--- Comment #4 from GyB gyebro69@gmail.com 2010-04-16 23:00:12 --- Created an attachment (id=27392) --> (http://bugs.winehq.org/attachment.cgi?id=27392) terminal output from the demo
The reported slow performance is no longer exist in the game, tried the demo with Wine-1.1.43. The value of 'err:ddraw:PixelFormat_WineD3DtoDD Can't translate this Pixelformat' now changed to 58 and 64.
However, there are other issues with the game (it occasionally crashes while loading, missing progress bar on the loading screen) but those need another bugreport. The slow performance was cured somewhere around Wine-1.1.39 but i had no time to track down precisely. Prior to 1.1.39 the demo always crashed for me while loading.
To sum it up: the performance issue is fixed now, and the game is playable.
