I know these kind of questions are the worst, but I really need to get a good idea at how efficient two scenes are? I originally tried to build my UI entirely into one scene along with a game, and while it works, I’ve come across some issues that have made me think maybe two scenes would be better for this purpose.
Ideal is a game for the web, but as it stands right now my game performs at max fps in older iphone models (5,6,7). Is two scenes a heavy process in three js?
