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), 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
