I took some time today to do a little optimisation - primarily looking at commuter logic and navigation. Depending on your station, you might find some 30 to 40% improvement in your FPS in *very* busy stations. This is just for testing so let's see how it pans out. I made some other minor changes along these lines.
Let me know your experiences, and please do continue to submit maps that you have noticed performance issues on, as this is a great help for me in testing.
Beta 300:
-Altered commuter step interactions for less CPU intensive behaviour
-reduced action rate of PA and Fans
-reduced rate of object heat calculations
-refined max commuter limits
-tweak to map generation dimension specifications for more optimal experience
