My experience with the proprietary driver and nouveau driver using an 
Nvidia Geforce GTX 650 graphics card and KDE is that compared to the 
proprietary driver the nouveau driver is horribly slow. I have on 
occasion had to use the nouveau driver when I have updated the kernel 
and there wasn't a corresponding proprietary driver, in all versions of 
fedora F18 to F21, and the system was extremely sluggish with the 
nouveau driver. Even opening the Kmenu in the task bar was extremely 
slow. I have in the past also tried to run Tux Racer under the nouveau 
driver and it was completely unusable. I didn't validate exactly what 
sort of performance the nouveau driver was providing, but the impression 
from trying to play the game was that it would be lucky if the driver 
was giving 1 FPS frame rate.
Consequently my recommendation would be for anyone with an Nvidia card 
to always use the proprietary driver. In fact, in my opinion, Fedora are 
doing users a grave dis-service by not providing/supporting the 
proprietary driver in their standard repositories like the other 2 
distros I am familiar with using (Ubuntu and Mandriva).

Steve
