Command line: -YR
Description
Normally, TTD refreshes the map windows every 64 "ticks" of the simulation engine, which is approximately every 2 seconds. With this switch, you can choose the number of ticks between map updates, as low as 1 tick per update (the default with "maprefresh on"). Low numbers use a lot of CPU though, so only use them if you have a fast computer.
