Games and applications leveraging the DirectX 12 API will no longer work on Intel’s 4th Gen Core iGPUs (Haswell) starting with driver v220.127.116.1107. The following integrated graphics solutions are 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™
The reason behind the block is a potential security vulnerability in the iGPUs of these processors which may allow escalation of privilege. Intel has released a software update to mitigate this potential vulnerability. In order to mitigate the vulnerability, DirectX 12 capabilities were disabled.
If you absolutely need to run DirectX 12 applications on these processors’ integrated graphics solutions for whatever reason, you can downgrade the driver to version 18.104.22.16863 or older.
