With my ATI Radeon 9600, after a few minutes my games crash but not my computer, i can speak with my friends on Mumble.

Thank you for taking the time to report this bug and helping to make Ubuntu better. You reported this bug a while ago and there hasn't been any activity in it recently. We were wondering is this still an issue for you? Can you try with latest Ubuntu release? Thanks in advance.

Recently, i've installed Hardy Heron on a computer with this card, now the game don't crash but it's very very slow.

Please attach the following files to the bug report as individual uncompressed file attachments. :
- the output of uname -a
- your X server configuration file (/etc/X11/xorg.conf)
- X server log file (/var/log/Xorg.0.log)
- The output of lspci -vvnn

Thanks in advance.
