Just read at the Tech Report that the 64 bit version of windows is expected to assign 4 GB of usable memory (rather than the former 2 GB maximum) to 32 bit processes (e.g. like Poser 5/6 being run on Windows 64 bit edition). If this is true, and if Poser can use it, then it will effectively double the amount of memory that can be used without any need for a re-compiled version of Poser (or any other 32 bit app for that matter). Has anyone got a 64 bit PC with Windows for 64 bit (the latest beta release candidate) and 4GB or more of memory - and can you confirm this improvment does actually happen? Sadly I still only have a 32 bit PC, but I'd really like to know if an upgrade would be worth it. Regards and thanx, Jovial.
