Sorry for skipping that info. I did the tests a few months ago and the compiler version was 3.2-4. I did compile with SSE. It said there was SSE support (not for AMD explicitly). Was I wrong? Is 3.3 actually out? When did it come out? Sorry to misinform people as the version 3.3 may provide more performance over the one I tested.
