Extremely noisy image

This is how it looks :

I made sure to disable all effects with innate noise ( Distance fields, Lumen, TAA/TSR ) and this is while it looks less noisy, you can clearly see there’s still a lot of noise up close : Imgur: The magic of the Internet

There’s no post-process effect and screen resolution is at 100%, it also happens on empty maps and in standalone, I have deleted cache, all ini’s, updated drivers and even tried on another computer.

While it can look as passable at times, the video host’s low quality is severely smoothing out the harsher flickering, i simply cannot ship my game like this.

Basically, i’m desperate for help. Thanks to anyone who shimes in.

What are you using for anti-aliasing?

3

TAA, But all other methods have the exact same noise, and it’s still present without anti-aliasing.

I suspect TAA and TSR try to smooth-out noise in vain making it look much worse, but it does not come from the anti-aliasing.

4

You can flip through the various debug views under lit to try to figure out where the flickering is coming from.

5

Yes, but the flicker is present under all those, even reflections.

6

That sounds like a bug, might you want to try updating your drivers?

7

As previously mentioned, I already tried updating drivers to no avail.

8

After more investigation, the problem really does occur in all of the main view modes ( except for wireframe ).

Even unlit shows a tiny bit of jittering on certain surfaces, with the reflection view having the most glaring issues, here’s what it looks like

Again, i really appreciate any help with this, it does not need to be a solution, even suggestions will be of assistance.

9

It almost looks like it’s doing jitters for temporal AA without having it on, which is definitely weird.

10

I’ve never seen anything like this before. Out of curiosity, what’s your shader model setup?

11

I can see some Lumen (or maybe TAA) artifacts overthere. To fully disable it, you need to delete your Defaultengine.ini

Try it and tell me the result, please.

12

SM6, but SM5 is identical

13

Deleting the engine.ini seemed to lessen the jittering, but it was still very much there. But when i added distance fields, the issue was visibly the same

14

Yeah, that’s another thing. I would think about anti aliasing too, or maybe a low resolution in viewport (check the screen percentage) or low scalability settings.

15

Happens with scability at max/min, no anti-aliasing, screen res was at 100 or 140 on all the videos i uploaded.

16

Definitly not a me thing, looking at recently released Unreal games, this same exact type of noise is present

For example, Payday 3 : Imgur: The magic of the Internet

Later confirming with a friend, the noise is present for them too. Playing Remnant 2 without upscalers also showed this same exact noise.

At this point, i’m assuming that this is in fact an Unreal Engine issue, the only way i’ve been able to further reduce this noise was to implement FSR2 in my project with heavy tweaking, but this inevitably sacrifices fidelity for the sake of working around this problem which shouldn’t be there in the first place.

Would love for Unreal staff to chime in on this problem.

You can submit it like a bug. Better is you can also provide a very simple (as much as you can) example proof project:
