Very cool. For Winquake, even fewer iterations might be accurate enough. I'm going to look up DP sqrt to see why it's better...

n<1 returns n. Should that be if (n=1 || n=0)? Could it calculate the sqrt of 0.4 for example? Maybe there is no case in Quake where it matters.

DP's is better because it's using an engine builtin. sqrt is a native hardware op these days so emulating it in QC is never going to be as fast.
