random stuttering/lag

hi ! i have been experiencing stuttering and slight lag when moving my screen in the game and zooming in and out.

i have a new pc with a great graphics card so that should not be the issue.

i just got this pc in april and this wasn't happening then.

im not sure what is causing this random stuttering. i have updated my game and mods. i even removed cc and it still does it. even in a new save file. 

i just capped my game in my Nvidia settings to 60 FPS

can someone help me in any way?? :-(
