Nouveau driver is fast in Fedora 21 -_-

[poma]

Scrolling is super fast in Firefox using the nouveau[.ko][_drv.so] modules under
Fedora 21. In fact the whole system seems fast, but that's another feature.
Has anyone else noticed notable performance of the Linux & Xorg X11 nouveau video modules
for NVIDIA graphics chipsets driven on:

x64/32 mamma board / 1 CPU
VGA Chipset: G98 (NV98) / Family : NV50
Xfce 4.11


Merci beaucoup
