Humm ... good feedback here
I love anandtech! Haha =)
Well,
1) I'm using plain ol' quake III, with plain ol' win2k reference drivers (I mean really old ... the new ones will lockup my sys).
2) Yep, I have a KX133 (Abit KA7). I don't remember installing the via4in1 thingy. I know that I downloaded it, installed it, but after the last format I don't think I put it again. But just for the record, I think these Via drivers optimize AGP performance. My card is PCI. I could be wrong.
3) Now here is where the discussion really starts cookin'. Let's start from the top. I have TWO diamond cards: a Viper V550 AGP (RivaTNT) and a Stealth III 32MB PCI (Savage4). I have two systems: my trusty ol' PII-300 on a "??" chipset, and a Athlon 650 on an Abit KA7.
If I use a OS based on the 9x kernel (windows 95, 98 or ME), both systems will SEVERELY lockup when scrolling text. Only a reboot will do. To solve this problem, I have to "decelerate" the card, that is, going to it's setting and setting the slider to the second-worse setting. With this option, DirectX won't work ... I now have a 2D-only card.
With Windows 2000, there is no lockup OF THIS TYPE. My PII-300 + TNT is tremedously stable with nVidia's reference drivers. With the Athlon+Savage4, the old drivers are stable, but the newer ones cause random (but constant) lockups. This happens with Diamond and S3 reference drivers.
I've contacted Diamond about this, but they only sent me a Bios Settings FAQ. Further contact got me no answers. I'm really stumped on this one.
wow, this was a long post ... if you read up till here, congratulations
Well, gotta go ...
