No, it turns off the NVidia AGP driver: # sysctl dev.agp dev.agp.0.%desc: Intel 82875P host to AGP bridge dev.agp.0.%driver: agp dev.agp.0.%location: slot=0 function=0 dev.agp.0.%pnpinfo: vendor=0x8086 device=0x2578 subvendor=0x1028 subdevice=0x0157 class=0x060000 dev.agp.0.%parent: pci0 The FreeBSD agp device is still active. > > <SNIP> > > # sysctl hw.nvidia > > hw.nvidia.agp.card.rates: 8x 4x > > hw.nvidia.agp.card.fw: supported > > hw.nvidia.agp.card.sba: supported > > hw.nvidia.agp.card.registers: 0x1f000e1b:0x00000000 > > hw.nvidia.agp.status.status: disabled > > hw.nvidia.agp.status.driver: n/a (unused) > > The above lines confirm that AGP is off.

I've never worked with a system that had more responsive video, and that's using the twinview feature to run two monitors. Makes me want to work from home all the time, since my work desktop is a pokey old 440Mhz hacked together piece of junk that was built 5 years ago. Just because NVidia wrote their own AGP driver doesn't mean every one of their cards must have it to function well. I believe it is mentioned in the linux readme that some cards are better off with the AGP driver that comes with the OS. I know I read something to that affect somewhere.
