Intel has just released version 30.0.101.1191 of the DHC driver update, which claims to bring an improved Windows 11/10 performance experience to users with 6th generation processors and above.
Issues fixed by this update
As for bug fixes, this update mainly addresses issues with the Desktop Window Manager (DWM.exe). It is critical to the GUI of the Windows operating system and covers support for taskbar thumbnails, application windows, animations, high resolution screens, and other visual effects.
Under normal circumstances, the Desktop Window Manager should run smoothly in the background and not be an abnormal drain on system resources - for example, around 2-8% of the processor consumes less than 100MB of memory overhead.
However, part of the installation of Intel drivers or the system itself in the case of bugs, may cause DWM.exe occupy too much system resources, and even trigger Windows 10/11 operating system instability.
Thankfully, while Microsoft is still introducing several fixes for Windows 11 performance issues, Intel has been the first to release a new version of the driver to fix critical stability issues using its own core graphics devices.
Intel wrote in the changelog that the update focuses on improving the stability of Intel's 6th to 10th generation Core processors with Windows Desktop Window Manager.
Improvements brought by this update
In addition, as part of the December 2021 update, the new graphics driver also brings the following improvements:
- Improved performance for games such as Halo: Combat Anniversary Edition when playing in Classic Graphics mode.
- Fixes an issue that could cause frequent crashes or lags when playing games such as Battlefield 2042 or FIFA 21.
- Fixes for graphical anomalies in Shadow of the Tomb Raider: Shadow / Rise of the Tomb Raider games.
Finally, even if you don't download the update manually, the Windows Update channel usually pushes out new versions of drivers within a few weeks to a few months (depending in part on how much attention the OEMs give them).
For those who need it, you can go to the Intel website, or get the DHC driver update version 30.0.101.1191 through the Driver Support Assistant (iDSA) tool.
