Vulkan underperforming - Android

[iagouvat]

I'm on version 1.6.3-228 and see vulkan really underperforming compared to opengl and to 1.6.3 stable.

With dissidia 012 i'm reaching 18 fps on menu with vulkan compared to 30 fps at all times with opengl using the same settings.

Monster Hunter Portable 3rd HD can only make 30 fps at 2x rendering resolution on vulkan, while opengl reaches 30 fps with 3x rendering resolution easily.

Don't know if it's supposed to work like that, even though i've been following the great opengl evolution in 1.6.x.

I've tested this with my Motorola Moto X4, snapdragon 630, 3gb ram, adreno 508.
