My system is a 3.6 GHz Intel P4 with 1 GB DIMM and an ATI Radeon 9600 running under Win XP Home with SP2. I have Vue 5 and the latest update from e-on installed. When I open Vue 5 everything works perfect. After a few hours of adding and moving stuff, Vue gives me a low memory warning. The bigger the scene gets, the faster the low memory warning shows up. While this seems logic I can't understand why I get this warning with scene files of only a few MB. I couldn't add any more stuff at a scene file size of only 95 MB and approx. 7'500'000 polygons in my latest image and I think there should be plenty of free memory with 1 GB physical memory! Turning of background drawing improves the situation although my ATI Radeon 9600 is definitely on the compatible graphics card list. Will buying more memory help? Any hints appreciated!
