Which DirectX Version? According to the Steam page ARMA 3 can be run in DirectX 10 and 11. How and where can I switch from 11 to 10? And what are the disasvantages?

I ask because I want to switch back to Linux. But I play ARMA 3 in an unit and want to remain there and keep playing ARMA in a tactical/MilSim manner. 

I can't find ressources about how to setup a workable Wine setup together with Wine/TFAR functionality. WineHQ speaks of Garbage in support for ARMA 3. But this relies on the Alpha state in 2013.  

So I want to use VMWare Player 12 which features hardware gpu acceleration. Won't be as nice as in Windows, but will get the job done. But I am limited to DirectX 9 and 10. Therefore I am asking what I have to expect when switching back to Linux.
