--- Comment #7 from Marek Olšák maraeo@gmail.com 2010-12-22 13:21:40 PST --- The game should not crash the X server. If it does, you are probably using indirect rendering, which might happen with 32-bit apps on x86_64 systems. Indirect rendering is buggy, slow, contains only a subset of features r300g offers, and gets very little testing AFAIK. So please make sure the game uses direct rendering. I should mention that using a 32-bit system may help.
