You can mess with the values to get what you want out of them but I run Vendetta, RTCW: ET, UpLink and a few other titles with these settings and they all look and perform great. I have not included the forceable FSAA and AF options because while they rock for some titles Vendetta tends to produce some rather odd graphical glitches, expecially with FSAA (if you want to try out FSAA and AF just take a look at the OPTIONS section of the Readme that comes with the driver).

My card is a GeForce 4 Ti4200 but I've had these settings since my GF3 days, and a buddy of mine literally copied these entries for his GF2 MX and it worked fine for him.

The current nVidia driver version is 4363. I strongly suggest you load it before you bother with any of this. You should also be running XFree 4.1 or higher.

Don't set the NvAGP to 3, because that is default. Just leave it. Also, don't set DigitalVibrance to anything less than 50 because the effect is negligable below that.

seems to solve vendetta problems...
but slower performance by about 10fps (ouch)

Only 10fps? That's interesting. You see, setting NvAGP 0 disables ALL AGP, setting you in PCI mode. Say you were in 4x AGP before? That's something like 133Mhz. Now you're at 33Mhz. Yet you only lose 10fps? When I set it, I lose about 50fps. Hmmm..

well more like 14 (at the lowest point where it is most clear), but thats from 45fps to about 30-32fps, and that is a huge difference (make it into percents and see).

Aah. I didn't know you only got 45fps.

mmm.
Actually Disabling AGP puts it in PCI mode, but at double frequency, which is the same as AGP 1x, meaning its 66MHz.

Still, that's only 1/4 of a normal AGP 4x.
