intel video driver is buggy in games

[Christophe Dumez]

Binary package hint: xserver-xorg-video-intel

I'm playing a few openGL games on Ubuntu. They used to work fine on Gusty (using default i810 driver) but I get a lot of graphical artifacts since I upgraded to hardy (and new intel driver). This makes the games quite impossible the play because graphical bugs are numerous.

The games I tried are enemy-territory (and TCEtest mod) and CS 1.6 (with wine).

I've been having the same problem, but mine affects much more than just my games. It also affects many other OpenGL apps such as Celestia.

I filed a bug, with a screenshot.

Indeed, your screenshot does look a lot like what I have on my computer too. This is the same problem.

It may affect other apps than Games but I only tried games.
