Actually, RTC timing is not CPU-intensive.  If Myth were to fall back 
from RTC to software timing, that would be more CPU-intensive.  
(Software timing can provide as precise a timing mechanism as RTC, but 
is more CPU-intensive than using the _hardware_ RTC.)  I don't even know 
if Myth provides a software-timing mechanism as a fallback for RTC, though.

NVIDIA's installer doesn't necessarily remove everything properly.  
Check out 
http://download.nvidia.com/XFree86/Linux-x86/1.0-8178/README/appendix-c.html 
to see what's left on your system.  Make sure you clean off all the 
OpenGL libs and links that were installed by NVIDIA (not the MESA ones) 
and re-run ldconfig.
