16.12.2 WHQL drops Vulkan performance with Doom

I just upgraded from 16.12.2 beta to 16.12.2 WHQL and the performance of Vulkan Doom 2016 dropped in half using my system.

My initial FPS were at ~110 fps using 16.12.2 and now using 16.12.2 WHQL dropped ~55fps.

 

So, it seems that the CPU utilization of my Core i5-2400 dropped also in half and that doesn't seem like a coincidence.

 

Did you change something internally in the Vulkan API because the version is exactly the same.

 

My system is Win 10 x64 - RX 470 - 16.12.2

 

I went back to 16.12.2 beta and everything is OK now, I'm back to my ~110 fps.

 

Please, fix that Vulkan issue ASAP or at least explain why the CPU usage of 4 core system went down to half (and so did the FPS)

 

Thanks!
