One thing I'd note, is, you have a 240hz monitor, and get around 70% gpu usage. Can assume if you divide by 4, that would be a more common result (so around 17% gpu usage for 60hz monitors).
Maybe performance is fine but is struggling to render so quickly!
To lower gpu usage overall, be mindful of any effects you use. You could also make a "quality" system by using System>Set Canvas Size, where you'd get a blurred result but allows people with weak GPU's or high refresh rates to be able to get a more stable FPS.
Your cpu seems pretty good for 240hz.
I'd recommend switching your refresh rate to 60hz to observe performance, so you have good idea of what most people would experience.
