            Bug ID: 47897
           Summary: AMD Mecha Demo is miss-rendered (and extremely slow)
           Product: Wine
           Version: 4.12.1
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: directx-d3dx11
          Assignee: wine-bugs at winehq.org

Demo run under Wine

AMD Mecha Demo, uses DX11 and demonstrates use of OIT (order indepdenent
transparency), using per-pixel linked list. To implement it, demo uses atomic
counter in shaders.

Reproduced with Wine Staging 1.12.1, with Mesa 19.2.0-rc2, and Mesa
19.3.0-devel.

Demo works correctly when run using DXVK 1.4.1.

Before starting the demo, I suggest editing a Sushi.ini file to reduce
resolution and make it windowed. Even then you might need to kill it if it
becomes extremely slow.
