Blizzard added DirectX 12 support for their award-winning World of Warcraft game on Windows 10 in late 2018. This release received a warm welcome from gamers: thanks to DirectX 12 features such as multi-threading, WoW gamers experienced substantial framerate improvement. After seeing such performance wins for their gamers running DirectX 12 on Windows 10, Blizzard wanted to bring wins to their gamers who remain on Windows 7, where DirectX 12 was not available.
At Microsoft, we make every effort to respond to customer feedback, so when we received this feedback from Blizzard and other developers, we decided to act on it. Microsoft is pleased to announce that we have ported the user mode D3D12 runtime to Windows 7. This unblocks developers who want to take full advantage of the latest improvements in D3D12 while still supporting customers on older operating systems.
Let that sink in: Microsoft backported Direct X 12 to Windows just for World of Warcraft. I guess World of Warcraft is just as important as SimCity.
