the question is that I am creating a forest map and when putting the trees the fps go down to 5 and 8 with a nvidea 1080, when trying to improve the optimization with the option merge actor does not leave me, are there other options?
I have the same issue with Megascans trees on a GTX 1070. Open your desired trees and only allow the worst LOD as minimum. It made no FPS difference for me, but it says it makes a major difference.
