I've used the beta and near final versions at my former workplace with the following configurations:

K6-something 400 MHz, Matrox G200, ATI Rage Pro, Win2000 and Win98

PII 266, Matrox G200, ATI Rage Pro, Win2000 and Win98

Pentium 200, Riva128, Voodoo 2, Win98

Pentium III 450 Riva128, TNT2, Win98

We also had a hardware compatibality lab, that tested it a wide range of hardware, using D3DX.

I am currently using the final version with:
Pentium II 350, MPact3D, Win98

As for it switching to software, have you tried enumerating the devices and see that it's recognizing the hardware?

On my 300mhz k6-2 the CreateContext call will sometimes fail occasionally, but if I run it again everything starts to work again. Even worse, on my friends 450MHZ Pentium III with a S3 Trio (bleh!) it hardly ever works at all, even using the software modes in D3D.

Has anyone else experienced problems with D3DX? Or is my program just terribly coded

Yeah, I've been enumerating things. I've looked over my initializationg code countless times, and I haven't seen any problems but it's likely that the problem is somewhere in my code. I just wanted to make sure that I didn't spend a large amount of time looking for a bug which wasn't there.
