PCHPlayer summed it up quite well. You had all of the main points. Not really any inaccuracies.
A few different points to highlight.
The 2 main reasons are:
1. Arrogance
2. Bad decisions
Arrogance:
PCHPlayer?s reference to the 16-Bit vs. 32-Bit is very accurate.
While 3dfx was claiming that the impact of 32-Bit color would reduce the # of FPS < 60, NVidia pursued that as a goal.
They were primarily a 3-D add-on card. Their big rig was dual VooDoo?s that would provide SLI (Scan Line Interleave). This is where one VooDoo would render the even horizontal lines and the other would render the odd, this resulted in really good performance.
At that time most of the games rendered in Glide(3dfx proprietary API that was very easy to learn and program for) and some used DirectX and OpenGL. Some DirectX to Glide and OpenGl to Glide wrappers came out and 3dfx had their lawyers contact the writers. Some good stuff.
Bad decisions:
They didn?t care for the differences in the VooDoo line from Diamond one of the lower quality manufactures to Cannopous, the Cadillac/BMW/Benz of the video cards. So they acquired STB to be able to manufacture all of their cards to ?ensure? better quality.
When they can out with the VooDoo 3, it was a feeble attempt in lieu of what NVidia produced. They had 3 variants of the VooDoo 3, 2000, 3000 and the 3500. They also included a TV tuner for the 3500. The only problem with their product was that it only supported 16-Bit color in games. This is where their claim for 32-Bit color wasn?t required since they rendered in 32-Bit and dithered back to 16-Bit.
They had high hopes on the VSA-100 chip, they were going to introduce 3 products, 4500 / 5500 and the external power supply requiring 6000.
The 4500 would have 1 VSA-100 the 5500 would have 2 and the 6000 would have 4. The problem with this design is that production costs were much higher than to manufacture a single chip like Nvidia was offering. The VSA-100 introduced some new technology know as T-Buffer, which included Motion Blur, Anti-Aliasing as well as a few other useless features. The Anti Aliasing was a big push then Nvidia did the same thing with their detonator drivers. It wasn?t as pretty as 3dfx but didn?t require anything special. You couldn?t utilize AA games on a VooDoo 2/3, at the time NVidia produced introduced the AA feature into the Detonator drivers, the GeForce chip was their flagship product and you could run it on a TNT (they didn?t recommend it, but it could be done). The VSA based products were several months late and Nvidia kept producing solid products that were arguably superior. The GeForce was the first to have a T&L engine too. Because of the delays in manufacturing and slow to release to the market, 3dfx which stood well above everyone else fell extremely hard. You can still get so called drivers where people have modified the installation and called them new releases at
