FlatOut is another race simulator, which special feature is a very precise physical model. Moreover, there are not so many rules in the game, you can hit your rivals during the race, do whatever, the most important thing is to be the first at the finish line. From the graphics point of view the game looks very nice, although it is not a true masterpiece.
During the tests we revealed a performance limitation set at 100fps. However, in 1600x1200 it is already possible to compare the mainstream graphics cards performance and draw some conclusions. RADEON 9800 XT turned out slightly faster than GeForce 6600 GT AGP, while RADEON X700 XT, on the opposite, falls slightly behind this card.
When we enable FSAA and anisotropic filtering the performance difference between high-end cards gets visible in 1280x1024 and up. Note that here ATI based solutions are about 10% ahead. In the mainstream segment, NVIDIA won the laurels, although in 1600x1200 GeForce 6600 GT AGP yields to RADEON 9800 XT equipped with 256bit memory bus. As for the RADEON X700 XT, it runs almost as fast as GeForce 6600 GT.
The Multi-GPU mode by NVIDIA works fine in this game, although you will be able to really benefit from it only in high resolutions with enabled full-screen anti-aliasing because of the above mentioned performance limitations.
