            Bug ID: 59273
           Summary: bad d3d streaming buffer flash range tracking
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: d3d
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

In Dungeon Keeper 2 I noticed bad performance due to:
> fixme "Doing a copy of a mapped buffer (expect performance issues)"

I took a perf trace and most of the time was spent copying 512KB of streaming
buffer back and forth just for a few vertices for every DrawIndexedPrimitive.

It always maps the whole streaming buffer even though it tracks the changed
parts and flushes them correctly:

wow64_map_buffer does skip the copy if you use GL_MAP_INVALIDATE_* flags but
wined3d fails to properly set these flags.

But then you still have the copy at unmap which happens cause it doesn't track
the flush range calls done by wined3d.
