The very first screenshot was actually a digital photo of my monitor, everything after that was with Fraps and I don't have any artifacts when the graphics are behaving (like now). I attached a screenshot I just took so you can see what I mean. The video card is at stock settings with no OC because I wanted to see how the game played. I did enable 2X AA in the game, but that was it (there are very few video options).
Nice. Can you just drive around freely?
Sure can. When you're on a mission you'll be under attack, but once you clear out the bad guys you can drive around all you want.
