i would call origin support and ask them what happend to dx 12 and the vulkan changes. why dont it work? seriouusly..
I have the same problem with a r9 290 and fx8320. I have to use ReLive-17.4.2-Apr11 to be able to boot b1 in dx12 mode otherwise I have a black screen with just a mouse cursor from b1 and nothing else. Is there a solution?? Unfortunatelly dx12 gives me the best performance therefore I do not want to use neither revert to dx11 mode.
I want to update my drivers but anything after ReLive-17.4.2-Apr11 does not work with b1 in dx12. I always use ddu and boot in safe mode.
Any help appreciated!
