NGX Release 1.0.0

(Latest Release)

This is the first release of NGX.

Key Features and Enhancements

This NGX release includes the following key features and enhancements.

Image Super-Resolution (nvngx_dlisr.dll)
Image Scaling in 2x, 4x or 8x increments. The expected performance of this feature would be measured in seconds per frame, therefore, this version is best suited for still images or offline processing.
Video Super-Resolution (nvngx_dlvsr.dll)
Image Scaling in 2x or 3x increments. The expected performance should be a few milliseconds per frame, therefore, this version is best suited for real-time applications.
InPainting (nvngx_dlinpainting.dll)
Replaces parts of the source image as defined by a monochrome mask. There are two optimization options or models to help guide the inpainting:
  • Mode 0 is best for landscapes
  • Mode 1 is a general broad image type
Slow Motion / Frame Insertion (nvngx_dlslowmo.dll)
Takes a pair of frames and generates new frames between them.


This release has been tested on:

  • Driver: Windows 10 R410 and R415 display drivers
  • GPU: Quadro, GeForce and Titan RTX

Limitations In 1.0.0

  • The sample applications do not perform robust checking for file extensions on image or video types and will crash with missing extensions.
  • The NGX SloMo and NGX VSR sample applications may have issues with certain video types which are not compatible with the FFMPEG version that uses the NVIDIA RTX video decoders. We recommend using one of the formats listed here:
  • This release does not support the DLSS feature. If you are interested in integrating DLSS into your application, contact

Using NGX 1.0.0

Ensure you are familiar with the following notes when using this release.

  • The features do not currently scale their performance across multiple GPUs.
  • Some of the features can use large amounts of GPU memory. Reducing the input image size will reduce the memory usage.

Known Issues

  • When installing the NGX SDK in the default location on a system that has never had an NVIDIA GPU in it, the sample applications may not compile correctly. To work around this issue, either install the SDK into a different location or change the security permissions on %programdata%\NVIDIA Corporation to allow the local user full control.
  • If the NGX SDK is installed on a machine that has CUDA Toolkit version 9.0 already installed, then some of the samples may not compile. In order to compile those samples, the CUDA Toolkit version 9.0 should be uninstalled.
  • The SloMo and VSR samples use the NVIDIA VIDEO Codec SDK to process the videos. Therefore, all videos must be within the resolutions supported by the RTX hardware. For more information, see Key Features of Video Codec SDK.
  • In some cases after a driver update, NGX applications will report that “NGX is Unavailable”. This is normally a pathing issue. Ensure you restart the system and the paths to resolve the issue.
