Re: Carrara for 64 bit Windows 2005-05-09 - By pmiinalainen

For certain reasons, i have been following the 64-bit developments
quite closely. Drivers are indeed widely available for most common
computer parts.
What people don't usually realise, is that 64 bit doesn't mean
everything is suddenly twice as fast. Even 16-bit program can do some
tasks faster than their 64-bit counterparts . There are lots of
variables in the speed equation: programming language, skills of
individual programmer, knowledge of the platform etc... (I once tested
a3d application that was completely coded in assembly: the
funcionality was quite limited, but what it did, it did with
unbelievable speed. No need for more bits there) The latter two will
be fully utilised only when the platform starts maturing and
programmers get some experience on using those 64-bit advantages.
Currently, most of the available 64-bit application tend to be bit
slower than 32-bit versions.
For 3D content creation, 64-bit OS has some immediate benefits (after
recompilation, of course). The direct address to huge memory space is
propably the most important. Does anybody feel that they have too much
memory in use with Carrara? Other benefiting areas are database, file
compression, image manipulation, video editing and effecting. So, many
people on this forum might want to migrate to 64-bit sooner than your
avarage guy using microsoft office...
But when 64bit carrara ships out, i'm confident that Eric's gonna ship
and armada of wicked 64-bit versions of his plugins! He he... You just
told us that you're hardware is ready to go. So, no excuses there ;-)
