ET:QW isn't DX10 it's OpenGL.![]()
Plus, I played through lost planet to the last boss using a 2900XT played at 1920x1200 and max in-game settings.
Yeah I know - but at one point in development they were including the equivalent features - but the 2900 couldn't display them properly - that and complaints from play testers that the more complex explosion effects, etc. distracted from the gameplay lead to them being canned.

As for lost planet and call of juraz, etc. ok some of those titles were extensively tested on nVidia hardware and ATI didn't get a look in until later - but the nVidia drivers only required fairly minor tweaking to get up and running - it took ATI months to reach the same level.
