Of course it was a 64 bits compile. They are not idiots. they have a multi
billion dollar reason to compile it for 64 bits.

Rethink your statement!

Suppose someone from the testdepartment then tells his boss that the
billions of investments into their 64 bits cpu were shown a bit worse
because they only ran software in 64 bits.

How many seconds before entire testdepartment is fired?

0.01 if i was that manager.

Of course the testdepartment optimized the executable as far as they could
for the 64 bits processor. Anything that was possible until now has been done
let me assure you that.

The fastest executables with production compilers can be found at specint
of course. Only beta versions of copmilers which didn't make it into the
mainstream are possibly not allowed to get used for specint (which is
a good thing).

So if there is anything out there yet that allows to compile crafty to
64 bits somehow, be sure they used it.

Best regards,
Vincent
