Bad effects are bad.
I used to hate film grain and then did the research for implementing myself, digging up old research papers on how It works at a scientific level. I ended up implementing film grain it in Starfield Luma and RenoDX.
The gist is that everyone just does random noise which raises black floor and dirties the image. Film grain is perceptual which acts like cracks in the “dots” that compose an image. It’s not something to be “scanned” or overlayed (which gives a dirty screen effect).
Related, motion blur is how we see things in real life. Our eyes have a certain level of blur/shutter speed and games can have a soap opera effect. I’ve only seen per-object motion blur look decent, but fullscreen is just weird, IMO.

On Motion blur, our eye’s motion blur, and camera’s shutter speed motion blur are not the same. Eyes don’t have a shutter speed. Whatever smearing we see is the result of relaxed processing on the brain side. Under adrenaline with heavy focus, our motion blur disappears as our brain goes full power trying to keep us alive. If you are sleep deprived and physically tired, then everything is blurred, even with little motion from head or eyes.
Over 99% of eye movement (e.g. saccadic eye movement) is ignored by the brain and won’t produce a blurred impression. It’s more common to notice vehicular fast movement, like when sitting in a car, as having some blur. But it can be easily overcome by focused attention and compensatory eye tracking or ocular stabilization. In the end, most of these graphical effects emulate camera behavior than natural experience, and thus are perceived as more artificial than the same games without the effects. When our brain sees motion blur it thinks movie theater, not natural everyday vision.

Yeah, if you see motion blur in real life, that usually means something bad, yet game devs are not using it for those purposes.

Eyes do have a “shutter speed”, but the effect is usually filtered out by the brain and you need very specific circumstances to notice motion blur induced by this.

No, they don’t. As there is no shutter in a continuous parallel neural stream. But, if you have any research paper that says so, go ahead and share.

It has nothing to do with a neutral stream, it’s basic physics.
