As I said in the message with the image, this problem is with the ATi
drivers, not the game per se. According to some speculation from the
Linux ATi community at
<http://www.rage3d.com/board/forumdisplay.php?s=&forumid=61>, this is
due to some math errors when performing Z buffer tests on the card,
however I do not know why the problem appears, really. This artifacting
of the UT200x based games is nototrious since the introduction of the
3.2.x drivers, being less notorious (in my *personal* experience) in
drivers versions 3.2.8 (which add other type of artifacting, not so
dramatic, and not so often at least).
