Ok, according to your sysctls, you aren't getting the AGP acceleration
at all.
Try adding these lines to your card device section:
Option "RenderAccel" "True"
Option "NvAGP" "1" # Use NVIDIAs agp
Then restart X.
Check your hw.nvidia.agp sysctls, particularly these:
hw.nvidia.agp.status.status: disabled
hw.nvidia.agp.status.rate: n/a (disabled)
You want status to be enabled, and rate to be 2x or 4x.
>From the sysctls below, it looks like the NvAGP setting is already
turned on, so that appears to be a default.
Since it's still not working, I suspect that if you check your
/var/log/Xorg.0.log file for warnings (WW) or errors (EE) related to AGP
use, you'll find something about the native FreeBSD AGP. If you are
using a GENERIC kernel ("uname -a" will tell you), that's almost
certainly what's happening.
>From what I've read, the native FreeBSD AGP doesn't always work with
NVidia cards. You'll have to compile a custom kernel with the following
line removed:
device agp
Check here for details:
http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html
Also, I'd recommend updating your ports and upgrading Xorg. You might
also want to build and install the x11/nvidia-drivers port.
