Bug ID: 54352
           Summary: Performance tanks when looking at occluded part of the
                    level
           Product: Wine
           Version: 8.0-rc4
          Hardware: x86-64
                OS: Windows
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: d3d
          Assignee: wine-bugs@winehq.org
          Reporter: mirh@protonmail.ch

This is basically the equivalent of the missed optimization I had already
reported to dxvk (except wined3d had like half the framerate to begin with).
With the native nvidia d3d9 driver, you barely can spot a difference in the
Mass Effect comm room between looking at the emptiest wall in human history, or
the closed door behind that gives access to the rest of the ship.
With wined3d, I go from like 220fps to ~70. 
Btw there's an apitrace in the thread above, if it can help.
