content: On games, most do not require DX12. If it does, do not buy it. DX11 covers a lot. Many games are still DX9. I look forward to Vulcan kicking DX12's ass into irrelevance. There is no legitimately good reason to use Win 10. It will always steal CPU cycles to run its keylogging stuff that it sends to Microsoft (and by extension anyone Microsoft will send it to).
