           Summary: Portal slows down when looking at an open portal
           Product: Wine
           Version: 0.9.61.
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: directx-d3d
        AssignedTo: wine-bugs at winehq.org
        ReportedBy: ambro at b4ever.net


In Portal, there is a severe slowdown most times when looking into an open
portal or at a distorted window (from smooth to 5fps).
There are a lot of these messages:

fixme:d3d_texture:IWineD3DTextureImpl_PreLoad Texture (0xf2d8050) has been
reloaded at least 20 times due to WINED3DSAMP_SRGBTEXTURE changes on it's
sampler

If I comment out the reloading code the slowdown is gone, but that causes the
elliptical part of the wall behind the portal to be brighter when it's opening.

Card is Nvidia 8800GTX, driver 169.12.
