FPS gained (1280x1024):
Low: 40-60 FPS, no drops at all
Highest: 15-25 FPS, not really playable. It may seem smooth in the video, but it was really hard to play.

FPS gained (1280x1024, everything on High, distance and details view at 50%):
30-40 most of the time
20-30 drops depending on the time in-game. At night I get more FPS than day. Probably depends on that there are not that many cars and people going around the city at night.
Very bad FPS on this one folks, I'm pretty dissapointed. It's playable but I was hoping for everything on Very High and at least 40FPS
