Game itself runs a bit slow, but it's still in active development so it should, hopefully, run better as the updates go on. The devs do post optimizations that result in performance gains in their patch notes and some of their monthly dev updates that they post on steam. So I'm confident that it will improve. I get about 90 FPS on a small sized park with 64 animals and 1154 guests. Only GPU modification is setting my 9070 to a power limit of 245W with LACT.
