I have a great idea for players with huge parks like me. I currently have 36,000 guests. As you can imagine the frame rate is horrible. So much in fact that I find myself pausing the game anytime I need to build something since it'll run faster if I pause it. But I digress. The idea I had was enabling lands/different areas of the same park. For example, I have about 9 different lands in my whole park. Instead of loading the entire park, just load one land at a time. Then when I want to traverse to a different land, there could be a portal option on the arch pieces that will close the land you're leaving and open the next land. That way, 1 - I keep the same number of guests, 2 - the transport rides would still be able to cross between lands, 3 - the frame rate would be as intended since I'm not loading the entire park all at once.
