On the The GameAgent blog we can find an article about porting Star Wars The Force Unleashed Ultimate Sith Edition on mac, from the console version code : dispatching on a fewer number of threads, rewriting of code based on permute (not available on Intel SSE), in order to use more common vector instructions.
Indeed, contrary to G4’s Altivec, that manages permute since 1999 (PS3’s Cell processors also include Altivec), Intel won’t provide similar vector unit until next processors generation (Sandy Bridge), that will bring AVX.
