And this is expected as well! You can’t fully eliminate these with the current motion smoothing implementation.
However there are ways to make it much much better, but AFAIK FS2020 is not using them nor can it be using some of them because of the limited OXR API.
I’m particularly thinking here in feeding the OXR driver with the depth buffer, and hinting the NVidia Optical Flow lib with the pixel motion vector texture:
