You can set the graphics API to DX9, DX10, DX11, OpenGL. You can set resolution, AA, AF, texture quality, etcetera.
I tried DX10 and DX11 with my HD4870 DX10.1 card and Catalyst 9.10 (just released). I had the settings maxed at 1680x1050 -- except AF at 4 and no AA (that's how I run my games too). Framerates were always above 30.
The DX11 version seemed to look better because of the lighting effects. Maybe it used some of the DX10.1 lighting effects not in DX10. But, maybe I was just imagining it.
Anyhow its a "pretty" thing to watch -- much nicer than Futuremark Vantage -- but, it has no action scenes.
