Hi EiffelPower75,
Thank you for reporting! I’m sorry this issue has spoiled the pleasure of playing it.
Because it’s an (oldschool) 32bit game it will run on just thread with limmited memory for being stable. Try playing the game with 1080p, medium/high graphic settings, and close apps that take a lot of recources (other games, video capture apps etc) - this may help with the stability.
