Does anyone know of a simple tutorial for optimizing for 3DNow and SSE? I found a little package that has the classes and stuff that I need, but I''m waiting for a CD before I install it. In the meantime, It would be nice to see how practical it is to use.

Depends on what you are doing... remember that your OpenGL drivers already use it to do stuff if they are worth their salt. So a lot of Matrix math is probably better off in the OpenGL libraries these days between driver optimisation and hardware T&L.

Then again, you''ll have to be pretty strict about when you do those things.

In addition, Intel has some good code examples on their developer site for MXX and SSE instruction sets
