Laggy feel to game (pc)

So I just wanna know if I am losing my mind or if there are more people who have the same experience as I do.

So I got a pretty beefy pc but the game feels as if there is a whole lot of input lag and just stuttery in general.. I tried multiple resolutions and multiple screens (it seemed much worse on my ultrawide)

At this point it feels as if there is deffinetly something wrong but can't seem to fix it. If anyone experienced the same or has a possible fix, please let me know.
