           Summary: PhysX causes major lag in Mirror's Edge.
           Product: Wine
           Version: 1.3.11
          Platform: x86-64
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: wine-bugs at winehq.org
        ReportedBy: H3g3m0n at gmail.com


When the PhysX option is enabled (setting in the Video Options) in Mirror's
Edge. When 'physics' things start to occur the game starts to get some major
lag becoming unplayable.

Mirror's Edge doesn't make too much use of PhysX (I believe it was on of the
first games with support for it), afaik it's mostly used for enabling
shattering glass to create shards and maybe some bits of paper on the ground.

As such this only seems to happen at specific points in the game. For example
Chapter 1 Flight->Check Point D. As you are running across the bridge, the
helicopter starts to shoot the glass causing it to shatter.

If you continue on to the next area, at some point (when you go underground) it
suddenly returns to normal speed (most likely it has unloaded the previous
area).

With PhysX set to off, there is no lag but no glass shards.
