Hello, I’m getting this error:

LogDLSSNGX: [SDK]: [2025-03-31 09:10:02] [NGXLoadLibrary:287] error: failed to load NGXCore: 126 (D:\UE_5.3\Engine\Binaries\Win64_nvngx.dll)

LogStreamlineRHI: SLisFeatureSupported(kFeatureDLSS_G) → (31, Result::eErrorFeatureMissing)

Another person had this issue, but no one seems to know the answer.

Bump. I’m getting the same error on UE5.5 DLSS 4.0.2

Have latest drivers, get this on multiple UE 5.5 engine versions and projects. DX12 is enabled.

Bump. I’m getting it after upgrading my project from UE 5.5 to 5.6 and switching out the DLSS files for the 5.6 versions. Also have the latest drivers
