After season start it have been bad, I reportet it was even bad before season start.
Today its almost unplayable, constant lag and stuttering. You attacks are delayed, and so are the graphic animation afterwards its like you hit, and there go a second before the game respond. So you play the game in small inches all the time move, freeze, move, feeze in every 5 seconds. What should have been a great season before diablo 4 is instead a mess like never seen before in its lifetime. I cant remember it have been running this bad before. Maybe once way back but still. I can to a point live with que times. But the performance is just bad and not fun at all.
My 90 year old granny, runs better than D3 atm.
