Intel GPU WDDM 3.1 drivers released for Windows 11 22H2, here’s everything new

Written by admin

While Windows 11 22H2 is currently under testing and its commercial release is still weeks away, chipmakers like Intel have decided to update their drivers early. Intel has rolled out an update to its graphics driver with support for Windows 11 version 22H2, which will be launched later this year.

One of the key features of Windows 11 is gaming, and Microsoft is taking the experience to the next level by integrating Games Pass into the Widgets board (added with Windows 11 Build 25174). Thanks to the Intel DCH driver update, games that rely on integrated graphics now run smoother on Windows 11 22H2.

Intel driver version uses the WDDM 3.1 model and includes support for the upcoming Windows 11 22H2 feature update. We don’t know what will change with WDDM 3.1, but one of the supporting documents has confirmed that a new feature called “IOMMU DMA remapping” will be introduced with WDDM 3.1.

In version 21H2, dxgkrnl (DirectX driver) only supported IOMMU isolation via 1:1 physical remapping, meaning logical pages opened by the GPU were translated to the same physical page number. With WDDM 3.1, Microsoft GPU allows access to memory via logical addresses, resulting in better performance.

Intel’s Windows 11 22H2 Drops Support For Older CPUs

Intel confirmed that it is dropping support for 10th generation core processors and older. This means that older processors now have extended/legacy support and only get bug fixes.

If your processor is 10th generation or older, you will get (Legacy). For those running on 11th generation or newer processors, they get

“Intel will move 6th to 10th generation Intel Processor Graphics and related Intel Atom®, Pentium® and Celeron® processor graphics to a legacy software support model,” noted the chipmaker.

In addition to support for version 22H2, this update also contains a number of bug fixes.

For example, Intel has fixed an error message that can appear when you start Call of Duty: Vanguard* (DX12). Fixed another bug that causes apps to crash when launching games such as Watch Dogs: Legion* (DX11) when launching the game.

A bug where certain Intel processors may go to sleep when trying to shut down has been fixed in this release.

Intel is also aware of a number of known issues in this release, including a bug that could cause Ghostwire: Tokyo (DX12) to crash and popular titles such as Counter-Strike: Global Offensive (DX9). An identical bug also affects Destiny 2, Stranger of Paradise and Tom Clancy’s Ghost Recon Breakpoint.

How to download the driver from Intel on Windows

Intel’s updated driver will be rolled out automatically via Windows Update in the coming weeks or months. If you can’t wait, there is another way to get the update. Follow these steps to manually install the driver:

  • Go to Intel’s website and download the Intel Driver and Support Assistant (iDSA) tool.
  • Open the Update Assistant utility from the system tray.
