is a little useless; it's it quite obvious that the start of the function/subroutine is right there.

However, the rest of your comments are very detailed and very well placed.

Don't use dec; using sub REG, 1 is faster.

dec runs in 1 CPU cycle. sub REG, 1 runs in half a CPU cycle.

Other than that, I'm not too familiar with xmm registers and the instructions that go with them.

However, as I look into them, if any improvements pop into my head, I'll update my post.
