True, but I have read people saying its better than PlanetCoaster, so who knows. I rather give them the benefit of doubt since they seem to be listening here. PlanetCoaster has a different management and development team so yeah.
Every update includes minor optimisation upgrades but given that they have never addressed the limitations of Cobra my assumption is that there's only so much they can do. I imagine that at some point they will have to address it, because the more DLC they release and the more animals they add to the game, the bigger people are going to want to build their zoos.
