Quote - In win7 you can use readyboost to supplement your ram if you don't have the means to buy more ram. This means use a fast usb drive to supplement your ram. If you do have the means do upgrade your ram and operating system to win7 64bit to work on complex scenes and have multiple programs open in a bridge.

32 bit can still only address no more than 4GB regardless, even on a 64 bit computer, running a 64 bit OS even if you have 8TB of RAM. Bryce can only address 2 GB of RAM and if you open DS from Bryce, that still has to fit within those same 2GB. Windows will spool and use that full 4 GB of RAM, presuming it has free HD space.
