Have you tried using RTSS or something to cap the frame rate at 60fps? That always seems to be the silver bullet for these sorts of issues.
I haven't and that's mostly because I'm a comfy couch gamer. If an operation can't be done with the controller, I rarely do it. In this case there's a few moments of stutter roughly every ten seconds. Annoying to be sure, but I'll live with it. Thanks for the suggestion though

Aside from a few technical hiccups this feels great.
