I'm not building levels as I should, actually I've just built five prototype levels. Procrastination and the lizard brain, I guess, as I'm only making things worse for myself. This means I have to build all say 40 levels in a row, without much programming intermission. Gaaah! Human dumb! Currently I'm optimizing a bit, apart from third party code (sound and physics engine on the PC), these are my worst offenders before optimizing:
The timer you might wonder. Yeah, I'm doing system calls all over, easy to fix. The shadow volumes I'll have to rewrite and the vector/quaternion stuff I can probably manage at a higher level by not calling or precalculating.
