Oh man, the new wolf3d
screenshots blew me away. And it's single-player, too. Hooray for the reemergance of single-player games! If it means graphics like that, I'll swap my G450 for a GeForce 3 any day.
Seriously, I've been very disappointed with my new matrox card. I bought it because I was so pleased with the 2D on my G200, but they've just skimped completely on the linux drivers. When I run dualhead, it breaks the overlay so I can't watch TV. It also reports the wrong aspect ratio, so playing DVDs is horribly distorted. 3D direct rendering gets disabled for BOTH heads in this mode. TV output does not work in linux either (and this has caused me an incredible amount of grief).
