FWIW, with a -lowlatency kernel on Ubuntu 11.10, I've had much better 
experience with the NVIDIA driver than with the Nouveau driver. With 
Nouveau, navigating around the desktop, and leaving/entering the GNOME 
Shell overview in particular, caused a tonne of xruns. Those xruns 
disappeared when I installed the NVIDIA driver again.

I don't know if Nouveau with a RT-patched kernel would perform even 
better, but my current setup works very well for me -- I'm rock-solid at 
8ms latency and can push it to 4ms without too much drama.

Thanks
