Hi!
I work with the new displacement fix for 2 days now and till today I had some very good performance and no issues with parsing time.
But, today, while working, I merged a couple of new tree models in my scene and the problem appeared again. Actually, turning off Displacement got only a bit better. Something happened and it slowed down all the parsing process....
I close 3ds Max, open my scene again and the problem disappeared.
Just to let you know even if I know that is not too much info for you now.
Thanks,
