You guys whine too much. Turn down some settings. I throughly enjoyed the demo on my X1550. Ran great at lower details. 30 fps average at 1024x768 with all settings on Low except textures on Medium and sound on High. Got 40 fps at 800x600 but there is a significant drop in sharpness at that resolution.
Lowering the resolution on an LCD makes the graphics and text look like crap. That is not an option for me. My LCD's native res is 1680x1050 and that is where it stays, except in the few games I have that don't support that resolution.
