NVIDIA DLSS
DLSS is a suite of AI rendering technologies powered by Tensor Cores on GeForce RTX GPUs for faster frame rates, better image quality, and great responsiveness. DLSS now includes Super Resolution & DLAA (available for all RTX GPUs), Frame Generation (RTX 40 Series GPUs), and Ray Reconstruction (available for all RTX GPUs). To get the full benefits of DLSS, download both DLSS Super Resolution and DLSS Frame Generation SDKs/Plugins.
DLSS Ray Reconstruction
(Coming Soon)
DLSS Ray Reconstruction, which enhances image quality by using AI to generate additional pixels for intensive ray-traced scenes, will be coming soon to DLSS 3.5. Please contact your NVIDIA account manager for early access to Ray Reconstruction, or sign up to be notified when it’s publicly available here: https://developer.nvidia.com/rtx/dlss/notify-me

FAQ
A: DLSS Super Resolution uses AI to reconstruct images comparable or better than native resolution. DLSS Frame generation was introduced with Ada (RTX 40 Series GPUs) and uses AI to analyze sequential frames and motion data to create additional high quality, responsive frames. DLSS Ray Reconstruction replaces hand-tuned denoisers with an NVIDIA Supercomputer-trained AI network that generates higher quality pixels in between sampled rays.
A: The SDK includes an integration guide, sample code and a sample application.
A: Any GeForce RTX GPU can support DLSS Ray Reconstruction and DLSS Super Resolution as they feature the required Tensor Cores. DLSS Frame Generation requires a RTX 40 Series GPU.
A: DLSS Ray Reconstruction is supported on DX12 and Vulkan (beta).

FAQ
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.
- You have a project using UE 5.0 or prior.
- 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.
- Ensure you’re using the corresponding plugin version for the engine you’re running. Please follow the Getting Started with DLSS guide for further instructions on how to install.
- The "Enable DLSS to be turned on in Editor viewports" checkbox is marked in your project settings under "Plugins - NVIDIA DLSS".
- Your editor viewport is set to Perspective and Lit modes. DLSS Plugin does not support the other viewport modes.
- 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.
A: Yes! NVIDIA DLSS 3.7 binary compatibility is available for Unreal Engine 5.2 and later. Source code is available for Unreal Engine 4.27, 5.0, and 5.1.
A: Please contact your NVIDIA account manager for early access to Ray Reconstruction, or sign up to be notified when it’s publicly available here: https://developer.nvidia.com/rtx/dlss/notify-me.
A: Source code to the DLSS SDK is at https://github.com/NVIDIA/DLSS
A: DLSS workload occurs in the same spot as TAAU in the pipeline. Due to this, DOF does not play well with upscalers. Epic has provided additional information regarding this here.
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.
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.
A: The DLSS Super Resolution Plugin is not compatible with VR Supported Unreal Engine Apps at this time.
A: Yes, it’s supported
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.
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
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.
