I’ll add a few observations of my own. While Bryce works with 2GB, there are cheats you can use to free up some memory. Starting in Win 7 you can have completely user controlled amount of ram added by using SD card and or flash drives, dedicated to power boost, which dedicates the drive/card completely to ram where it stores your most often used programs in memory, freeing up main ram space. I have a Dell Inspiron 6 GB which runs almost 40-50% ram. I got out-of memory errors at 51% memory, before plugging in and configuring the SD card (2 GB) and flash card (16 GB). Now my ram can go up to up into the 70’s because a lot of Bryce functions are being run off the expanded drives. This is a great help when it comes to rendering large scenes, especially DAZ-populated scenes such as my resort scenes of people lounging around the pool, sitting at picnic tables and diving in/climbing out of the water.I’m still using Daz 3.71 because for some reason DAZ 4 doesn’t run on my system. I use DAZ to create, pose and import figures into Bryce, I don’t use DAZ for itself. It would follow even more memory would be freed in the process of transferring figures from DAZ into Bryce if you used the 64-bit version of DAZ}Studio. If you work it right, you can expand the working space of DAZ and Bryce by allocatingsome functions to the card/drive and others to main RAM. Oh, LordHardDriven, thank you for the link above… I am so all over that
This will only speed up bootup and data that bleeds off to the page file on disk is bled off to the SD card instead - which is a huge time saver. You’re referring to Ready Boost, This is no memory expansion as such and Bryce cannot use it, as no other program can - and Bryce does everything in memory and never uses the page file (unfortunately). I fell into that trap a fortnight ago and lost an afternoon testing it out after visiting http://www.ehow.com/how_4969220_make-card-work-like-ram.html - until I searched Microsoft for Ready Boot and got wiser.
The only temporary solution to the 2 GB limit is at the moment to make Bryce large address aware, as lordHardDriven says above.
