I made a HUGE performance improvement to my Tycoon.
Without removing a single asset, I went from an average of ~2,500 draw calls to around 800–1,000, gaining roughly 35% more FPS.
The tycoon has around 23K actors. Even with aggressive use of HISMs, I can’t really reduce the actor count much further.
I’m also getting around 180 FPS with UEFN open, Nanite enabled, and everything set to High (although I’m not looking at a particularly heavy scene like one where all the plots are visible), so I’d say that’s still a pretty good result.
I spent a lot of time optimizing material slots, HISMs, light rendering, collision complexity, LODs, textures, and more.
I’m pretty satisfied with the result. Keep in mind this is a Tycoon with a huge number of actors, not a 1v1 or a simple map with just a few assets.
