Would really appreciate if someone could tell me in plain english (or link to if already been done) what each of the nvidia settings mean and do? Have an 8800gt but i don't think i'm getting the best out of it due to my lack of knowledge. For example, CoD United Offensive seemed to run better when i was using 7300gs, i've messed around trying lots of different settings in the Nvidia control panel but i just can't get the game to look good and play well! I was expecting to be able to play an older game like this on all of the highest settings possible with this card.
