you don't neccesarily need to recode. sometimes just a recompile to a
64bit binary with the right compiler flags will boost you without
changing a line of source (assuming you didn't hardcode yourself into a
32 bit environment with your pointers).
Also, JIT compiled languages such as Java or dotNet (c# etc.) will also
just go faster as long as the JIT engine installed is a 64 bit engine
that compiles to 64 bit code. No recompile of your software required.
XSI is neither. But the latest MS Office is actually largely dotNet and
will get a speed boost. Which is kinda funny... given that MS Word is
the last program I can think of that would actually benefit from a 64
bit execution environment.
As far as the actual speed boost goes, Its a bit contentious. Intel was
arguing for a long time that they had already extended their 32 bit
processors to have some 64bit lengthed registers to process floating
point numbers of such magnitude in one instruction. And hence, they
argued, no need to go 64 bit. But its really tough to sort out the fud
from the marketing from the truth. So in the end it'll probably end up
being a benchmark war. We really need to get some good solid XSI test
scene benchmarks btw. I've not seen any. And they can really be useful
for sorting out the reality of all these hardware configs. Mental ray
performance is one thing but I'd really like to see some scenes that
test out XSI's vertex processing in viewports.

Yeah that's what I kind of thought, just moving to 64bit wont make
anything faster unless you code it to take advantage.
If you read some of the stuff out there it's almost as if just sticking a
64bit clip in there magiclly increases your speed tenfold! Grr! Marketing!
Grr!

Hi there,
Just a quick question as I don't fully understand all this 64bit stuff.
I understand that moving to 64bit allows extra memory, but why will
moving
to 64bit make xsi any faster?
Regards,
Simon
