[Wine] how to use directx10/11?

[tparker]

Can anyone tell me or point me to information telling me what is the 
correct way to use directx 10 or 11 for games in Wine, what do I need to 
install to do so, and do I then need to use a special tag (like the 
-opengl tag) when starting a game?

I have been googling and having a hard time making sense of the 
information I have been finding. Some places reference a 'wine dx10' and 
some game forum posts say to install directx 10 or 11 (depending on the 
game/video card) via winetricks. I am leery of trying random changes to 
my Wine installation when I haven't been able to find instructions on 
the Wine site for this to verify the steps.
