UE5 5.6 - DLSS

Gaming and Visualization Technologies DLSS
1

Hello everyone!

I know that an official release of DLSS for UE5 5.6 is ways, ways off, especially seeing how 5.6 is in Preview still.
So this is really only directed at the community, has anyone tried to get it working yet?
The compilation errors in the DLSS uplugin are easy to fix, the rest compiles well, but it seems like the actual upscaling/denoising isn’t working correctly.
The only way to get a semi clean image is when using Preset A, which would be an indicator that there’s issues with getting the motion vectors maybe?

Were you able to compile it for 5.6? I’m getting thousands of errors… Could you please send it to me so I can run some tests? TY… Did you try DLSS 4 preset K?

Hey, like I said, compilation is trivial, I don’t want to share a non working build though.
The transformer model preset won’t help you much either if the temporal history does not work.

Do you folks know where is the github repo of it?

Hi @Alexand3r and welcome to the NVIDIA developer forums.

In general all DLSS information can be found here: NVIDIA DLSS | NVIDIA Developer

The Streamline download link will lead you to github.
But I am not sure which sources the OP has used to compile a UE plugin. That can differ.

Thanks!

Hmm, I can’t edit the original post,
but the full release of 5.6 seemed to require a few more changes, but the compiled result seems similar.
I think it’s actually only the Lumen Indirect pass that does not get denoised on 5.6 with DLSS, whereas it’s fine with TSR. Same goes for Megalights.
The rest/motion vectors etc seem fine.
But again, if someone has some actual insight, please!

Hi Markus, I am looking for the code for the UE plugins for dlss, I know there are download links, but there might be a repo somewhere where people can do a pull request with the fix for UE 5.6

I’m honestly surprised by how long it’s taking to update the plugin. I expected a much quicker turnaround, especially considering how important it is.

usually some intrepid forum member does a little holdover compile - i’d give it another few days.

I’ve managed to compile it. Not sure if it’s working right, but you can run your project at least. (In my project I’m getting crash after exiting PIE on some levels so it defenetly not a solid solution). I also will be happy if someone will provide more stable version.

UPD: Link was updated.

It took them 6 months to release the update for UE5.5. But hey, it’s not like we are talking about multi-trillion-dollar company, gotta give this small indie company some time

Oh, I uploaded wrong version. Give me 30 mins to update link. My bad…

Hey I updated download link. You can try it out.

(arthe0) I’ll give it a try and see how it goes TYYYY. It’s incredible that someone outside of NVIDIA (a company with such limited resources) is trying to update the plugin. Thanks to the community for the effort. But what more can we expect? NVIDIA hasn’t even been able to release a decent driver in recent months

In my project it works — I used your build, and it works perfectly in my project. Thank you so much! (Oh, praise be to arthe0 — long live!)

Welcome @digitalkibble and @arthe0 to the NVIDIA developer forums.

Special thank you to @arthe0 for providing some experimental compilation for others to try.

Thanks!

“Oh no! Packaging failed!” It works perfectly in the editor.. Can Fix packaging? Ty Master.

I don’t think I can fix it (at least I’ll try). Unfortunately, my build is only for testing things in the the editor. We all need to wait for the official release…

Guess this time will be much faster. Don’t forget that with 5.5 the update to DLSS 4 for the RTX50 series was done and it took time for the GPUs to be released and drivers established. All other updates before were DLSS 3 based.
