Neither the Vulkan renderer or the fallback system seem to be working.
If I have retroarch and PSX in Vulkan mode, it crashes. If I switch retroarch to opengl, it crashes. If I switch both bad to opengl, it works fine.
ParaLLEL works for me, so I know Vulkan is working.
I have an AMD R9 285 with the latest drivers (16.11.4).
