Friendly reminder that wined3d is just slow because it sucks with buffer management, not because opengl has any particular unholy fault.
It is the supposed equivalent of all microsoft's apis up to 11, after all? If any dxvk benefits of a way more "normal" labour (then vulkan surely helps delivering lower cpu usage, but it is not like that should make the difference between playable and slideshow)
Of course you ain't getting any of it, if the last binaries you have available are so ancient they lack any glimpse of csmt, pba, esync, and staging.
p.s. I was under the impression there was some kind of vulkan driver for nvidia cards?
