SGI's default microcode for Nintendo 64 is called "Fast3D", which some developers noted was poorly profiled for use in games. Although it allows more than 100,000 high accuracy polygons per second, this microcode is optimized more for accuracy than for speed, and performance may suffer as a result. Nintendo's own "Turbo3D" microcode allows 500,000–600,000 normal accuracy polygons per second.

照你这种说法，n64完全可以用低精度把PS秒杀，那些开发者何苦死死守着10万多边形不放。
