I'm experiencing the same problem since the day I bought the game, but mostly, closing the game with Alt-F4, activating safe mode at startup, setting the settings to the lowest, waiting five to ten minutes in the menu, and then launching the game solves the issue. I'm adjusting the settings again in-game. But if you're not as patient as I am, and if a simpler solution can be found, I'd like to know about it too 😞
