After updating to version 6 of Forest Pack, our studio has noticed a severe drop in the performance of using Area>Paint. After only a few strokes, it becomes too laggy and unresponsive to use as intended. We ended up using little hacks where we turn off the paint visibility, but that can only take us so far to ensure we can see what we are doing. I've tested this by opening a fresh install of max, creating a 6mx6m plane and a 5cm cube to paint along its surface - with all other settings at default. The issue arises after dragging the paint brush along the surface almost immediately. Is there any possible solution to this?
Our studio was on 3ds Max 2016 (which had the same issue) and has since upgraded to 2019 (formatted all machines) with no change. Our machines range from 40 core dual xeons to i9 machines with 1080ti cards, so the issue is not with our hardware strength. The version of Forest Pack is 6.1.2 and I've attached a screenshot to illustrate the simplicity of the scene.
Any help on this would be greatly appreciated as we regularly work with large vegetative scenes that require a lot of manual touch-ups for realism.
