I tried with openGl off & on - I only got from a 42-46% increase with still a crash...also had background draw off & undo's at 1...FYI.

Herein lies the problem - you load the item resources drop  - delete the offending item - purge the memory - you get nothing back...in fact when I tried at 1 point, Vue crashed while purging the memory :(

Also another keypoint - it works in V5I, smooth as silk :)
