I am currently running Ubuntu Feisty with ati :(. I switched from the proprietary fglrx driver to the aiglx driver so that I could run beryl without xgl. When I ran World of Warcraft with the fglrx driver it worked pretty well. Now when I run it with aiglx it starts at the login screen and renders one frame about every 5 seconds. Other 3d programs like Blender and Second Life run fine under aiglx. Anyone have any ideas of what I can try?
