Same i mean - memory leaking error
NO way to play.
Even at 1st turn

Plus, in some gog torrent trackers cracked version i saw description about the Patch 1.801 (29 March 2018)
(hasn't seen here that descriptions and... i mean i saw there maybe useful thing)

Added a workaround to allow people with high end PCs to run heavy mods. Especially mods that increase the number of figures - characters - on screen, such as the 'Regiments' mods.
Create a text file called 'Game.cfg' in the user 'Config/' folder of the game's user directory. E.g. '/Documents/My Games/AoW3/Config/Game.cfg' on Windows.
Using a text editor - e.g. notepad - add a line saying 'SHADER_SIZE=2'. This doubles the render call limit.
Please note that this is a workaround and not an officially supported feature. I.e. the game could become unstable and the workaround might still not resolve issues with many figures on screen.

i Mean i have official steam version http://prntscr.com/jf7ztg

but i (using win10) has no Game.cfg file in that folder.
Mean, i doesn't know, would it function help or not (i am not using regiments mod, but use Decadence, Map generation (more structures) mod and mod adding new water features. And can't try to see, would it or not.
Maybe in win10 it is stored in other place? or maybe not in docs folder, but in steamapps folder?
(i do see my game info and mods by the /Documents/My Games/AoW3/ path, so it works, and there Config folder, but no files there)
