http://bugs.winehq.org/show_bug.cgi?id=23993

Summary: Batman: Arkham Asylum demo slow frame rate
           Product: Wine
           Version: 1.3.0
          Platform: x86
               URL: http://www.batmanarkhamasylum.com/demo
        OS/Version: Linux
            Status: NEW
          Keywords: download
          Severity: normal
          Priority: P2
         Component: -unknown

One has to jump through the following hoops to run the demo (props to
the appdb howto):

wget  cdn2.netops.eidosinteractive.com/batmanarkhamasylum/BMDemo_installer.exe
rm -rf .wine
sh winetricks gecko dotnet20
sh winetricks dotnet30
sh winetricks gfw
wine BMDemo_installer.exe
cd .wine/drive_c/users/$USERNAME/My\ Documents
mkdir -p "Eidos/Batman Arkham Asylum Demo/BmGame/Config"
cd "Eidos/Batman Arkham Asylum Demo/BmGame/Config"
wget www.glio.net/UserEngine.ini
wget www.glio.net/UserInput.ini
wget www.glio.net/UserGame.ini
cd ~/.wine/drive_c/Program\ Files/Eidos/Batman\ Arkham\ Asylum\ Demo/
wine Binaries/ShippingPC-BmGame.exe

The game runs, but slowly (on my e8400, it ran at 10-20fps at the default
settings during the initial combat scene).

suggests it can do a lot better.
