limit your fps to 35 in nvidia control panel. This actually increased my bottom end fps and got rid of pretty much all stutters. I’m on 10500k @4.8 all core and stock gtx1080 at 1440p on pretty much max settings except texture super sampling which is off (no noticeable difference between any of the settings) Without limiting fps I get anywhere between 30-55 with a lot of microstutters. Limiting to 35fps, I get 35 fps everywhere, in any plane. even NYC. My CPU and GPU usage also matches yours at ~25 and 8 to 10 percent. This is why people with 3080s and 90s are not seeing any difference. the Gpu is doing almost no work to begin with. (it does however make a huge difference in VR… but that’s another topic) I often watch movies on Amazon while flying and that is more resource heavy than MSFS. The only way we will ever see better performance is with better coding on Asobos end…
