No, they simply are more instructions for you to use. You *do* have to
add some logic for fallback routines though. This usually comes in the
form of a function pointer. 3Dnow! and SSE are even more interesting
(MMX does only integer, 3Dnow! and SSE can do FP).

I am not sure from memory, but I actually think that BG2 will *require*
a 3D video card, much like Q3A (i.e. there is no software renderer)!
