HELP! My Game is Lagging

I just installed my copy of 2k12 and I'm getting the same problems I got at first with 2k11, the game is jittery/stuttering a bit. My graphic card is an ATI Radeon 6700 and I have an Intel i7 processor. I have everything set on high, everything on with 8x anti aliasing. For 2k11 someone here told me to hit alt+tab and change the affinity and that worked for 2k11 but it's not working for 2k12. I've done benchmark tests and I'm getting around 130 frames per second. What could be the problem? Help please.

I had a crazy micro stuttering after installing my game today and it was there even when I toned down my video settings. And then I remembered I had this same issue in PES 2012, so I unplugged my controller from front panel USB and plug it into the IO panel at the back and voila all problems gone. Try it if you have a controller like me and the game runs smooth without the controller.

No my controller's censor was already in the back, it was 2k's anti aliasing. I turned it off in the game and turned it on in the catalyst control center and it solved my problem.

Alright good to hear. Maybe when I switch to AMD I might come back to this solution! XD
