Oh, no, I was mistaken...

I noticed a pattern (at least in my case): after each new patch, the game initially starts to lag on almost every step in various places, but the more you play (so to speak, overcoming the thorns and obstacles, it's extremely annoying, but there's nothing you can do about it), the fewer crashes there are, and it continues until the next patch, then the cycle repeats.
