Have always turned this shit off. Also turn off anything Bloom or similar. And sometimes turn off camera shake too.

Lenses flare and motion blur are some of the first setting I turn off in any game.

Ah yes, let's put on the option that lets me see my game worse. I am very smart genius dev.

MY EYES ALREADY MOTION BLUR! THE GAME DOESN'T NEED TO ALSO BLUR!!!

I just launched Valheim again and disabling DoF and motion blur were both 'accessibility' settings. Rustled me jimmies good.

It's also completely unnecessary. Motion blur is already a product of your brain not being able to keep up with your eyes and you'll get a more natural motion blur without adding fake motion blur when the motion is fast enough.

Motion blur and head bobbing are the worst

It's IMO not the effect itself but how it's used. Way too often game devs use it to mask low FPS and visual artifacts of incompetent graphic pipeline (usually Unreal Engine)

The first time I encountered motion blur was GTA 3 for PC back in like 2003. It was awful so I've turned off motion blur on every game since. I have no idea why it was around then or still around now.

Good motion blur is actually pretty decent but games seem to always use shitty implementations, had to use reshade for it

It's like cool, I'm at home and playing video games drunk and my computer is also drunk.

Motion blur is great in racing/driving games, but that's largely it. BeamNG.drive added it a couple updates back and it improves the looks a lot in my opinions. Makes speed feel actually fast.

I really liked when the screen would blur if you were suppressed in bf4. Really made it feel intense and actually gave you a reason to pin down someone with an lmg.

I just don't understand why it is usually on by default.

If your character is drunk, drugged, or otherwise impaired, yeah load up the motion blur.

Besides that, I don’t get why it’s there. Stuff just kinda naturally blurs when you turn fast if your eyes can’t keep up. If your eyes can keep up, why would you want it blurry?

My little opinions. There are nuances and in some cases I could prefer enabling or disabling a feature, game by game basis. A plus and minus sign in front of the topic is a general conclusion if I like it or don't. You workout what plus and minus means here.

+Motion Blur: Looking at Motion Blur in a static image is unfavorable to the effect, because it's an effect that makes only sense to look at it when moving. And there are different implementations of Motion Blur, sometimes making the experience better, in some other cases it makes it worse. I quiet like the effect in racing games, when used correctly. It increases the sense of speed and has no downsides. I do not like it in first person shooters. A good implementation knows why it is implemented and does not blur the entire screen for no reason, and the blur quality is good. So it depends, but I like good and useful blur.

-Chromatic aberration: I hate it. Coming from photography, chromatic aberration is an artifact that decreases the image quality without gaining anything. This is usually a weakness resulting by the camera lens. In a game, I get that they try to emulate filmic experience, but outside of very cinematic cut scenes that look like a scene from a film, I don't see any benefit. It's often also used in normal gameplay of action shooter games in example. It just decreases the image quality and perceived sharpness. I hate it. I hate it like sand, it gets everywhere!

+Depth of Field (also known as DOF): I like it. Also coming from photography, the depth of field is a useful technique to bring something in focus. The background be out of focus, so it is less noise. Whatever is in foreground you want to bring attention to, is the main subject and sharp. This is cool effect used in cinema, photography and therefore in cinematic cut scenes in games that look like a film. There are couple of games that use it in gameplay too, but I never liked the look of it (in gameplay). I guess there might be exceptions, like for certain single player sniper games. Overall I like the effect when done good and usually have it enabled.

In some games these effect can cost additional performance, so if that is a critical issue, then I would disable them all probably.

Per-object motion blur is great but it’s a lot more expensive than a screen-space postprocessing effect.

For me, film grain is the worst. I first came across it in Left 4 Dead and I remember thinking "wtf is this trash?"
