           Summary: Half-life engine's software rendering is ridiculously
                    slow on Intel GMA 945
           Product: Wine
           Version: 1.1.26
          Platform: PC-x86-64
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: wine-bugs at winehq.org
        ReportedBy: richardcavell at mail.com


When I play Half-Life on Wine in software rendering mode, the screen renders
really slowly.  About one frame every five to ten seconds.  What is actually
being displayed is graphically correct, it's just ridiculously slow.  

While watching the screen, the top rasterline is updated to the new frame, then
the one below it, then the one below that, and so on, until the line being
updated reaches the bottom of the screen.  It then starts on a new frame. 
There is no tearing within the middle of a line.  The lines are output at a
perfectly constant speed.  If I increase the resolution, it is slower to update
an entire frame.  My computer is easily able to render Duke Nukem 3D at fast
frame rate, so there has to be a bottleneck or bug somewhere.  People who have
non-Intel graphics hardware don't get this problem.

I suspect that Wine is incorrectly waiting for VSync after outputting each
raster line.  

The problem occurs also with any Half-Life engine derivative (Counter-Strike,
Condition Zero, etc).  Half-Life is capable of rendering in OpenGL, software
rendering or Direct3D, selectable from a menu.

I'm on 64-bit Ubuntu Karmic with all current updates applied.  Half-Life and
Steam have updated themselves. Intel video drivers are version 2.8.0.  Wine
version 1.1.26. Xserver-xorg version 7.4.  Second-generation MacBook using an
Intel GMA 945.

Jaunty uses version 2.6.3 of the Intel drivers, and Half-Life and its
derivatives are basically completely unuseable on those drivers - they're just
too buggy.

I'm happy to perform any experiments that people suggest.  Running hl.exe from
console doesn't give any printf output, since the main Half-Life engine isn't
actually in that executable.
