Hmmm... I understand but it's hard to get away from the maths on this one.
How can a scene that uses only 10% of my resources in Vue 7.51 all of a sudden need 70% in Vue8.

That's a pretty freaking big difference.

If I launch Vue 7.5 and 8 one at a time to see how much resources I have free when no scenes are loaded, there is only an increase of 9% for vue 8.
