Hi, I recently unchecked the DX-10 preview box in FSX (back to dx-9) so I could use Enbseries again. Soon after I realized that I really really wanted DX-10 back. I was about to check the DX-10 preview box again when I noticed there was no box for it anymore.

 

I am wondering if there is any way to get DX-10 back in FSX after the box is unchecked?

Try adding the line - "D3D10=1" in your [GRAPHICS] section in the FSX.cfg

There is already that line in my FSX.cfg and it does not seem to be activating DX-10.

Maybe a re-install is in order? But I'd wait for a couple days to see if someones else has any other alternative solution...
