Hello,
So me and a friend noticed something while playing multiplayer.
Over time Grim Dawn eats up memory which results in massive FPS drops, but ONLY for the one who JOINS the game.
The host does not have this problem.
We mainly noticed this in Crucible.
e.g.
memory usage when game started (it usually hangs around 1-1.3 GB)
memory usage after playing a bit
And it just keeps increasing.
Restarting the game fixes it.
