I have direct X 12. Any solution?
What exactly is your issue?
Does the game run at all?
If not, you might need to install DX9 manually, although Steam should have done that when you first installed CoH (you can have that in addition to DX12). You can simply Google that and install it by hand.
If yes,is it simply bad performance?
In that case, try Tiger's suggestion or play around with your settings. If that doesn't help, try updating your GPU drivers. If you still have issues, please give us more Info about your System, as I can't guess a specific cause unless I know what kind of hardware is involved.
