That's not true. Your OS and your video card can run DX9 without problem. You don't need to "downgrade" anything. DX9 and DX11 can both run on the same computer and same video card. Installing DX9 will not downgrade your DX11.
Fortunately that's not how it works and will never work, its always backwards compatible (problems with very old games due to newer OS are different story), DX11 machine can run DX10,9,8,7... as well
Some older and mobile graphics cards have had issues with DirectX 9 compatibility. But that was resolved years ago with the new drivers. Most cards in the market now supports DirectX 11 but they all can run previos versions. If your board can't enter in DirectX 9 mode, you will not be able to see the rFactor2 menu.
I can see the menu and press the button rFactor2 RACE. If anyone knows how I can do to put the DX9 it please guide me because I do not know how. I can perfectly play the BattleField 3 but I can not play the most anticipated game for me. If I could I would do the necessary, but I do not know what to do. Help me. Remembering that I can play Kart Racing Pro without problems.
