All these years of flying MSFS 2000, 2004 and FSX, and I've never had to familiarize myself with different versions of DirectX. I have always used DirectX 9 with no problems.
But in the past week, I've come face to face with options - DirectX 9, 10, 11 and 12 to choose among.
I am running Windows 10 Insider Preview, and as of the latest update 101240, DirectX 12 is "baked in", and my previous installation of FSX refused to display anything but a black screen.
I uninstalled FSX and installed FSX:SE in desperation, thinking that Dovetail Games would have updated the game to run with Windows 10. But no difference - it can't use DX 12, either.
I "solved" the problem by selecting "Preview DirectX 10" in the Settings page. But is that the only, or best solution?
I have also found that even with DX 10 unselected, and with a forced installation of DirectX 9.0c (June 2010), I can get FSX:SE to display by TOGGLING to Windowed Mode and then BACK to Full-Screen Mode.
Finally, I have heard about Steve Parson's "DX10 Scenery Fixer". I haven't investigated further - I am quite confused about the different ways to run FSX:SE.
Could someone please explain (or point me to some remedial reading) about the advantages and disadvantages of the different versions of DirectX?
