NVIDIA driver version 451.48 release notes

NVIDIA adds support for DirectX 12 Ultimate.

Earlier today NVIDIA released a game ready driver update (version 451.48) that includes a number of fixes for games such as Sea of Thieves, Just Cause 2, Resident evil 2 Remake, Far Cry 5 and more you can find below. They also added some new features, most notably DirectX12 Ultimate.

This edition of the Release Notes for Windows includes information about NVIDIA graphics driver version 451.48 WHQL and lists changes made to the driver since driver version 446.14.

What’s New in Version 451.48 WHQL

Game Ready Driver Updates

Game Ready Drivers provide the best possible gaming experience for all major new releases. Prior to a new title launching, our driver team is working up until the last minute to ensure every performance tweak and bug fix is included for the best gameplay on day-1.

Game Ready for DirectX 12 Ultimate

The new Game Ready Driver provides full support for the new DirectX 12 Ultimate graphics API. This includes support for DirectX Raytracing (DXR) version 1.1 as well as support for mesh shaders, sampler feedback, and variable-rate shading (VRS). Additionally, this driver supports Hardware-accelerated GPU Scheduling when used with the Windows 10 May 2020 Update.

New Features and Other Changes

  • Supports DirectX 12 Ultimate
  • Supports Vulkan 1.2
  • Supports hardware-accelerated GPU Scheduling.
  • Supports CUDA 11.0.

Application Profiles

  • DCL – The Game (NVIDIA Turing GPUs and later)
  • Jiu Xiao
  • Monster Energy Supercross 2 – The Official Videogame (NVIDIA Turing GPUs and later)
  • MORDHAU (NVIDIA Turing GPUs and later
  • Overpass (NVIDIA Turing GPUs and later)
  • Planetside 2 (DirectX 11)
  • Sniper Elite V2 Remastered
  • Spyro Reignited Trilogy (NVIDIA Turing GPUs and later)
  • Surviving The Aftermath
  • System Shock (NVIDIA Turing GPUs and later)
  • The Fisherman – Fishing Planet (NVIDIA Turing GPUs and later
  • Warhammer Underworlds: Online
  • Wolcen: Lords of Mayhem

Experimental OpenCL 2.0 Features

Device side enqueue:

  • The current implementation is limited to 64-bit platforms only.
  • OpenCL 2.0 allows kernels to be enqueued with global_work_size larger than the compute capability of the NVIDIA GPU. The current implementation supports only combinations of global_work_size and local_work_size that are within the compute capability of the NVIDIA GPU. The maximum supported CUDA grid and block size of NVIDIA GPUs is available at http://docs.nvidia.com/cuda/cuda-c-programming-guide/index.html#compute-capabilities. For a given grid dimension, the global_work_size can be determined by CUDA grid size x CUDA block size.
  • For executing kernels (whether from the host or the device), OpenCL 2.0 supports non-uniform ND-ranges where global_work_size does not need to be divisible by the local_work_size. This capability is not yet supported in the NVIDIA driver, and therefore not supported for device side kernel enqueues.

Shared virtual memory:

  • The current implementation of shared virtual memory is limited to 64-bit platforms only.

Changes and Fixed Issues in Version 451.48

The following sections list the important changes and the most common issues resolved in this version. This list is only a subset of the total number of changes made in this driver version. The NVIDIA bug number is provided for reference.

Fixed Issues in this Release

  • [Just Cause 2]: The game does not detect CUDA files which results in missing “GPU Water Simulation” and “Bokeh Filter” settings. [2994570]
  • [Sea of Thieves]: Issues with game rendering occur. [200614095]
  • [Resident Evil 2 Remake]: The game may display random object and menu flickering. [2997880]
  • [Devil May Cry 5]: The game may display random object flickering. [2997814]
  • [Divinity Original Sin 2 – Definitive Edition]: The game experiences low performance when hardware accelerated GPU scheduling is enabled. [3009631]
  • [Notebook]: Windows Mixed Reality headsets may display jitter when connected to the HDMI port linked to the NVIDIA Optimus notebook integrated graphics. [2971312]
  • [G-SYNC]: G-SYNC does not work with DirectX 9 games if “Disable full screen optimizations” is selected. [2969897]
  • Display brightness increases while enabling GPU scaling. [200612966]
  • NVIDIA HD Audio may disappear after display goes to sleep. [2807732]
  • The cursor turns into a grey rectangle when playing YouTube 4K HDR videos. [3009602]

Open Issues in Version 451.48 WHQL

As with every released driver, version 451.48 WHQL of the Release 450 driver has open issues and enhancement requests associated with it. This section includes lists of issues that are either not fixed or not implemented in this version. Some problems listed may not have been thoroughly investigated and, in fact, may not be NVIDIA issues. Others may have workaround solutions.

Windows 7 Issues

  • [Notebook][H-Clone]: With the integrated graphics processor as the clone source, display settings cannot be changed from the NVIDIA Control Panel. [200594188]

Windows 10 Issues

  • [Sunset Overdrive]: The game may display random green corruption if Depth of Field is enabled from in-game settings. [2750770]
  • [VR}: HDCP errors occur with Valve Index VR. [2967616]
  • [Call of Duty: Modern Warfare]: Color banding can occur in the game after enabling Image Sharpening from the NVIDIA Control Panel. [2889337/3028436]
  • [Call of Duty – Warzone]: Freestyle does not work. (200593020)
  • [Forza Motorsport 7]: The curb may display a black strip during a race on certain tracks. [2781776]
  • [Zombie Army: Dead War 4][Ansel/Freestyle]: The Ansel & Freestyle tabs are unselectable. [2810884]
  • [Tom Clancy’s Rainbow Six Siege][Vulkan][G-SYNC]: When playing the game in Vulkan mode with G-SYNC enabled, flickering occurs after switching the game between full-screen and windowed mode.[200578641]…To work around, either disable G-SYNC or play using an API other than Vulkan.
  • [SLI][G-SYNC]: With multi-GPU and G-SYNC enabled, TDRs occur soon after launching an application. [200628981]
  • [Notebook][The Witcher 3 WILD HUNT]: The game remains minimized when DDS switch is set to Optimus and Automatic, and cannot be restored to full screen. [200628973]
  • [Notebook][H-Clone]: With the integrated graphics processor as the clone source, display settings cannot be changed from the NVIDIA Control Panel. [200594188]
  • [Notebook]: Some Pascal-based notebooks w/ high refresh rate displays may randomly drop to 60Hz during gameplay. [3009452]
  • [Notebook][G-SYNC]: Graphical corruption occurs when windowed G-SYNC+V-Sync is On while running applications in Clone/Duplicate mode. [200628911]
  • [Notebook]: LVDS-display goes blank upon rebooting the system after driver installation on some systems. [200627952]

Issues Not Caused by NVIDIA Drivers

Operating System Issues

  • [Windows 10 Fall Creators Update][HDTV]: 12 bpc is automatically applied even on HDTVs that support only 8 bpc, resulting in a scrambled display. [2007663]To work around, open the NVIDIA Control Panel->Change Resolution page, select “Use NVIDIA color settings”, then set the Output color depth to 8 bpc.
  • When upgrading from Windows 7 to Windows 8, the system fails to retrieve the installed WHQL display driver. [1024416]
