I can easily max games on my 720p resolution monitor. On vanilla Skyrim, I either have 60fps with stuttering that is VERY noticiable, or lag spikes that are really common. I have a i5-4440 CPU paired with my 390. None of my CPU cores go to 100% and for some reason my gpu usage is REALLY low (usually stays at 0 and spikes to 10 at times) My drivers are all up to date (16.3). How can I fix this annoying stuttering?
