DLSS Black Pixel Artifacts on Transparent Materials

I’m developing a game using DLSS 2/3 and Unreal Engine 4.26. I’ve noticed that these black pixelated artifacts show up on most transparent textures like skyboxes and fog. Only shows up when DLSS is enabled.

Is there any info about this and how to avoid this issue? I couldn’t find this issue on Google. It looks like a pattern of some sort.

Hi @kabassmusic, welcome to the NVIDIA developer forums!

Very weird effect indeed. Did you try different presets for DLSS or change some of the console command parameters as stated in the Quickstart Guide and see if that changes something?

So far I haven’t seen this kind of problem, but I will ask around if someone finds this familiar.

It seems to happen on all presets. I’m going to do some isolated tests outside of my main project with the demo project to see if I can somehow replicate it.

I think I figured it out.

One of my materials has a DitherTemporalAA.
When DLSS is enabled, it enhances that node and makes it more noticeable.

Yep, makes sense. Any form of AA especially temporal can easily be amplified.

Good to hear you could find a root cause!
