I understand. And yeah, I've tried using borderless fullscreen mode with the 4K Higher Resolution UI option (in 1080p) and that definitely improved things! Except the fps is incredibly low but I'm not sure if that issue is with resolution or if it is more of a graphics card problem..? The FPS drops only occur when i put the game in fullscreen, regardless of borderless or windowed and it stays at 17-19fps at best.
It seems that once the game goes beyond a certain resolution the FPS starts to massively drop
