FullScreen = 0
The game executable has a hard coded memory limit of 1 GB, with large maps this can causes poor performance and crashes. As most systems have significantly more RAM in them, it is possible to expand that limit to utilize all available memory.
Download this executable and replace the RailRoads.exe file in the installation folder.
Note: Users with macOS versions prior to 10.14 can select the branch mac_retail_111 - macOS 10.13.6 or older only from the Beta tab on Steam. This enables the game to run with the legacy OpenGL backend on macOS >= 10.12.4.
