You can set motion blur to none on my end. Also left sharpness on default 45 for now myself.Ah I've left the sharpness on default which I think is 45, all other gfx settings are on whatever the highest they will go, so Ultra Ray Tracing where applicable and motion blur set to low as you cannot turn it off it seems.
What is your CPU and GPU there btw? Your frames look reasonable although I seem to be pulling 15-20fps more on average but that may be down to CPU differences as I'm sure I recall you had a 3080 Ti?
