OTOH then you will be comparing how efficient those systems are at
running 32-bit apps. Is that really the goal?

Don't; that's not how newsgroups work ;)

I'm currently compiling beta 31 for Win64. Could I have the POV-Teams
permission to release this build, since it's only available for Win32?

Just to ensure that it gets said; yes it does, yes it is, and thankyou. :)

I'll try to get one built. The issue for me was the boost libraries, this isn't
difficult to fix, just fiddly.

As I've noticed. Though I've managed to compile all POV files for 64
bits, I can't link the final .exe because I can't convince Boost to
build 64 bit libraries.
Grr...

Chris and Chambers,
Thanks a ton for looking at beta 31 for me. I was able to get a hold of beta 30
from a kindly user, so I'll be able to include POV-Ray results, although they
are slightly outdated I suppose.
Just to add a comment on 64b vs. 32b performance, the major differences:
1. 16 registers vs. 8
2. 64 bit pointers vs. 32b pointers
3. >4GB of memory
2 is a subtle point - it substantially increases the pressure on caches and
TLBs, since cache lines are fixed size (64B).
