He he he możliwe, że tak było (za czasów V5500 i niedoszłego V6000 to już na pewno było "fill rate is the king" xD). Chociaż do Voodoo 1, 2 i 3 "framerate is the king" też pasuje. :D

Z tym kolorem V3 to sprawa była dość zamotana, pozwolę sobie zacytować Wikipedię aby nie przekręcić czegoś znowu... xD

"Much was made of Voodoo3 (christened 'Avenger') and its 16-bit color rendering limitation; this was in fact quite complex, as Voodoo3 operated to full 32-bit precision (8 bits per channel, 16.7M colours) in its texture mappers and pixel pipeline as opposed to previous products from 3dfx and other vendors, which had only worked in 16-bit precision.

To save framebuffer space, the Voodoo3's rendering output was dithered to 16 bit; this offered better quality than running in pure 16-bit mode. However, a controversy arose over what happened next.

The Voodoo3's RAMDAC, which took the rendered frame from the framebuffer and generated the display image, performed a 2x2 box or 4x1 line filter on the dithered image to almost reconstruct the original 24-bit color render. 3dfx claimed this to be '22-bit' equivalent quality.[3] As such, Voodoo3's framebuffer was not representative of the final output, and therefore, screenshots did not accurately portray Voodoo3's display quality which was actually much closer to the 24-bit outputs of NVIDIA's RIVA TNT2 and ATI's Rage 128."
