On my system (Intel 64bit which the program was compiled on) the 32 bit and 64 bit were the same speed. Past versions the 64 bit was a bit slower then the 32 bit. I have tried several times to get the same results with Fruit but the 64 bit is always just a bit slower. I have not been able to narrow down why this is yet. >>Higher Class: >> >>1.

I recently did compiles for Tord and a 64 bit version was created and it is faster then the 32 bit compile. By how much I don't recall. I have not seen source code for Scorpio so I can't compile it. I have always been open to help any author with fast compiles. Bryan
