Hi,

Although I found one post in this forum about integrating DLSS in a custom engine which has the same issue ([DLSS SDK "NVSDK\_NGX\_Parameter\_SuperSampling\_Available" returning 0](https://forums.developer.nvidia.com/t/dlss-sdk-nvsdk-ngx-parameter-supersampling-available-returning-0/227646)), the user’s answer doesn’t help, hence my post.

The problem, after initializing NGX and getting the parameter map through GetCapabilityParameters, when I execute Get(…) for NVSDK\_NGX\_Parameter\_SuperSampling\_Available, I get the ‘NVSDK\_NGX\_Result\_FAIL\_FeatureNotSupported’ error. To verify the setup I checked the DLSS\_Sample\_App code that comes with the DLSS 2.4.0 SDK.

The instance extensions (VK\_KHR\_get\_physical\_device\_properties2) and device extensions (VK\_NVX\_binary\_import, VK\_NVX\_image\_view\_handle, VK\_EXT\_buffer\_device\_address and VK\_KHR\_push\_descriptor) are enabled.

Setup info:

- DLSS 2.4.0
- Kernel: Linux 4.14.240 - Ubuntu 18.04.6 LTS
- GLIBC 2.27
- GPU NVIDIA RTX A5000
- GPU Driver Version: 510.47.03
- CUDA Version: 11.6

Hi @MatthieuD, welcome back to the developer forums!

Sorry it took a bit longer to reply.

Are you able to get the sample apps to run on your system at all?

I am trying to find out now if workstation GPUs are maybe not supported by DLSS for some reason. I’ll forward that question internally.

Thanks!
