I ended up here. Sent from NVIDIA Live Chat.
Would be someone so nice to guide me where can I read about getting access to DLSS?
DLSS for Unreal Engine 4. I’ve compiled a branch with DLSS but it requires "NGX Application ID, provided by NVIDIA"
Here is a Membership required. Even when my account is approved for developer program.
On github there is only information “Installation Steps 1. Reach out to your Nvidia contact and get an AppId (also known as a CMSID) for your app. You will need this ID number in order to get DLSS working for your game. Without a CMSID set in the Project Settings of your game, DLSS will not work.”
But even Live Chat couldn’t answer on that. Please help.
