Missed this line. No, you determine if a function that is written in 
C/C++ could be better optimized by hand because of assumptions the 
compiler makes, then rewrite the under performing part in ASM. Thats an 
extreme case that rarely happens these days, but still does.

Do you write all of your logical operations on individual floats & ints? 
Personally, I like to use SIMD where ever possible, and I think this is 
a more accurate argument than just ASM. Particle effect systems are a 
particularly nice case argument here.
