will there be any support for vulkan api?

Seriously, i'm on amd card and UE4 scks on amd platform.
Although if we can have the Vulkan, it will be a big boost for this card.
Or else for me(and many other with amd cards) coop is the only playable(where we can get kills) mode.
Btw my cpu is core i5-8400 and gpu is rx460 with 16gb ram and display is Dell 24" full HD IPS display(with 8ms response time).

I don't know if it's a about Vulkan, but I have low performance too with an AMD GC (R9 380) and even if my CPU is quite a good one (Ryzen 7 1700X OC)
