As someone with literally thousands of hours in RCT 1 2 and 3 combined this looks genuinely awful to me.
OpenRCT2 (RCT2 Mod) has better animations and most likely more quality of life features. Really RCT1 looks better and smoother than this and it did so on a pentium 4 CPU in 2003.
I don't understand how a 24 year old game is making this new one look so awful. To be fair, Chris Sawyer captured lightning in a bottle for the first game, but come on! You're telling me a huge studio with millions of dollars and tops of personnel can't do better than this?
Yeesh.
