering what people are finding the optimal settings to be? Especially the framerate cap, which I am not sure I fully understand yet. I do find that if it is too high and I get up to 150 fps for a bit and it drops back to 60-75 it will cause a stutter. Its not nearly as bad as when it would die to 15 fps on the 5450, but I would still like to optimize my gaming experience. I'm running with 4 GB ram, and an AMD Phenom II X4 (quad 3.2 Ghz) in case either of those will make a huge difference to answers.
Thanks all, and happy demon slaying!
