FAQ

Q: What is the difference between DLSS Super Resolution and DLSS Frame Generation?

A: Super Resolution was introduced with Turing and uses AI to reconstruct images comparable or better than native resolution. Frame generation was introduced with Ada and uses AI to analyze sequential frames and motion data to create additional high quality, responsive frames.


Q: Who is the DLSS Frame Generation SDK for?

A: DLSS Frame Generation executes as a post-process on the GPU, allowing the AI network to boost frame rates even when the game is bottlenecked by the CPU. For CPU-limited games, such as those that are physics-heavy or involve large worlds, DLSS 3 allows GeForce RTX 40 Series graphics cards to render at up to twice the frame rate over what the CPU is able to compute. In Microsoft Flight Simulator for example, with the 1:1 real-world recreation of our planet, DLSS 3 boosts FPS by up to 2X.


Q: What do I get in the DLSS Frame Generation SDK?

A: The SDK includes an integration guide, sample code and a sample application.


Q: What hardware does this work on?

A: DLSS Frame Generation is compatible with Ada generation.


Q: What APIs are supported?

A: DLSS Frame Generation is supported on DirectX 12 and Vulkan (beta).


Q: Can I use DLSS Frame Generation in Unreal Engine or Unity?

A: DLSS FG is compatible with the latest game engines. A plugin is available for Unreal Engine 5.2, simplifying integration. Currently DLSS FG is not available for Unity.

FAQ

Q: My DLSS Plugin is enabled, but I’m not seeing the dropdown menu tool, how do I fix this?

A: There are multiple items that can cause the DLSS dropdown menu tool to not be visible. To ensure your machine and project are both fully supported, please verify that the following guidelines are met.

  1. You have a project using UE 5.0 or prior.
  2. Minimum Driver version of 531.68 is installed on your machine. You can download and install the latest version either directly through GeForce Experience or simply download and install the driver from https://www.nvidia.com/drivers.
  3. Ensure you’re using the corresponding plugin version for the engine you’re running. Please follow the DLSS_Plugin_Installation_Guide.pdf for further instructions on how to install.
  4. The "Enable DLSS to be turned on in Editor viewports" checkbox is marked in your project settings under "Plugins - NVIDIA DLSS".
  5. Your editor viewport is set to Perspective and Lit modes. DLSS Plugin does not support the other viewport modes.
  6. The DLSS Plugin is not compatible with the RenderDoc Plugin. Please be sure to check if you have the RenderDoc Plugin enabled in your project’s Plugins settings. If it is enabled, please disable and restart the engine.

DLSS support can be verified by searching in the UE5 and EU4 log files for “LogDLSS: NVIDIA NGX DLSS supported 1” and related messages. If you still do not see the dropdown menu tool, please email us at DLSS-Support@nvidia.com.


Q: Can anyone use the NVIDIA DLSS Plugin?

A: Yes, the NVIDIA DLSS Plugin is available to all for Unreal Engine 5 and Unreal Engine 4. However, non-plugin versions of DLSS are available through a standalone SDK. NVIDIA DLSS Frame Generation binary compatibility is available for Unreal Engine 5.2. Source code is available for NVIDIA DLSS Frame Generation support in Unreal Engine 4.27, 5.0, and 5.1.


Q: What version of Unreal Engine can the DLSS Plugin be used with?

A: The NVIDIA DLSS Plugin is available for use with Unreal Engine 5 and Unreal Engine 4. Please be sure to pull the corresponding plugin version for the engine you’re running. NVIDIA DLSS Frame Generation binary compatibility is available for Unreal Engine 5.2. Source code is available for NVIDIA DLSS Frame Generation support in Unreal Engine 4.27, 5.0, and 5.1. *Further information can be found in the DLSS Frame Generation Quick Start Guide.pdf in the DLSS 3 Plugin.


Q: Why doesn’t the Cinematic Camera DOF work with DLSS?

A: DLSS workload occurs in the same spot as TAAU in the pipeline. Due to this, DOF differences are expected. Please refer to the Unreal Engine documentation for more details.


Q: How can I use NVIDIA DLSS with other upscaling technologies for cross platform support?

DLSS workload occurs at the same point as other upscaling technologies in the render pipeline. This is an implementation requirement in Unreal Engine. Due to this, only one upscaling technology can be "enabled" (loaded) at a time. This keeps the NVIDIA DLSS plugin enabled but also avoids potential incompatibilities by skipping the driver side NGX parts of DLSS.


Q: I get unexpected results in my PostProcessingmaterials with DLSS

A: DLSS workload occurs in the same spot as TAAU in the pipeline. Due to this, post processing material differences can occur. Please refer to the “View Size and Render Target Size” and “Post Process Material after Temporal Upsample” sections of Unreal Engine documentation for more details.


Q: Is VR Supported?

A: The DLSS Super Resolution Plugin is compatible with VR Supported Unreal Engine Apps.


Q: Is Movie Render Queue (MRQ) Supported?

A: There is no official support for MRQ with the DLSS Plugin. The DLSS Plugin interface only enables DLSS for the main views.


Q: I see ghosting on dynamic geometry. Are there any engine settings related to that?

A: DLSS requires correct motion vectors to function properly. The r.BasePassForceOutputsVelocity console variable can be used to render motion vectors for all objects, and not just the ones with dynamic geometry. This can be useful if it's infeasible to e.g. change all meshes to stationary or dynamic.


Q: Why am I not seeing NVIDIA DLSS Frame Generation working in Play In Editor (viewport and standalone viewport) mode(s)?

A: NVIDIA DLSS Frame Generation offers various support for modes:

  • Selected Viewport (main Editor window)
    • DLSS Frame Generation is not supported
    • Blueprint logic reports FG as supported which is helpful when developing UI + Blueprint, however enabling FG will not actually run it
  • New Editor Windows - Play In Editor (PIE)
    • DLSS Frame Generation is partially supported
    • Possibly with reduced image quality since some of the additional input buffers to DLSS Frame Generation are not available in this PIE mode.
    • Blueprint logic reports Frame Generation as supported which is helpful to develop UI + Blueprints
  • Standalone Game
    • DLSS Frame Generation is supported
    • Same support as a packaged build

Q: If I want to report an issue to NVIDIA, who do I report to and what information should I send?

A: Please report your findings by emailing the NVIDIA DLSS Support Team at DLSS-Support@nvidia.com. When sending your report, please also attach the *.log files from <YourProject>\Saved\Logs so we may better assist you.
