Yeah, in most case DXVK seems to be indeed faster, sometimes it's slower
though (I don't know if it's my setup, or the game), but I see a lot of
people who test both DXVK and wined3d with pba claim that wine-pba is
actually faster than DXVK by a nice margin (10%-20% or more) in many
cases, which is why I want to test it out for myself. :-)
Since DXVK already uses persistent buffers, it's a much fairer
comparison between an OpenGL backend and Vulkan if we also use pba for

That would be great. FWIW I don't mind if they're hacks at all or in
crude condition, since it's just for testing purposes.
Matteo would you please let me try out your patchset?
