Windows Virtual Machine Beta Support for GeForce Even though Resizable BAR was one of the most expected features for the new RTX generation and gamers, virtualization on GeForce GPUs was the most expected addition for “HomeLabers” and Linux users. This is the technology we are focusing on in this article. SR-IOV for GPU sharing) on all GeForce graphics cards based on Kepler architecture and newer for Windows virtual machines. NVIDIA OpenCL 3.0 continues to support existing OpenCL 1.2 functionality and Khronos and vendor extensions that are already supported with NVIDIA OpenCL 1.2 drivers.īeta Support for virtualization on GeForce GPUs.Īlso, starting with this driver, NVIDIA has enabled GPU passthrough (not vGPU, a.k.a. Smart Access Memory, SAM (AMD’s term for the technology) was announced last year by the company and has already been implemented.Īdded support for OpenCL 3.0, the latest major version of OpenCL maintaining backward compatibility with OpenCL 1.2. Resizable BAR allows the CPU to access all of a PCIe device’s memory at once, rather than the previous limitation of 256MB per cycle. Here, three import features have been announced: Resizable BAR the GeForce RTX 30 Series, support for OpenCL 3.0, and beta support for virtualization on GeForce GPUs.
However, something particularly exciting about this new release is found under Gaming Technology. This driver supports brand-new video games and offers a fix to open issues presented in many other games and apps. On March 30 of this year, NVIDIA released a new Game Ready Driver, 465.89. Using a software hack has been possible for a long time to enabled GPU passthrough on the consumer GeForce cards and vGPU capabilities. Technically speaking, the technology always has been available in the silicon chip for GeForce, but it was not enabled in the drivers, causing the popular “error 43” on Windows virtual machines. GPU passthrough has been used for a long time, and there were ways to enable it on GeForce graphics cards however, it was never officially supported. For Linux users, this technology will allow playing Windows-only games in your VM or, if you’re a developer, you can more easily test both Windows and Linux code from a single machine, accelerating development.
Prior to driver 465.89, only Quadro NVIDIA cards supported GPU passthrough.
With the latest Game Ready Driver, NVIDIA has enabled GPU Passthrough beta support for Windows virtual machines on GeForce GPUs.
