I never tried to play around with the Nvidia CP to get extra options/better image quality in the past, I just stuck to what the in-game graphics option offered most of the time, but now I want to start to since I think I'm missing out on possibly better IQ, performance... etc
So I got Bioshock during the sale and loaded it up, the graphics setting are lacking to say the least, so I went to the nvidia CP and tried a couple of things for the first time, mostly turning almost everything to max to see what happens, it obviously improved the IQ (especially the AA) but it introduced some input lag which is obvious, after some experimenting I turned everything back to normal and shut the game off.
So, as a total virgin to using external programs/drivers to improve the game's graphics/performance beyond what's offered in the in-game option, what would be the best/most optimal way of doing it and which CP options should I change or ignore/not screw around with ?
