Game too laggy when mining

Hello!

I currently use Steam Deck to play. I have noticed that the game lags a lot when collecting items and drilling through the blocks of the mines. It freezes a lot and it's unbearable for me which is a shame, because it's a very neat game otherwise. Is there something I can do? I already tried to low the frame rate to 30, disable shadows, etc but to no avail. I suspect that it's the counting of the items that is slowing it, because a lot of them drop during drilling and updating the total seems really slow.
