I just got a Valusbox K-6 AMD 475 computer that is supposed to have a 16 meg AGP 3-D accelerator with 3DNOW technology. Problem is, all my 3-d games run like crap. Unreal is actually slower than it is on my P II 233, both running in software mode. Does this thing actually count as a 3-D accelerator? Do I have to download some kind of driver or something?
