I have the same problem with KDE with nvidia drivers - it seems worse with the latest ones from rpmfusion, and worse in 4.5 compared to 4.4. (Not sure when the change came in, first betas of 4.5 seemed fine). There are a bunch of bug reports already (eg https://bugs.kde.org/show_bug.cgi?id=234463) - though there seem to be multiple issues and a lot of noise in the bug reports. For me, turning off the blur effect helps, but not much. On my laptop I have switched to gnome for the moment as it gives me approx 50% more battery life in normal use (OO Word + calc, kmail, firefox, amarok, R etc) than same apps under kde. KDE apps under gnome are a pain though (you have to start kmail twice to get akonadi running first, super slow scrolling in akregator etc etc). Nouveau didn't work well for me last time I tried, but will probably make the jump to F14 and try again sometime soon. sorry!
