I have no clue what's going on, my drivers are all up to date, I even restored the nvidia drivers to default. I tried the High to Low trick, disabling shadows.
Then I realized that I have a GTX 570 there is no reason for this to be happening. A friend of mine with a very similar setup is in the hundreds for FPS, and I'm lucky to idle around 40-50. Get into a major town? I'm now in the 10-20 range.
ON LOW SETTINGS!
I have an i7 920, GTX 570, 6 GB of RAM and I am just confused as can be.
