Depending on the performance of your computer you might experience more or less lag when performing certain actions (opening menus, placing blueprints, undo, etc.). This is a problem because time does not progress ingame while the game is lagging (guests don't move, rides don't move, etc.). Therefore, people with weaker hardware are at a disadvantage when speedrunning the game.

I made a comparison between a recent run of mine and the current record by NitroKuite.

As you can see there is a 1.43 second difference between the runs caused by lag (there might be additional lag frames i missed).

This is a difficult problem to address and I currently don't have a solution for it.

Over the past two years I've been working on a new auto splitter for SMO which uses neural networks to detect events like Moon Get, Kingdom Ends and Fadeouts. This eliminates the need do create split images like we used to with AutoSplit and makes the process of creating auto splitter routes much easier. Here's the website for it. https://github.com/LordAsdi/SMO_AutoSplit The source code is on GitHub. https://github.com/LordAsdi/SMO_AutoSplit
