Well, on my father's and my son's computer, there's a GeForce GTX 1050 2 GB + i7 7700K processor + 32 GB of RAM - it doesn't lag, but on my computer, it lags a lot, and on my laptop, it lags immediately! :smile25:
My laptop is old; it has an Intel Core i3-2310M, 3 GB of RAM, and a GeForce 315M.
As you can see, it's not even a gaming laptop.
Yours must be even older, or you might be loading a save file with a lot of stuff in it. Because, as I said before, I've tried it on different maps, both small and large. Yesterday, I even played on the "War of the Worlds" map with 8 players, maxed out all the heroes, and there were no lags, thank God!)))

The last two creatures. Both are low-poly.)))
I'll upload them in the evening. I'll check them again, maybe I'll reduce something for performance.
