Ok so I exited p3d V2 after its first use. Later when I rentered the sim it was running but I was just seeing black. The only fix I found was to delete the cfg and let p3d build a new one. I tried again changing settings and got the same result on the start ups past the first with the new cfgs. So I started trying every graphics setting building one on top of the other thinking that one of the settings was the cause but it wasn't. I finally found the cause and that is exiting in full screen mode. So if you have this issue comming back to windowed mode everytime before you exit will keep this issue from appearing.

 

My video card is a GTX660TI running the latest certified drivers.

 

I would classify this as a "workaround," but thanks nonetheless for bringing it to our attention!

MR Bard and LM are fully aware of it and working to resolve.

I have this issue also. I just created a shortcut to the cfg on my desktop and when this happens change (fullscreen) to false. cheers
