Additional information
Release 455 is a Quadro New Feature (QNF) driver. QNF drivers provide users the flexibility to try new features made available outside the launch cycle of longer-lived Optimal Driver for Enterprise (ODE) branches. QNF drivers are tested for workstation environments and are recommended only for those users who need specific features mentioned in the release highlights or release notes.

Quadro Release 455 comprises the entire suite of Quadro features, as well as all NVIDIA Studio Driver features.

For the most stable and fully supported enterprise driver please use the ODE graphics drivers downloadable from the main NVIDIA driver download page.

New in Release R455 U1

New Studio Features

  • NVIDIA Deep Learning Super Sampling (DLSS) support added for D5 Render and SheenCity Mars.

    • DLSS is an AI super resolution algorithm that utilizes RTX Tensor Cores to boost frame rates, increasing viewport interactivity while maintaining visual fidelity.

  • Support for NVIDIA Broadcast application, which uses the dedicated Tensor cores in Quadro RTX GPUs to offer:
    • Noise Removal: removes background noise from microphone feed.
    • Virtual Background: removes the background from webcam feed and replace it with an alternative image, Windows app, a game, or subtle blur.
    • Auto Frame: zooms in on the user and applies AI to track head movements, maintaining centered frame.

CUDA 11.1 Support

  • Added new PTX Compiler static library that allows compilation of PTX programs using supplied APIs.
  • Added the 7.1 version of the Parallel thread Execution instruction set architecture (ISA).
  • Unified programming model for:
    • async-copy
    • async-pipeline
    • async-barrier (cuda::barrier)
  • Added hardware accelerated sparse texture support.
  • Added support for read-only mapping for cudaHostRegister.
  • Multi-threaded launch to different CUDA streams is supported.
  • CUDA Graphs enhancements:
    • improved graphExec update
    • external dependencies
    • extended memcopy APIs
    • presubmit
  • Introduced new system level interface using /dev based capabilities for cgroups style isolation with Multi-instance GPU (MIG).
  • Improved MPS error handling when using multi-GPUs.
  • Users can now configure and query the per-context time slice duration for a GPU via nvidia-smi.
  • Improved detection and reporting of unsupported configurations.

Fixed Issues in Release R455 U1

  • [PTC Creo]: Improved the application wireframe performance.

Open Issues in Release R455 U1

  • [Alchemist]: The application crashes when either changing the display resolution or switching to another display with a different resolution.

    • To workaround, avoid changing the resolution, or disconnecting from or connecting to an external display with the application opened.
