Specifically, by searching for "NVreg_EnableAGPFW", I found this site:


You'll need to do several things. Edit you XF86Config file so that the
"Device" section for your card includes the following line:

	Option    "NvAgp"  "3"

Then add a line in your modules.conf (or modules.conf.local, depending;
there may be others I don't know about) like so:

	options nvidia NVreg_EnableAGPSBA=1 NVreg_EnableAGPFW=1

Then make sure that you've got the "agpgart" module loaded into your
kernel. (And add a modprobe line in rc.local (for RH) or edit
/etc/sysconfig/kernel (for SuSE) to make it permanent.)

Then shut down X and reload the nvidia module. This will pick up the
options you want on the loading of the module, and it should start using
the best AGP option it can.

I'd love to hear back if this actually improves your framerates. Let me
know if you don't know how to check this. If not, you'll need to do it
before and after the changes to see the difference (if any). I didn't
see any change, but the game *feels* tons better.
