just ran it on the only DX11 machine at my work, unfortunately that consists of a Dell Inspiron with a i5 760 and a HD5450 1GB DDR3 the physics test on the stock i5 gave almost the exact same FPS as kaktus's run. but the 5450 was a total slide show, most FPS i saw in the whole thing was about 4FPS but most of the time we were talking 1-2FPS and in the second High temple test it was .5FPS

I am looking forward to seeing how the GTX 480 handles it when I get home. Infact i am going to compared my 480, 460 and 5870 and see whats up
