WinEQ on Windows 10 and DX11
DirectX 9 is completely different from 10 and 11 which are also drastically different from 12. WinEQ 2 supports DirectX 8 and 9. It will never support 10, 11, or 12, and that probably will never matter -- EverQuest uses only DirectX 9, so as far as playing EverQuest, the fact that you have DirectX 10, 11 and 12 doesn't really matter.
