It seems like you have an unbalanced machine. Your graphics could use more power. I think your due for an upgrade if your into high demand gaming.

For best performance turn off V sync and AA. Those can dramatically increase performance. Turn of blurriness if such option exist.

AA = auto adjust and what is Vsync
