The problem appeared a few years ago (I think around five). It only occurs in games running on the Unreal Engine (such as Fortnite, The Finals, Rv There Yet, and Polygon). Formatting the drive, upgrading to a newer graphics card, and updating drivers haven’t worked. I’ve lost hope that I’ll ever be able to play these games or future ones. I haven’t encountered anything like this anywhere else. I can’t upload a video, but I’ll describe the problem. In games, characters keep jumping around, as if they were reloading or something similar. This causes the character to fly all over the screen, making gameplay completely impossible.
