What is it that adds this? I’ve also noticed it in a lot of modern games like Cyberpunk.
Looks like ambient occlusion with some sort of dithering filter.
Yeah seems like a side of effect of relying on “fake optimization” techniques like dithering assuming they will be hidden by blur passes like upscaling and/or TAA.
You’ll see it in places like hair and grass too. Stuff will look dithered if you turn off TAA, upscaling, or other effects that turn the screen into an unfocused blur.
