Check out Tweak3d's list of tweaks; yes it hasn't been updated since the 256sdr but there are some good tweaks in there. I was very happy with the performance of the original gf2mx I got for my aging p2-450. I will probably be replacing the pos ati card in this machine once the gf4's come out, driving down the price of the gf3's.
I got the latest ones & had problems. After screwing around for awile & starting in safemode, I got them in & working...now I'm playing with Tweak3D's ideas.
Every time I put the "latest" drivers in & restart, I get the BSOD & it's NDisp4.dll. Since that is the same as in there now (2188) any suggestions? The working drivers are 09/27/01 & the newer ones are 12/xx/01. I have copies from nvidia & PNY & they are the same damed .dat file. Tnis is just stupid. I'm going back to the abacus.
