DirectX 9, 10 or 11??

This question is aimed at those of you that have installs of both FS9 and FSX.

I've been reading about the newest versions of DirectX, and am a little confused as to the newer versions.

If and when I get a new system (running Windows 8), should I stay with FS9 or install one of the newer versions? OR, can you have multiple versions of DirectX installed, say Version 9 for FS9 and Version 11 for FSX?

Can some of you guys share your experience and advice. Thanks in advance.

Cheers and Happy New Year.

As far as I know, the higher versions are backward compatible. Every sofware title I've seen that required DX listed the requirement with "or higher" at the end.
 
I installed Rise of Flight awhile back. Even though it flashed it all in my face, I didn't realize I was watching it install DX11. Everything ran as normal, FS9, FSX, the works.

I had no idea until I was reinstalling, retweaking FSX, and checked my version of DX, thinking about upgrading to DX10.....that I found it was already updated beyond.

...."Duh...."

FSX seems to be running a bit better...maybe. Could be a placebo effect.

DirectX can do that.

To me.
 
As I remember it, FSX is coded to take advantage of DX10. If so, a few extra frames would not be out of place with the jump from 9 to 11.
 
DirectX versions can't be picked at will.

If you run the installer on Windows XP, it will only install all DirectX modules up to version 9; if you run it on Windows 7, it will install all versions up to DX11.1; DirectX 12 is Windows 8 exclusive.

Choosing what version of DX will be used is up to the application. Some leave you the choice (like FSX), others simply use what thy were coded for.
