Bug ID: 35633
           Summary: Risk of Rain has low fps
           Product: Wine
           Version: unspecified
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]
          Reporter: [e-mail]

Game gets around 30 fps on menu. Drops to under 10 fps in game. Since the game
is hardcoded to 60 fps, this makes the game effectively unplayable

Some information from test reports:
> Low fps - by default it is unplayable due to several context switches to wineserver per GetLocaleInfoW call.
> Running pinned to a single core (taskset -c 0 wine Steam.exe) gets it to playable but a bit slow.
> http://pastebin.com/uwxftAmk is a possibly thread-unsafe hack to cache some bits that gets it to full fps.

I haven't had the time to get any more meaningful tracebacks yet, and I'm not
sure which debug channels would be most helpful.
