new kde on f13 is very noisy!

[moabi2000]

FWIW I just tried the nouveau driver in F14 and am very impressed. KDE
desktop effects work great, and scrolling is much smoother than with
nvidia blob and less tearing. Google earth is a bit slow but perfectly
usable.

However, still have high kwin cpu use, so not necessarily
nvidia-related. Reported here:
https://bugs.kde.org/show_bug.cgi?id=234463

I would strongly suggest giving nouveau a try, it is MUCH better than
even 6 months ago, at least for my hardware (quadro 140).

Cheers
M.
