            Bug ID: 46988
           Summary: World of Warcraft - d3d12 performance
           Product: vkd3d
           Version: 1.1
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: trivial
          Priority: P2
         Component: vkd3d
          Assignee: wine-bugs at winehq.org
          Reporter: cybermax at dexter.no
      Distribution: ---

Probably unfair to compare, but as of late (sorry, do not have a bisected
commit) d3d12 performance in WoW is roughly 50% of that of DXVK w/d3d11

I use these two patches still tho, and have not tried without them:
https://bugs.winehq.org/attachment.cgi?id=64022&action=diff
https://bugs.winehq.org/attachment.cgi?id=63174&action=diff
(If the problem is solved, and these are not necessary anymore, please tell)

Preset 10, water and shadow a notch down. No MSAA (as MSAA is somewhat bugged
with vkd3d... creates seethrough textures some places).

vkd3d:
gpu usage: 32%
fps: 45
cpu usages per core: 0:74% / 1:56% /2-6:<40% (HT threads lower).

DXVK:
gpu usage: 53%
fps: 81
cpu usages per core: 0:82% / 1:73% / 2:64% /3-6:<50% (HT threads lower).

This is with a RTX2070 and Intel i7-8700K

I think there is some problem with the water effects, as when using DXVK it
looks "normal", and effect changes related to ingame setting. With vkd3d it
seems its just "low" that make a difference in appearance.

What kind of logs is needed to provide some useful information about this?
Doing a trace log will fill GB's pretty quick, but i should be able to do a
login and change water effects perhaps, and see if that provides something
useful?
