Strap yourself in and get ready to experience the future of gaming realism and interactivity that only the GeForce GTX 400 Series of GPUs can provide. Taking advantage of PhysX, CUDA, DirectX 11, and 3D Vision, Supersonic Sled straps you on a high powered test rocket and hurtles you down a six mile long track in the Nevada desert at speeds in excess of 800 miles an hour. You’ll have to avoid falling rocks, destroy buildings and bridges, and avoid flying off the side of a massive cliff.
