That's why I was so surprised! I've heard of early PCs omitting floating-point, but it seems crazy for a platform designed specifically for games, for precisely this kind of reason.

That's not the reason, though.

It seems so. A recent video about the graphical quirks of the PlayStation:

Why PlayStation 1 Graphics Warped and Wobbled so much https://youtu.be/x8TO-nrUtSI

The reasons mentioned in the video have nothing to do with the warping and wobbling, see what i wrote on Reddit about it: https://www.reddit.com/r/Games/comments/fnl0o1/why_playstati...

Yep. 16 bits isn't enough precision for 3D no matter how you use it.

When you get up to 32 or 64 bits, fixed and float are both very good.
