DirectX 12 applications are no longer meant to run on the integrated graphics of Intel’s 4th Gen Core “Haswell” processors. This is owed to a new security vulnerability, which prompted Intel to release a new driver (15.40.44.5107) that deprecates the DirectX 12 capabilities of various Iris and HD Graphics controllers. Haswell users who wish to run DirectX 12 applications on their iGPUs will need to downgrade to the 15.40.42.5063 (or older) driver.

From Intel:

A potential security vulnerability in Intel Graphics may allow escalation of privilege on 4th Generation Intel Core processors. Intel has released a software update to mitigate this potential vulnerability. In order to mitigate the vulnerability, DirectX 12 capabilities were deprecated.

Intel Graphics Controllers affected:

  • 4th Generation Intel Core Processors with Intel Iris Pro Graphics 5200
  • 4th Generation Intel Core Processors with Intel Iris Graphics 5100
  • 4th Generation Intel Core Processors with Intel HD Graphics 5000/4600/4400/4200
  • Intel Pentium and Celeron Processors with Intel HD Graphics based on 4th Generation Intel Core

Intel debuted its Haswell microarchitecture in 2013. The processors (e.g., Core i7-4790K) were built on a 22-nanometer process.

  1. I don’t think integrated GPU’s on CPU’s of that era can do much in the way of DX12 gaming in the first place.
