I have a TNT2 ultra and I use pete's openGL all the time unless the game itself is uncompatible with it. As for the card's driver I use Detonator 5.45 because I think that once you get into 6.xx the drivers start to be optimized for GeForces. I may be wrong though. anyway when I tried newer versions like the new 11.xx I get little annoying problems such as not being able to select all the resolutions in some pc games.
BTW I use Powerstrip to overclock my TNT2 ultra. I have the TNT's memory running at 212Mhz and the engine clock running at 162Mhz. If you decide to overclock you TNT2 ultra you should try it a little bit lower than my settings and slowely move up to my settings if your pc stills boots and is stable. Don't go above those settings though as you could blow out your card.
mm..Adair, what's that Powerstrip? I recently read some of computer magazines...isn't it a little bit too dangerous to overclock the graphic card? hmm...I would feel a pity if I damage my $57 TNT 2 card... hoho
yeah of coarse it's risky overclocking things, but my friend who had the exact same card as me told me the "safe" amount to overclock to and I've had my card running stabily at that speed for about half a year now.
I don't know if there would be a difference between TNT2s made by different companies, but my friend and I both have the diamond Viper V770 Ultra.
The only problem you will have when overclocking is a heatsink/fan that doesn't cool the GPU enough to make up for the extra heat of overclocking. So I also have a $60 600Mhz Celeron overclocked to 900Mhz with a $40 heatsink/fan.
S3 purchased most of Diamond's assets a year or so ago. At that time Diamond only updated its latest cards after the acquisition. Now S3 has focused its attention on products other than its video cards (most likely because theirs aren't worth a darn), and thus Diamond updates its cards as often as 3DFX will most likely update its cards after its buyout - not at all. So basically the only place to receive updates for Diamond cards is Nvidia's Detonator drivers, which generally don't work on my V770 Ultra (2.08 is STILL the latest set that works with it). I still think it's a nice card, I'm just not thrilled about using drivers that are more than a year old...
That's strange I'm using detonator 5.45 and it works perfectly. I can even use 1100 to play games on but for some reason I can't choose every resolution I should be able to and the monitor won't ever wake up without a reboot. That doesn't happen with 5.45 though.
