Intel disables DirectX 12 support on older processors in the latest update. The cause of the security vulnerability

Only a few days ago, the 12th generation of Intel processors, the Alder Lake-S family, appeared on the market. However, in use in many people’s home computers, there are still older units that perfectly fulfill the sentences placed before them, despite the use of inferior lithography. For example, the Haswell microarchitecture first appeared on the market in mid-2013, that is, more than 8 years ago. It was based on a production process at 22 nm, where 10 nm is currently used. However, Intel Core i5 and quad-core i7 are still successfully used for content consumption. Unfortunately, we do not have good news for the owners of these processors. Intel has decided to disable their DirectX 12 feature set.

The latest graphics driver update disables DirectX 12 support on Intel Haswell processors. This is the “fix” of the vulnerability.

Intel Corporation inform On disabling DirectX 12 API support on 4th generation processors, the Haswell family, which first appeared on the market in 2013. This applies to Core, Pentium and Celeron units with integrated graphics such as Intel Iris Pro Graphics 5200 and 5100 and Intel HD Graphics 5000 and 4600, 4400 and 4200. The reason is that there is a bug inside the console, and disabling DirectX 12 should “fix” that. This is the easiest and fastest solution for Blue, but unfortunately the most harmful to consumers.

It is true that the old iGPUs are not the most efficient and certainly not suitable for the latest AAA games, but they have succeeded in dealing with many emulators and software, an example is the famous Dolphin which supports Nintendo consoles such as the GameCube and Wii. What to do if you are not afraid of the vulnerability and do not want to lose DirectX 12 support? Use the integrated graphics driver version 15.40.42.5063 or earlier. Update 15.40.44.5 only107 This brings up the Security Patch.
