When the artifacts appear the whole system freezes and a restart fixes it or sometimes if i let it be, the game crashes and im back on desktop and the game starts up again fine, it occurs again after 5 or 10 mins in game. Normal use like browsing or watching videos never gives me these artifact freezes.It's days are counted man, but if it still is running although with artifacts you can try lowering it's core clock by 100mhz and she how it works. If you have messed with memory clock, reset that.
