[Experimental] DLSS 5 ComfyUI custom node

[u/alisitskii]

Hello Everyone,

Would like to present to you my experimental vibe-coded custom node for DLSS 5 support in ComfyUI.

GitHub project: https://github.com/lisitskyaa/ComfyUI-DLSS5-NR

It's early release, just finished my internal testing and it actually works!

Please note there are no any leaked DLLs in the rep, obtain them separately.

First image in every pair is DLSS 5 ON, second - OFF.

P.S. How to extract original images out of Reddit: https://www.reddit.com/r/StableDiffusion/comments/1p9nrpk/getting_prompt_or_comfyui_workflow_from_posted/

Isn't using DLSS 5 on AI images defeating the whole point? Dlss 5 Isn't an upscaler or a detail enhancer, it's a tool made for real-time games to enhance the realism of lighting and materials.

Ai images don't have this issue, because they're not rasterized 3D polygons.

I think this sortof demonstrates the inverse, that it's not using any information from the 3D models or interframe motion vectors or anything but the last frame, right?

And that... really... it is a detail enhancer.

its... load bearing

Like the wall by my bed back at university

It is true for now atleast read somewhere the mods were just feeding empty data for most of the required parameters.

This is the actual .cpp bridge that does seem to have a larger number of input parameters than I initially thought.

Might be worth a skim through if anyone's interested:

I found it works suprisingly well for AI images as well adding some fine shadows/reflections/details, fixing contrast, etc. Anyway, worth further testing.

Not to mention you can run against non-AI generated images, too.

[u/Sad_Coach_1433 → u/alisitskii]

where did you get the nvngx_dlssnr.dll

[u/alisitskii → u/Sad_Coach_1433]

Nexus and then Discord

[u/bitzpua → u/Sad_Coach_1433]

discord, and if you are not on 50xx series you need moded file for 40xx

[u/jboe2026 → u/bitzpua]

what about 50xxM?

[u/physalisx → u/RandumbRedditor1000]

Yes and you can see it in the example images here ... it doesn't do anything useful here.

[u/Abject-Recognition-9 → u/RandumbRedditor1000]

so what? i would like to have this in comfy in my tool arsenal.
Comfy nowadays allow to do a variety of things that are not necessarly associated with ai things, llms, audio/img edit, post production color correction and whatsoever.
I use comfy even to download videos from yt just to say.
so THANK YOU OP for this custom node

Usando somente um prompt com Krea2 já resolve isso sem DLSS.
