NVIDIA GeForce Quadro / Studio Driver 451.77


Recommended Posts

NVIDIA Studio Drivers provide artists, creators and 3D developers the best performance and reliability when working with creative applications. To achieve the highest level of reliability, Studio Drivers undergo extensive testing against multi-app creator workflows and multiple revisions of the top creative applications from Adobe to Autodesk and beyond.


This Studio 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.

In addition, this driver adds support for Vulkan 1.2 as well as optimal support and bug fixes for the latest creative applications from Adobe, Autodesk, Blender, Chaos, and Corel.

Learn more about these new releases in our Studio Driver article here.


Release 450 is an 'Optimal Drivers for Enterprise' (ODE) branch release. ODE branches are designed and tested to provide long-term stability and availability, making drivers from these branches ideal for enterprise customers and other users requiring application and hardware certification.

Quadro ODE drivers are a superset of the NVIDIA Studio Drivers and provide all the benefits of the Studio Driver, in addition to Quadro-specific enhancements and testing.

Fixed Issues in Version 450 U2

  • [Adobe Premiere]: Adjustments in Lumetri color panel causes video to appear noisy.
  • Blue-screen crash occurs pointing to 0x9F Power State Failure error.
  • [Quadro notebook]: Under circumstances where the display driver fails to load properly, a bug check may occur in the driver during the attempt to recover.
  • [Dassault]: Excessive acceleration structure alignment requirements for Vulkan makes Vulkan raytracing unusable in some cases.
  • [PTC Creo]: Clipping occurs when viewing a mold in Draft Check mode under various configurations.
  • [PTC Creo 3]: Performance drop occurs when spinning a Creo model where vertex-specific colors have been applied.
  • [Dassault Systemes][Optix 6]][Quadro RTX]: Accessing a model results in a CUDA error pointing to an illegal memory access.
  • [Adobe Fresco] Flickering texture corruption occurs while interacting with the canvas.

Open Issues in Version 450 U2

  • [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.
