The seniors of the family are going to deliver highest performance in every resolution. The GeForce 8800 GTS and GeForce 8800 GTS 320MB can’t match the leaders and their speed bottoms out to below 25fps in high resolutions. The GeForce 8600 GTS allows playing this game with comfort in 1280x1024 only, if you use full-screen antialiasing. The GeForce 8500 GT has low performance and you can’t play normally on it unless you lower the resolution, disable FSAA, and reduce the level of detail.
