going by that picture you seem to have a bottleneck somewhere... your cpu and gpu usage are very low. try increasing the screen rez if your monitor will allow it. then turn the settings up to high and blur on but set low.
if you cant increase the res increase the higher end settings. and see if your gpu usage jumps up. if it doesnt then over clock the cpu to 3.6 if you can.(as long as you have the required cooling, ie none stock cooling)
