game keeps crashing

was able to play the game just fine for 60h but after a sudden game crash the game became unplayable for me. it keeps crashing over and over again. i did everything possible on my end, repaired on steam, reinstalled, downloaded the ggg client, updated drivers...

when i start the game i get these weird artifacts flickering all over my screen, even in loading screens. sthis started happening after my game randomly crashed once 60h in.
