Downloading The DLSS SDK

The DLSS SDK cannot be redistributed by this crate. You will need to download the SDK as follows:

• Ensure you comply with the DLSS SDK license located at https://github.com/NVIDIA/DLSS/blob/v310.3.0/LICENSE.txt
• Clone the NVIDIA DLSS Super Resolution SDK v310.3.0 from https://github.com/NVIDIA/DLSS/tree/v310.3.0
• Set the environment variable DLSS_SDK = /path/to/DLSS

Build Dependencies

• Install the DLSS SDK
• Install the Vulkan SDK https://vulkan.lunarg.com/sdk/home and set the VULKAN_SDK environment variable
• Install clang https://rust-lang.github.io/rust-bindgen/requirements.html#clang

Distributing Your App

Once your app is compiled, you do not need to distribute the entire DLSS SDK, or set the DLSS_SDK environment variable. You only need to distribute the DLSS DLL and license text as follows:

• On Windows, copy $DLSS_SDK/lib/Windows_x86_64/rel/nvngx_dlss.dll to the same directory as your app
• On Linux, copy $DLSS_SDK/lib/Linux_x86_64/rel/libnvidia-ngx-dlss.so.310.3.0 to the same directory as your app
• Include the full copyright and license blurb texts from section 9.5 of $DLSS_SDK/doc/DLSS_Programming_Guide_Release.pdf with your app

Debug Overlay

When dlss_wgpu is compiled with the debug_overlay cargo feature, and the DLSS_SDK environment variable is set, the development version of the DLSS DLL will be linked.

The development version of the DLSS SDK comes with an in-app overlay to help debug usage of DLSS. See section 8.2 of $DLSS_SDK/doc/DLSS_Programming_Guide_Release.pdf for details.
