Stuttering even on cinematic and options screens

Running an i9-7900X, 64 GB RAM, Maxwell Titan X and experiencing stuttering issues on every non-static screen. Even the animated window tiles in the main menu that play when you hover over them stutter. They play smooth for 1-2 seconds then 3-4 fps, then play smooth again for a second, then 3-4 fps etc.

It happens in game even at low detail at 720p. But I don’t believe it’s a performance problem because the animated cinematics do the exact same thing.

I’ve also tried the focus switch problem and it isn’t that. Is anyone else experiencing similar problems?
