I've also run into this 1GB ceiling that only Vue seems to see on my xp32bit system. I can happily crank Bryce and Photoshop well beyond 1GB without any problems (bryce I can literally push up to 2GB and measure the point at which it will crash out).

Out of curiousity - do you have a dual channel ram setup on your motherboard - I do and am wondering if Vue is struggling with interpreting that.
