Fun video, but even more fun comment section. People have strange recollections of the time, really, although a handful of comments (at the time of posting) talk about the one really great point of 3dfx later lineup, the hardware antialiasing. That was a pretty neat feature, one not seen since.
Boy had we discussions in the classroom back in the day. Playing games in higher resolutions (for the time, which meant above 800x600) was only possible if you had a Riva TNT, or a Voodoo 2 SLI configuration. The Voodo 2 SLI was leaps and bounds ahead in performance, but it also necessitated having three graphics cards. With me being the computer equivalent of a freedom loving hippie at the time, I went with a Riva TNT card primarily because it offered almost (single) Voodoo 2 level performance without resorting to proprietary APIs, and it ran games in 32 bit color, which looked pretty good, but then I also had the hardware to back the card up, as 3dfx add-in cards generally scaled much better with lower end hardware, or cheaper alternatives, like the wonderful AMD K6-2, the absolute bane of my existence and the reason why until this day I will not use AMD hardware in my own builds. To be fair though, nVidia released improved drivers, named Detonator, at a later date that increased performance on lower tier hardware by a whole lot, but at the time, well, it was what it was. A Riva TNT was unlikely to compete with a single Voodoo 2 on any system that was not at a high end level - and even then not fully.
As a downside, some games only came with software rendering or glide (or, in the case of the Final Fantasy VII PC port, only worked with 3dfx cards, and nothing else), which was a bit of a letdown - although funnily enough, some 3dfx products of the time were not capable of running the entirety of their own API. Yes, looking at you, Voodoo Rush. That was an unmitigated disaster.
Always like strolls down memory lanes. Kind of want to bet that all those 3dfx fanboys in the comments are the same sort of people that complain endlessly about anti-consumer practices by greedy corporations while championing a company that invented trying to drive board partners out of the market and having an unhealthy grip on the market with a proprietary API that eventually was phased out because it hindered innovation and adaptation.
