Whenever I try to play some DirectX 11 only compatible games a window comes up with the following text: "The program can't start because d3d11.dll is missing from your computer, Try reinstalling the program to fix this problem.
Now I've tried reinstalling the game, updating my drivers and DirectX run-time and such. I've had this problem using two graphics cards now: Radeon 7770 and my newer R9 270X which I bought a few days ago. I used to be able to play these games (Hitman: Absolution, for example) but for two months is no longer lets me. It's been annoying me for quite some time and I've yet to come up with a solution.
Graphics Card: R9 270X 2GB GDDR5 OC Edition
I'm running Windows 8 64-bit
