I’ve tried probably a dozen environments available at the marketplace, even with those that claim to be very well optimized I can’t get more than 30FPS in a decent mainstream machine, 1440p, epic quality, this is by just spawning grass and trees, the FPS drop from 120 to around 30 in most cases. Nanite seems to have even worse performance. All these products have LODs, culling, etc…so I don’t know.
It makes me wonder if worth it to keep wasting time and effort on something that won’t be suitable as commercial product, even if I manage to complete the game.
