MSFS 2020 and stutters

No. It is a completely new program with a completely new graphics engine, wich I am running
at its native resolution of 4K with gorgeous textures and at 60 FPS solid fixed, which gives a perfectly smooth movement, as clearly seen in the video.
But as long as you don’t compare both sims side by side as I did it is difficult to understand exactly what I mean. Although I find the video, if watched properly @ 4K 2160P 60 does a pretty good job in order to achieve that.
