--- Comment #28 from wineuser sickam@mail.ru --- Tested and compared the game between my Linux- and a fresh Windows 7 setup. I can tell for sure by now, that the poor framerate is caused by the UI, but only on when playing via Wine! When i played the game on Windows it runs smoothly, didn't even see any differences between UI disabled/enabled. Up to 120 fps. However i can also get this framerate via Wine but only when the UI is disabled.
In this case i can only come to one conclusion. Wine does not have a problem with the game itself but with the the UI (again, the UI was made with Autodesk Scaleform - http://gameware.autodesk.com/scaleform).
Maybe someone could have a closer look at this.
I hope that this will be fixed in the future. Thanks so far to everyone.
