Summary: Grand Prix Legends: heavy randomic slowdown at 800x600
                    resolution or higher
           Product: Wine
           Version: 0.9.43.
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: wine-opengl

        ReportedBy: [e-mail]

When I start Grand Prix Legends 2004 Demo at 640x480, the game runs fluently at
36 fps like it does under windows, but if I change the resolution at 800x600 or
higher, it runs at about 1 fps and at the same moment the cpu usage goes to
100% (at 640x480 is at 20-25% maximum). This happens in a randomic way because
sometimes it switch correctly to the higher resolution and in that case it runs
fluently even at 800x600 (I've seen this case in 3 or 4 cases over more than 30
times I tried to switch to this resolution). However I've never been able to
run at 1024x768 as I normally do under windows.
