Surprisingly no one pointed this out yet, but this is 110% because of China. WOW is big in China and it is probably the biggest Windows 7 market, you could see that by looking at Steam statistics when Chinese PUBG players flooded Steam and Windows 7 usage increased significantly. Also the Warcraft movie made more than half of its revenue in China alone. It grossed 215$ million in China and less than 50$ million in USA. So, I am expecting that the other games that get DirectX 12 support on Windows 7 will also be games that are popular in China.
