Summary: S.T.A.L.K.E.R. - Major slowdown near anomalies or in
                    high RAD areas
           Product: Wine
           Version: 0.9.43.
          Platform: PC
               URL: http://appdb.winehq.org/appview.php?iAppId=4794
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: wine-directx-d3d
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

S.T.A.L.K.E.R. slows down to 1-2 fps near the anomalies or in high radiation
areas - places with "white noise" special effect.

Game is set to static lighting, medium quality.

This is with GLSL=enabled and OffscreenRenderingMode=fbo. Using 
'WINEDEBUG=-all wine XR_3DA.exe -dsound -nointro -nodistort' command line to
start the game.

Without "fbo" I'm getting bug 7979.
