           Summary: older D3D games slowed down after upgrading wine from
                    0.9.15 to 0.9.16
           Product: Wine
           Version: 0.9.16.
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: wine-binary
        AssignedTo: wine-bugs at winehq.org
        ReportedBy: huivzhopu at hotmail.com


I'm using binary packages for Slackware as provided on winehq.org website.

For example, this Tomb Raider 2 demo
http://www.pcworld.com/downloads/file_description/0,fid,4438,00.asp

Inside the game itself, I enable hardware acceleration, 1024x768 hicolor and
fullscreen.

Under wine 0.9.15, the gameplay is smooth without any lag whatsoever. 
Under wine 0.9.16, I have 99% CPU utilization and it feels like only 5 frames
per second.

Turning sound off (from within game), does not help. Also changing settings
(windowed vs fullscreen, resolution, etc) does not change speed at all. E.g. at
320x200 resolution the speed is still extremely slow. I removed the binary
0.9.16 package, re-installed 0.9.15 and verified that game speed returns to
normal. Installed 0.9.16 and again, speed dropped.

Same problem occurs in a few other games, however this Tomb Raider demo is the
only one that I found to be publicly available.
