Hey guys, I've started making some config.tabs and pushed the game... Then I found several glitches regarding time acceleration which you may not be aware of:
As I developed my own config for Simutrans 64, on Steam, the issue arose that I could never get the game to fast forward faster than around 150x, that is despite putting numbers up to 25k on the config file. At first I thought it was an optimization issue, but my CPU is only being used around 10%, and so I decided to try and hold "." to speed up the passage of time and eventually reached speeds of 750x without a hitch. Therefore I assume that, somewhere in the code, is a cap on how fast the Fast Foward button goes. Could someone confirm and, if easy to fix, remove said cap from the game?
(edit: it should be noted the 150x cap happens regardless of map size or complexity and is independent from frame-rate)
Another interesting issue regarding time is that when accelerating time using "." vehicles start breaking speed records at ever increasing pace; In fact, I had several vehicles go some 40% or more above their max speed, such as a carriage team making 36km/h!
Hopefully, that rounding error can also be addressed in a future update.
Hope this report is useful, thanks for developing such a fun game!
PS: here are some images to illustrate:
