Hi

"GNOME 3 includes the new “GNOME Shell” user interface which requires 3D
video acceleration, which Fedora provides with open source drivers for
Nvidia, AMD (ATI) and Intel, including support for “Sandybridge” GPUs.
With Fedora 15, 3D support in Nouveau, the open source Nvidia driver, is
now available by default, and the mesa-dri-drivers-experimental package
does not need to be installed."
