I understand you would like to know if Intel® Iris™ Graphics 540 supports or not WDDM 2.2.
Let me apologize for any inconvenience this issue may be causing to you.
Currently we only offer WDDM 2.2 support for Kaby Lake graphics controllers.
Right now there are no details as to whether we will offer WDDM 2.2 for Intel® Iris™ Graphics 540 in the future.
