Direct X 12 switch to ll

@87458752  You don't need to change anything about DirectX.  As I mentioned, Sims 4 uses DirectX 9, which will be installed when you install the game itself.  You can have multiple versions of DirectX installed at the same time, and a given application will be able to call the version it needs.

By the way, when people talk about switching to, say, DX11 for a given game, they don't mean switching their systems, they mean telling the game to use a different DX version.  It's quite difficult to uninstall a DX runtime, and current versions of Windows 10 come with DX12 anyway.
