I just did a fresh install of Fedora 15 x86_64 with KDE.
KDE is mostly unusable in Fedora 15 while it was fine in Fedora 14 (with nvidia driver).
The display seems to freeze for a few seconds every few seconds.
nvidia's driver is historically optimized primarily for opengl, 2d/xrender not so much. The latter, is used extensively in kde's default oxygen style/theming. you could try switching away from oxygen widget theme, see if that helps any, systemsettings->application appearance->style and choose some widget style other than Oxygen, say Plastique
another stab would be to switch to some plasma theme that uses less or no translucency, systemsettings->workspace appearance->Desktop Theme and choose something other than "Air" or "Oxygen"
