So, I have a Creative 12MB Voodoo2 that's been sitting around for a good long while. I popped it into my Pentium III system for some 3Dfx goodness (and if I ever popped in a Radeon, despite those not being so hot with DOS). However, while older Direct3D and compatible OpenGL titles that use the 3Dfx card are good, the ports of Final Fantasy VII and VIII are giving me a lot of severe graphical artifacts. It's so bad, that even in CGI cutscenes, there's massive artifacting. I'll let you look at the screencap I took to see what I mean.

Just, what is causing it? It doesn't seem to do this on my nVidia cards.

This should NOT happen in CGI pre-rendered cutscenes.

With another game, I've seen that overflow artifact happen when the gamma values are set too damn high.

I set gamma all the way down to 1.1 in Voodoo2 Tweaker. It seems to still happen.

I didn't even know you could do that.

The custom graphics driver from http://www.finalfantasy7pc.com/mods/aalis-cus … raphics-driver/ will fix it, I reckon.

Huh, so I took the slider for gamma all the way to 0.75, and the artifacting is gone.

Yeah, weird. I had severe 3D artifacting on my first Voodoo2 card after I got it, but it turns out a few lines on one of the shader cores had been pushed together and were shorted. I used a very small flat-head screwdriver and separated them. Then after sitting on the shelf for a few months, I plugged it back in to verify that it was still "damaged" and lo, the card works 100% perfect. It's a Diamond Monster 3D II 8MB card.

I was having huge issues getting the 2x STB Voodoo2 12MB cards working until someone else on this forum suggested I use the FastVoodoo drivers. Works like a charm and is totally stable. Thanks, Vogons!
