I loaded a pretty heavy file in Max 2019. It has 4.8 million polys, lots of Forest Pro plants, Soulburn scripts in use, Relink Bitmaps loaded and a few other scripts active.
With the switch both "on" and "off", I see no difference in my FPS, interactivity fluidity in viewports, nor menu interactivity speed. I use a Space Pilot to navigate and am getting 3.1 FPS in a viewport with all 4.8 million polys visible. That doesn't change regardless of whether the switch is "on" or "off."
I'm glad that it helped @Anonymous . He did say he realized it might not be a solution for others. I currently don't see any difference but the next time I have a noticeable lag in Max 2019, I'll switch it off and see what happens. Right now, I just can't produce a lag that seems out of the ordinary as the low FPS I have right now is sort of typical for a file the size I'm using.
