[2019] Frame Stuttering

(Question) Is anyone else getting frame stutters? I get a constant 60fps at 1440p with everything on max bar a few shadow settings and volumetric fog, but every 1-5 seconds I get a frame stutter. Only started happening after I reinstalled my Nvidia drivers to try and resolve a weird light artifact issue I was getting. Iv tried lowering all settings in game and in the Nvidia Control Panel with no change. Iv tried rolling back my gpu drivers to the one before the latest. I’m stumped!
