I recently obtained this XFX RX 570 8GB used, and have had it perform very well until yesterday. Yesterday, I noticed that a few of my games were not running as well but I thought nothing of it. Today, I found that War Thunder, a game usually running at around 100 fps was struggling to run above 50. I restarted hoping to fix this issue but found that War Thunder instead got worse and struggled to even reach 30. Yesterday, Windows apparently installed KB4503327. Could this be causing issues with my card or drivers or is my card faulty?
