I am getting a black screen starting the sim. Both the GUI and the Multiplayer Client. When starting the Single Player mode, I can hear music, however, nothing but a black screen. I have attempted both the Open Beta install and current build, and the same thing happens. The only change recently on my system was going to a GTX 970 from a GTX 760, with updated drivers. Have attempted the repair function and still having issues. Have also tried rolling back drivers and is not working. A system restore did not work. All C++ redistros are updated as well as DirectX. I have reinstalled DCS and also deleted the saved games folders.
Specs: i7-4790K, 16 GB Ram, GTX 970 Superclocked w/4GB VRAM. Win7 64bit.
