Bug ID: 45634
           Summary: enabling CSMT ruins performance for rFactor 1.255
           Product: Wine
           Version: 3.13
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: directx-d3d
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

ever since the commit "dd0ea0a61463db83c - wined3d: Enable the multi-threaded
command stream by default" the performance of wine running rFactor is severely
degraded making the game unplayable - intro movie plays fine but then even the
menu navigation stutters. could be one of the cases where CSMT actually hurts
rather than helps. the same performance degradation can be observed on
pre-dd0ae wine when enabling CSMT via registry key.
