With the "right" combination of application and GPU, quite possibly. However:

  - It's always good to have some data to back this kind of change,
even if only for future reference.
  - I think it's a little harder than this patch, unfortunately. In
particular, we track "bind_mask" per texture, not per sub-resource. So
if after this patch we e.g. were to first call
wined3d_texture_vk_barrier() for SRV usage of one level/layer of a
texture, and then subsequently for a different level/layer, we
wouldn't create a Vulkan barrier for the second call.
