someone asked about sse a bit back - I think sse2 will get the same answer..

Currently VRay doesn't use SSE instructions for compatibility reasons. The last time I tried to compile it with the Intel C++ compiler with SSE instructions enabled, the resulting code was slower than without them. There have been many new version of the compiler so it may hande SSE code better now, however judging by other projects I've been working on, SSE makes very little difference in speed (usually the code is a little faster, but there have been cases when it's actually slower). In addition, SSE instructions reduce the precision of arithemtic operations - everything is computed in 32 bits instead of the normal 80.
