i recently bought doom 4, i played it for a while with vulkan enabled and i get 19 - 23 fps averages, when i changes to opengl 4.5... i got 32-37 averages. i wanna ask, what's wrong with this? vulkan should gives a huge boost on every gcn architecture...

Your CPU is leagues ahead of your GPU.

As your GPU is the bottlneck, the newer APIs are less effective. The fact it is work is down to un optimised drivers. I don't think you will see an improvement any time soon.
