Compatibility Issue Between DLSS and RTX Video SDK - NVSDK_NGX_Parameter_TrueHDR_Available Fails

Hi everyone,

I’ve encountered a compatibility issue between DLSS and the RTX Video SDK. When I call NVSDK_NGX_D3D12_Init in DLSS, it causes NVSDK_NGX_Parameter_TrueHDR_Available to fail. However, if I remove DLSS, the SDK works as expected without any issues.

Here are the key points of the problem:

  1. Using RTX Video SDK from https://developer.nvidia.com/rtx-video-sdk.
  2. Calling NVSDK_NGX_D3D12_Init in DLSS results in NVSDK_NGX_Parameter_TrueHDR_Available failing.
  3. Removing DLSS seems to resolve the issue.

Has anyone else experienced this, or does anyone have suggestions on how to solve this conflict? Any insights would be greatly appreciated!

Thanks!

Hello @samuel74 and welcome to the NVIDIA developer forums.

I asked around internally and this is indeed known as a possible issue. There is no quick or easy workaround available though. It should be fixed with the next update to the RTX Video SDK, but I do not have a release date I could share.

Thanks!
