I'm interested in comparing the performance between it and DXVK on some games I'm testing, especially those where DXVK seems to provide almost no benefit (or sometimes even worse performance!) over wined3d, which is a bit odd. I've seen numerous claims that wine-pba provides even greater performance than DXVK on certain titles, so I'm curious.
The PBA patchset is a wined3d patchset. It doesn't have any influence on DXVK.
If you're interested in doing performance work though, I'd argue it would be more interesting to try to close the gap for those cases where DXVK is currently faster than wined3d. It's great that DXVK is working so well for some people, but it's also ultimately a dead end.
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 wined3d.
On the subject of PBA, I'm not aware of a more recent rebase, although that doesn't necessarily mean there doesn't exist one. Matteo has a set of patches using a somewhat similar approach that you may find interesting though. Those aren't publicly available, but he may be willing to let you have a look if you ask nicely.
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?
