If you want a clear image you have to go to your post processing volume and disable motion blur by enabling it and set the amount to 0 (weird but I guess there is default post processing values without post processing volume and the presence of a post processing volume overrides them), make sure that in ‘scene color’ fringe intensity, vignette intensity and grain jitter are disabled, or set to 0, if you want an even clearer image, in ‘misc’ set the AA method to ‘none’ (careful then, by doing so, some reflections will not be calculated, the issue is going to be fixed though)
Hope it helped ! Let me know !
