You _must_disable_ DRI if you load the nVidia driver!
nVidia does _not_ use the Direct Rendering Infrastructure
(DRI) for OpenGL, it provides a full OpenGL over X11 (GLX)
capabilities!
[ Think of DRI v. GLX as the old "Mini Client Driver" (MCD)
v. the full "Installable Client Driver" (ICD) support for
OpenGL in the Windows world. Having a full GLX
implementation is better, long story. ]
Comment out the line
Module "DRI"
near the top of your XF86config/Xorg configuration file. The
DRI section at the end will be ignored (don't worry about
commenting it out).

On FC3+/RHEL4+, yes. There are many "proper" ways to set
this up. This is the easiest way although not the most
"proper" (just copy the dev files to /etc/udev/devices/) ...
1. Re-install the nVidia driver (creates /dev/ entries)
2. Run:
cp -a /dev/nvidia* /etc/udev/devices
chown root.root /etc/udev/devices/nvidia*

udev is the culprit.

xvidtune
But open your monitor's manual and get the maximum specs for
your monitor and set them in the XF86Config/Xorg file first.
