I have a GTX 660 - which supports DirectX 12 - and the unofficial DX12 branch from a few months ago worked flawlessly. However, in the official branch, it just doesn't work. When I switch to it in the display backend, Dolphin crashes with no error message. Sometimes it doesn't crash at all, but when I get into a game, it either gives me a black screen with sound or crashes (again, with no error). I'm running the latest version of Dolphin as of right now, which is 4.0-9063. I also have the latest Nvidia driver.
