The viewports dramatically affect the resources. Use this knowledge to help keep resources at a safe level. I watch the PF useage in the task manager and purge my memory when the PF reaches the 1.5 gig. After a second or two the PF drops down to 400MB. The vue resource % may not be accurate. This update is a step in the right direction. I been working with vue final's last update and I wouldn't dream about going back to the prerelease. There are too many things that work better for me to do that.
