@exxos My first PC (bought at a computer auction; the same one that a few months later I would buy this exact VR setup incidentally) was a Cyrix 686 based system.
After a while Unreal came out and I thought I'd have to upgrade.
At the time, I had enough money for a (then 2nd from the top) P2 266MMX system with 32Mb RAM. The RAM amount was low and I'd run out of funds for a 3D card, so it was choppy as hell. Eventually I was able to buy a Voodoo2. My god! Going from SW rendering to a Voodoo 2 was a real life changing moment. (It was still a bit choppy, because the Voodoo card was £2-300 so I still couldn't afford extra RAM).
Eventually, I got an extra 32MB and all was well.....for a while. You know how it goes.
EDIT: I do remember some cards had non standard IRQ DMA or address ranges which mucked things up. Was telling the missrs just yesterday that installing a game on DOS, you would setup the sound by testing it out on certain settings. If you heard sound, then all was well, otherwise it would lock up the system. Seemed so normal back then.
