This series doesn't seem Vulkan specific.

There was no drop in GL or GLES version of Aztec Ruins, only in Vulkan version
of AztecRuins (*).  And no drop in other GL benchmarks, so I think the
regression is Vulkan specific.

(*) While Vulkan version runs windowed (because GfxBench doesn't seem to
support fullscreen for Vulkan), and GL & GLES versions are fullscreen, I don't
think that test being windowed is relevant because:
- the other regressing Vulkan tests are fullscreen
- AztecRuins has low FPS

Were you able to reproduce e.g. Deferred Multisampling Vulkan demo drop?
