I've read in many old 3D graphics tutorials that fixed point math is a lot faster than floating point math, but I also read in a more recent document on pentium optimizations that the FPU can do most floating point operations in one clock cycle, so I don't know what to believe. So I turn to the Cboards with this question...is there any performance boost to be had out of spending hours implementing fixed point math in my 3D engine, or is floating point just as fast, or even faster? I don't want to spend a ton of time on something that isn't going to make anything faster...
