Can someone more familiar with the Intel side of things confirm that src/Game/KNITransform.c ("Katmai New Instructions transformation routines") isn't actually used by anything and can be deleted? Thanks.

Whoa... I don't know if Homeworld SDL calls that particular module but those are very important speed enhancements for 3d transforms.

Otherwise known as SSE, or now as SSE1 with SSE2 and SSE3 in play.

These were adopted by AMD as well... my AMD XP processor uses SSE instructions if available.

So the question is does HWSDL use this module or does it use the default SDL-OpenGL implementation of SSE... or does the code use SSE at at all? If not there's a considerable speed boost waiting right there for Intel/AMD processors.

If only I had a clue how... :)

Mac has no equivalent?

Ah, no, it is used. Relic haven't used a consistent function prefix for the module so it looks unused to the uninitiated. No robes of the High Priest for me I guess.
