I daon't have any direct experience with Geoforce 3, but with my Geoforce 2 Ultra 63 Mb by Creative, I had no special problem with Vue and Open GL. Only, when I tryed to install the latest driver to see if there was some performace improovment, I had to came back because everything in Vue was not working. Of course Vue is not the most stable program, but the number of crash that I have is still on the average (considering also the higt number of devices that i have on my pc, from scsi card to isdn & adsl card, to pinnacle digital video card to 6 HD and more. And I'm running in win 98 FIRST edition (everything works so I don't see any reasons to jump in the dark with the 2.nd edition). And YES, Vue vorks with dual Xeon processor: in fact, I have a single Xeon 450, and I WOULD LIKE to add a second one, but I cannot find it anywhere (at least in Italy... nobody in the USA know if there Pentium Xeon 2 450 MHz is still available?)
