My computer is currently running a dual core 1.87 GHz CPU (clocked at 3.33 GHz) and a ATI Radeon HD 6670 GDDR3 GPU and I am quite sure that it is not running as fast as it should. For example, I own Grid 2 and the game says that my computer should be able to run the game at near the highest quality. The game still lags even with the quality at its lowest. I don't know if this problem is with the game or my computer because I can run MW3 on near the highest quality without any major lag. Any solutions?
