Appears that this is two separate issues. The DX11 errors I believe I have resolved by rolling back my AMD drivers to 17.7.1 with a clean install. However, my controller is still randomly disconnecting and acting dead occasionally. Even though it works when I alt-tab out and test it on something else. I can hear the beep when I unplug and plug it in too. If anyone knows what this could be caused by please let me know.
