Im on a laptop with a Ati 9000 chipset. So I have to use the Xorg Radeon drivers as ATI stopped supporting this chipset long ago. So I cant use AtI drivers. Issue I have is with horrible flash playback. For example this movie clip on IMB is like a slide show. Like maybe 3 frames a second.
I dont know if its the Xorg driver or the flash plugin or both together that is causing this. I'm running Arch Linux and installed latest flash from Adobe site. But that didnt improve anything. When I view that Batman clip in task manager its showing the plugin using 50-60% CPU.
