Just a few things off the top of my head...
-The Rendition Verite (V1000) was the first "true" 3d card that I can remember. It was capable of running accelerated Quake and the included Indy Car Racing II was breath-taking at the time with it's high framerate (30fps), high resolution (640x480), and bilinear filtering. I remember sitting in amazement as I watched the ICR2 demo play when I first bought this card. It was truly the first amazing 3d acceleration I had ever seen in my life. Probably the closest thing to it was the Race Drivin/Hard Drivin arcade game, with all of it's blocky polys and 10-15fps goodness.
-The article gives us a huge list of 3d cards, but little depth into the actual performance or market penetration of any of them. Most of these cards are barely worth mentioning. Even at the time, some of these cards sold in miniscule numbers or performed horribly. That's not to say that they shouldn't have been mentioned, but how about focusing on the major players a little more?
-How about 3dfx's "16-bit color is just fine!" rhetoric when Nvidia upped the ante with 32-bit color? I think the reason that 3dfx neglected to move to 32-bit color at the time was because they had tested it and performance on their cards was horrible. Hey, I bought 3dfx's bullshit at the time, mainly because I wanted to run Quake 2 as fast as possible.
I could go on, but the bottom line is this article isn't much of a "history" at all. It's nothing more than a list of cards with specs and brief summaries. How disappointing.
