My app is designed for at least an MMX based CPU, so I would like to add MMX to make my proggy faster. Ive tried my own alpha blending routine in C code, but its way too slow, and my game isnt in 3D so I cant really use the 3D card to do it (i know its possible, but why use 3D h/w just for alpha blending?). Is it possible to use MMX to do alpha blending? If MMX isnt possible, can I get an Alpha blending LIB/OBJ file (coded in asm) from somewhere? What does MMX actually do? Ive heard MMX is only really good for decoding/encoding video and sound, and manipulating multiple bytes of data.. aka, alpha blending! Maybe ill should look on Microsoft''s web page for some MMX routines? --------------------------------- -what is that wierd message icon i used?

A deck of cards.

(I knew my expertise would come in handy some day!)

I''m not sure about how to do the MMX stuff, now I''m rather curious myself. Which API are you using? I think I saw something in the DirectX docs about it...
