Tom's Hardwarespotted the update, which
states that DirectX 12 support will end for the affected CPU/GPU
combos starting with Intel graphics driver version 126.96.36.19907.
The affected processor lines and their integrated graphics pairings
debuted in 2013, generally coming off the market the following
year, though desktops and laptops with those CPUs may have been
sold for several more.
For a sense of perspective, most of these
machines would have been sold running Windows 8, like the Lenovo
The full list follows:
4th Generation Intel® Core™ Processors with Intel® Iris™ Pro
4th Generation Intel® Core™ Processors with Intel® Iris™
4th Generation Intel® Core™ Processors with Intel® HD Graphics
Intel® Pentium® and Celeron® Processors with Intel® HD Graphics
based on 4th Generation Intel® Core™
Users who upgrade their graphics card driver, or have it
automatically updated through Windows, will lose the ability to use
DirectX 12. Games and other programs that rely on it will no longer
run, but those with compatibility modes that can work with DirectX
11 or lower should be fine (with slightly less fidelity).
Intel does not say it's working on a fix for the problem:
If users need DirectX 12 support on this particular hardware, they'll have to stay on an older version of the graphics driver. A lack of
resources to dedicate to older hardware (or, for the cynical, a
gentle nudge to upgrade to a newer machine) might be to blame.
The actual impact of this change should be minimal. Even among
those who are running 8-year-old CPUs in their machines, most of
those who care about the extra visual fidelity offered by DirectX
12 over version 11 should have a discrete graphics card, making the
integrated graphics and its driver redundant.
