Doom and vulkan

Just seen a 15-22fps jump using the Vulkan API. Very impressive. That's at ultra 2560x1080. Anyone also seen some good gains?

Averaging 90fps on a oc'd 390 but I cap at 75 as that is monitors refresh.

I did notice that in one area that used to dip to 50 still only manages 55 so i guess it doesn't solve everything.

 
After some more tweaking, actually running at 120 indoors and 90+outdoors. Amazing actually. That's with nightmare mode and 6.5gb VRAM as well. Impressive for the 390 at that resolution.

Oddly, MSI afterburner cant detect frames and the OSD doenst work...neither does FRTC. Pretty cool though.
