DLSS-RR (sl.dlss_d) not supported on RTX 4050 Laptop GPU with Streamline SDK 2.11.1

Hi,

I’m integrating DLSS-RR into a custom D3D12 engine using Streamline SDK 2.11.1, but the sl.dlss_d plugin is being ignored on my system.

Environment:

  • GPU: NVIDIA GeForce RTX 4050 Laptop GPU (AD107)
  • Driver: 610.62
  • Streamline SDK: 2.11.1
  • OS: Windows 11 (10.0.26200)
  • API: D3D12

Symptoms:

  • sl.dlss_d is loaded but immediately ignored with the message: Ignoring plugin 'sl.dlss_d' since it is not supported on this platform
  • getNGXFeatureRequirements returns ngxResult failed 0xbad00005 for both DLSS and DLSS-RR
  • slIsFeatureSupported(kFeatureDLSS_RR, ...) returns eErrorFeatureNotSupported
  • nvngx_dlssd.dll is not present in the DriverStore (nvmii.inf_amd64_62de3bd48abb42a6)
  • nvngx_dlss.dll (v3.10.x) is placed in the executable directory

What I have tried:

  • Updating the driver to 610.62
  • Placing nvngx_dlssd.dll (v3.10.x) in the executable directory and in C:\Windows\System32\
  • Setting projectId in sl::Preferences
  • Explicitly specifying plugin path via pathsToPlugins

Question:
Is DLSS-RR supported on RTX 4050 Laptop GPU (AD107) via Streamline SDK? If so, what is required to make it work? Is nvngx_dlssd.dll supposed to be included in the driver package for this GPU?

Any guidance would be appreciated. Thank you.
