Graphics? Do you get audio glitches? Current official release of Ubuntu
Studio?

I'm not booted into my stable Ubuntu Studio DAW, anyway, I don't
understand why your ATI graphics has got a that high priority :(.
FWIW, my stable DAW still is an Edubuntu /Ubuntu Studio) 10.10


OT:

For my Debian testing the Nvidia graphics priority (PCIe, no shared
framebuffer) isn't that high. Btw. it's a full preempt kernel with
threadirqs enabled using the proprietary Nvidia driver and it seems to
need more CPU capacity than a kernel-rt, but to be fair, I didn't
compared it.

Hm? I need to check if for my machine the Terratec Envy cards do have
also a higher priority than the RME card for my stable Ubuntu Studio.
