I tried'em last night too, they looked good, but weren't exactly done yet

That's to be expected tho'... I didn't have near as bad problems as mech, but I couldn't play with it for a long time since gameplay was jittery, and I have enough trouble battling with a slow connection :|
BTW: Didn't try the D3D renderer, only the openGL one, on my MX...
