All fullscreen applications display immense input lag and low FPS

Question asked by raxyz on Jun 16, 2020

I don't know what else to do here, playing titles like PSO2, Gwent, Ultrakill or Gloomwood will always result in immense lag, and my rig is WELL above the recommended specs for each of these titles. Exclusive fullscreen or borderless fullscreen does not matter, when it gets fullscreen these games tank the performance to oblivion. Tried tweaking several settings in each game, the only thing that "stabilizes" the framerate is playing on windowed with no external software to turn it into Borderless fullscreen. What's wrong here?
