Fedorda Core 6 slowdowns

I'm not sure if I'm having Fedora, X, SDL or Nvidia
problems.

I have an FC4 install working fine.
On the same machine FC6 will go thru periods where display
updating bogs down terribly. Screen updating stops completely
for a few seconds and then continues.

I see this especially in Lincity, XKobo Deluxe but
other text only apps seem slow too.

I've got a very fast dual processor with an NVidia card
and I'm using the latest NVidia drivers. Glxgears seems OK,
not as fast as it is on FC4 but around 2K FPS.
I've gotten 3K FPS on FC4.

I've done some Google searches and can't find anyone
with similar issues. Any ideas?

No ideas but you might try running the "top" command at a high priority
and shipping its output to a disk file. Cancel it immediately after a
slowdown then look at the output and see if you can figure out what is
eating your cpu cycles. You will probably need to use an update cycle of
two seconds.
