Disappearing Act

I am not sure what is going on or why it is happening all of a sudden, but my VC panel disappears as well as all outside graphics just after takeoff. I first noticed it with PMDG 737, but then I tried with default aircraft and it happened too. The panel just simply disappears and all other views are not visible except for the 2D Panel texture. I have not changed anything since my last successful flight before the holidays, the only addition is REX SF 3D. I have deleted my .cfg and shader files also just to see. Everything works fine on the ground, just once airborne, they vanish. Honestly, I am getting tired of having more issues than I fix. More of my time is spent troubleshooting issues in this game than it is flying. My only other option would be to uninstall and reinstall the game, but trying to avoid that if possible. I haven't run across anyone posting about this issue so not sure if there is a fix for it. I'm not asking for much, just for a sim that works when I need it to!
