Deep learning super sampling (DLSS)

NVIDIA Deep Learning Super Sampling (DLSS) is a rendering technology that uses artificial intelligence to increase graphics performance. The High Definition Render Pipeline (HDRP) natively supports DLSS. For more information about DLSS see Deep learning super sampling.

Requirements and compatibility

This section includes HDRP-specific requirements and compatibility information for DLSS. For information about the general requirements and compatibility of DLSS, see Deep learning super sampling.

Platforms

HDRP supports DLSS on the following platforms:

DirectX 11 on Windows 64 bit DirectX 12 on Windows 64 bit Vulkan on Windows 64 bit HDRP does not support DLSS for Metal, Linux, Windows using x86 architecture (Win32), or any other platform.

To build your project for Windows, use x86_64 architecture (Win64).

For information about the hardware requirements of DLSS, see NVIDIA'S DLSS requirements.

Using DLSS

To use DLSS in your scene, you must:

  1. Add the NVIDIA package.
  2. Enable DLSS in your HDRP Asset.
  3. Enable DLSS for each Camera you want to use it with.
  4. Set the DLSS quality mode.

Adding the NVIDIA package

To add the NVIDIA package to your Unity project, there are two methods you can use. To install it automatically:

  1. Select an HDRP Asset and view it in the Inspector.
  2. Go to Rendering > Dynamic Resolution and click Install NVIDIA Package.

To install it manually:

  1. Open the Package Manager window (menu: Window > Package Manager).
  2. Select Packages, then select Built-in.
  3. In the packages list view, find and select the NVIDIA package.
  4. In the bottom right of the package-specific detail view, select Enable.

Enabling DLSS

After you install the NVIDIA package, more properties appear in HDRP Assets and Cameras. This allows you to enable DLSS in your HDRP project. To do this:

  1. Select the HDRP Asset you want to enable DLSS for and view it in the Inspector.
  2. Go to Rendering > Dynamic Resolution and select Enable.
  3. In the dynamic resolution section, select the Enable DLSS property.

Your Unity project now supports DLSS and you can now enable DLSS for Cameras in your scene. Enabling DLSS in the HDRP Asset exposes other properties that you can use to customize DLSS. For information about these properties, see the HDRP Asset documentation.

  1. In the Hierarchy or Scene view, select a Camera and view it in the Inspector.
  2. Select Allow Dynamic Resolution to expose the DLSS settings. For more information see the Dynamic Resolution guide.
  3. Select Allow DLSS.
  4. Enable Allow DLSS to expose other properties that you can use to customize DLSS for the Camera. For information about these properties, see the Camera documentation.

DLSS and Dynamic Resolution

The Use Optimal Settings checkbox in the HDRP Assets is enabled by default. This means that DLSS sets the dynamic resolution scale automatically. If you disable this checkbox DLSS uses the same dynamic resolution scale set by the project. For more information see the Dynamic Resolution guide.

Setting the DLSS quality mode

DLSS now works in your project, but you can change the quality mode to customize DLSS towards performance or quality. You can do this on a project level or a per-Camera level. For information about the available quality modes, see Quality modes.

To change the DLSS quality mode for your whole project:

  1. Select the HDRP Asset that has DLSS enabled and view it in the Inspector.
  2. Go to Rendering > Dynamic Resolution > DLSS and set the Mode property to the quality mode you want.

To override the DLSS quality mode for a particular Camera:

  1. In the Hierarchy or Scene view, select a Camera and view it in the Inspector.
  2. Select Use Custom Quality.
  3. Set the Mode property to the quality mode you want.
