Go up one level in this thread
I had done some testing a month or so ago against native builds and windows builds under wine and did notice in some cases the windows binary was faster. The only thing I can think of to explain it is the compiler. If you compiled a linux binary using gcc unoptimized it might be slower than a windows Intel CC super optimized build. Not sure how efficient MS's compiler VS is compared to gcc but that might be a factor to.. When I want an engine to be as lean as possible on a given system I compile with ICC (Intel's compiler which runs under linux) As for wine, running a windows binary takes a very minimal hit in performance. It creates a bridge between system calls for the most part. Josh P.S. What is CA7?

How can a win binary be running faster under these conditions? I >compiled the linux version with gcc 4.0.2.
