If you can post your predefines here that'd be great. I like the icon - looks neat
The minimum system requirements were a pretty ball-park figure. In R4 i use two openGL extensions, multitexture and pbuffer. Basically, i didn't think there's much point in supporting fall-backs if these don't exist, so it may not run on the Voodoo 3.
www.delphi3d.net has a database of extensions and which cards support them which has been built up by its users. I've just checked, and from the look of it, the Voodoo 3 doesn't support pbuffers but does support multitexture. However thats not to say that yours doesn't. try

and see if this tells you you have an extension called: WGL_ARB_PBUFFER
If you do, you're sorted.
I probably ought to give you a brief explanation of why i'm using PBuffers - its not some random decision. Basically, a lot of the effects draw graphics onto a texture, and then draw the texture onto a shape (like in your icon). At the moment, if i want to draw something onto a texture, i have to draw it to the screen, then copy the screen to the texture. This is horrendously slow, and corrupts the screen (you may have noticed what happens if you draw something to a texture, then render a scene without clearing the screen first.
PBuffers solve all this - they're very quick, don't corrupt the screen, and i believe can be a higher resolution than the screen itself. The problem comes if i try and support both. I'd have to copy the screen to a texture, draw to the screen, copy that to another texture, then draw the texture back. Its going to be a 3rd of the speed, and is probably unusable anyway.
Hope that sortof answered the problem. I know its a bit harsh, but i'd consider buying a geforce

they're getting dirt cheap now, and even the cheapest one would make any graphics application run at least twice as fast.
Not sure about the pricing on R4 yet. You may find that it contains no nag screen when its running anyway, only a notice at the start stating its not for professional use. I think i'll probably aim to hit the #1 spot on WinAmp.com again, since i make more money from doing visual-related jobs for people than i do from selling visuals, and most of those people only know of me through the original R2.
