Bug ID: 39027
           Summary: Dungeons and Dragons Neverwinter: very slow startup
                    when launching the game for the first time
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

Have installed the game from steam and launched it afterwards.
Starting it took like 10-15 minutes, so i thought it hanged or something.
After that initial start the game launches much faster but it is still pretty
slow like 3-5 minutes.

I see a bunch of these warning on stdout.. like 100 lines every second:
fixme:win:GetRawInputBuffer (pData=(nil), pcbSize=0x1693e7c8, cbSizeHeader=16)
stub!
fixme:win:GetRawInputBuffer (pData=0x2cca0c0, pcbSize=0x1693bb68,
cbSizeHeader=16) stub!

Using WINEDEBUG=-all doesn't affect the loading times.
