New NVIDIA Linux Drivers -- 5:54 pm CST, Update by A.T. Hun

NVIDIA has released version 1.0-2802 of their drivers for Linux. The biggest two changes in these new drivers are support for the GeForce4 family of cards and the addition of anisotropic filtering. They seem to give me a big of a framerate boost in general. Anisotropic filtering is pretty amazing. I set it to the highest level with the command:

export __GL_DEFAULT_LOG_ANISO=3

I dropped from almost 120 fps to 73 on the "four" demo but only from 70 to 60 on the UpsetChaps demo 2. Basically anisotropic filtering makes the textures towards the horizon seem much more clear. The difference was immediately obvious to me. Obviously, it comes with a pretty stiff performance penalty. I plan on testing it at various levels with and without antialiasing. Yes, I like my GeForce3 Ti200 :) Thanks HardOCP.

UPDATE! Wow! People talk alot about antialiasing, but in my book anisotropic filtering has a far greater visual impact. Using the "maximum" setting on mpterra1 in Quake III: Team Arena is stunning. Of course, my framerates also drop to nearly unplayable levels at 1024x768 with seven bots. I found this page on NVNews in their GeForce3 preview that shows the effects of anisotropic filtering. Most impressive.
