When I first got it, it wasn't compatible with anything, but it appears they've got their heads on a little straighter cause they've got better drivers out. Everything works fine and it's a great deal for a good card. I'd get it if you want to save money and still have an excellent card.
No, GeForce no longer runs at AGP 1x under Irongate, nVidia got it's latest drivers set, it's working at 2X now.
Viper II is extremley fast for UT and Quake 3
It's compatible to any games, I never had any compatibility issues with it
S3TC doesn't enhance visual quality, it just compresses textures for enhanced 32-bit perfrormance, but in UT you can get a special MeTaL driver for Viper II where you can use a thing called "large textures" wich have a beautifull visual quality...
The Viper II is a very fast card in 16 bit colour, and not so shabby in 32 bit either. If you're on a budget, I'd highly recommend that card. You basically get nearly high end performance, for a very reasonable price.
Main problem is that its T&L doesn't seem to be that fast, at least in Direct3D. If you care about T&L, that is. (I don't, but I thought I'd let you know.) Or rather it's a weird one. The performance doesn't drop at all with the number of lights. With 8 lights per poly, it's quite a match for the GeForce. With 1 light, the GeForce is way faster.
And speaking of UT and the MeTaL driver, please DON'T install the compressed textures from the second CD. It can cause some very distant polygons, when viewed from certain angles, to be filled with solid purple or gray or other crap instead of a texture. Mind you, it's a very rare thing. On most levels this doesn't happen, but on very few levels (e.g., DM-2ndSpaceBeacon) which do have enough depth and juust right polygon placement, it can get annoying.
Also, in case you run into trouble and the MeTaL driver doesn't load in UT, I'd advise you re-install the 4.20 patch after you install the MeTaL driver. It fixed that problem for me.
