Looking for the latest DLSS for UE 4.27 - need help!

Hello everyone,

I’m currently working on a project in Unreal Engine 4.27 and need to integrate NVIDIA’s DLSS plugin to boost performance. Unfortunately, the official NVIDIA website no longer provides download links for the DLSS plugin compatible with UE4.27 - only the newer DLSS 4 for Unreal Engine 5 is available.

I’d prefer not to migrate my project to UE5, as it would take too much time and effort. So, I’m reaching out to ask if anyone knows where I can find the latest version of the DLSS plugin for UE4.27 or has a copy they could share. I’ve searched forums and other sources but haven’t found it yet.

Any help or pointers to a reliable download source would be greatly appreciated. Thanks in advance!

P.S. I know there is a DLSS 3.5 archive online, but I know that the last DLSS 3.7(which is the latest and most available) version available was for Unreal Engine 4. Please help me to find it exactly

Hi @gabelogan0109, welcome to the NVIDIA developer forums.

You could have left your original post in the Unreal category as well, close enough to the topic :-)

The team is working on a web page specifically for deprecated plugin packages for older UE versions. So stay tuned.

Since older versions will not get maintained any longer, they will be provided “as is”.

Thanks!

Thank you very much. I’ve already built the latest available DLSS 3.7 version for Unreal Engine 4.27 myself, using the source code on the Unreal Engine github

Who needs the plugin now, here is a link to it. Also attached a screenshot with the result of scanning the archive.
