Hello,

as i understand there is much of growth with much trees, but it slows down a large map significantly. (as i have marture map where i try out mods and such)

The growth factor seems to be capped to 216000, is this possible to have a larger limit ?

Maybe other possibility is making growth calculation faster not for every tree, just make it for every chunk or area of the map.
As growth will be constant for all trees (save considering highend CO2 levels ) i think this would be a shortcut to check.
( if this is the case)
