Does anyone know the real reason why 3DFX went out of business? I always assumed it was just a bad business model; that for whatever reason, the little pressure nVidia applied made 3DFX.
3DFX really still had a good hold on the industry, especially with regards to Glide. Glide was widely adopted, and (from what I hear) was a great API.
They were also a household name with the small number of enthusiasts back then, and could have easily mounted a comeback, had they not invested so much in the mammoth Voodoo 5 6000.
