I never had any serious problems, but then I use quality components. The only RFI noticeable is the audible "pop" from my amp when the relay flicks over... Still, mechanical parts and RFI that don't need to be there is a no-no in my book. The cable is original, but isn't the problem, it's not shielded anyway so I doubt it would make much difference. The image is as fine as it can be coming from a Voodoo 1 - they were simply blurry and overly bright... Usually with reduced frame rate.
I don't get the value thing at all. The Voodoo cost the same or often more than a Rage, especially with an updated Rage already in the works at the time (Rage II / Rage 3D) and you'd have to buy a proper graphics card to use the 3DFX anyway, plus a DVD Decoder if you wanted that as many of the cheaper 2D cards didn't do that yet. I might have wanted to use the two slots that would have wasted... With all the money a person would save by using a different card they could have gotten a better CPU and more RAM, the CPU especially had more impact on performance at that time and it's what everyone I knew did - I'm not saying the Rage was particularly good, I think both ATI and 3DFX were terrible at the time as the technology wasn't there yet, there was also that NV1 from nVidia, that thing sucked. I never met anyone that owned a 3DFX card - though I did know some bloke with a Kyro II a few years later... He was mental I think as this was around the time Radeon 7000's were in.
The Voodoo did do Direct3D on paper, but it would have scored higher with me if they'd just admitted it didn't really support it. It was slow, it looked just as bad as 3DFX mode because you still couldn't disable that awful filtering and that's assuming you could get it to run without severe glitches or crashing completely. Uninstalling the card again was a nightmare too. I think a testament to this is that clearly nobody bought these 3DFX boards, the company died, nobody used silly wiring (except crossfire, which is useless) or relays quite like that again and it was all swept under the industries carpet where it belongs. The card also never really gained any ground on the demoscene, which to me spells disaster as that's where most innovations came from. Instead the scene stayed with software until moving to Direct3D and OpenGL. Whilst this was going on I thing 3DFX were still making PCI cards with loads of chips on them for a market that had moved to AGP and single chip solutions some time before. The Banshee was a step in the right direction but they appear to have then learned nothing from it and repeated mistakes they'd been making since the start - as well as a few new ones, they also took far too long to move away from 16-Bit rendering; Dithering+Filtering is not a good look, it was like Vaseline and too much beer at the same time, made me feel sick...
Nobody gives a damn about ATI these days; ATI sucks ass now, nVidia currently make better cards.
This is just how it looks to me. I remember getting that Voodoo 1 and being really excited, I'd heard about them and despite the reputation they had with local enthusiasts for being garbage I'd discovered the internet by then and found another group of people saying they had been revolutionary and had unparalleled performance for the time... I was very disappointed when I installed it only to find that what local enthusiasts had told me for years was indeed true... It didn't get on well with my Matrox Productivia either. Just as well it was free I suppose, the guy in the local computer shop was dumping about a hundred of them that had never sold about 14 years back and my Dad saved it for me, wish he'd saved more of them, we could probably have sold them years later.
