Quote - This uses sse2 so it wont work on my computer.

Damn, I never thought that it would be a problem, any some years old computer has SSE2.
In only one part of the software I use a SSE2 routine that has a tiny advantage over the previous SSE that still exist commented, I forgot to compile and put back the older SSE routine.
SSE2 in theory looks great, but in practice have very little advantage, if any, over the classic SSE/MMX..

Stupidity also evolves!
