Or you can just do this:
/etc/X11 is the directory for the file
The way I done mine was.
Install the RPM's by double clicking on them. After that edit
XF86Config-4 the bloody file and add: Load "glx". Then edit the video module and change "nv" and "vga" to nvidia.
Restart X and log in and then you will run anything OGL.
