           Summary: Portal lags for a second when creating first portal
           Product: Wine
           Version: 1.2-rc2
          Platform: x86
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: wine-bugs at winehq.org
        ReportedBy: matejcik at gmail.com


when playing Portal, first time i open a portal the game stutters and lags for
about a second.
The lag appears when the portal just hits the ground and is about to open. It
blocks the "portal opening" sample, which loops a couple times before the game
resumes. It seems to be somewhat worse when GLaDOS is speaking at the same
time, but that might just be a false perception (because GLaDOS's voice
stutters as well).
It happens with computer-controlled portal guns too, e.g. at the very start of
the game, where a portal is automatically opened for you in the starting
chamber.

Creating subsequent portals in the same area is OK, but sometimes I experience
the same stutter in the same map a few rooms further. It reproducibly happens
when a new map is loaded.

It happens with any dxlevel setting from 80 through 98. Portal depth is set to
2, i didn't test with lower setting, i will try with 0 and report back.


i checked in Windows and creating the first portal is OK

my system is intel core i5 with 32bit Ubuntu 10.04 and Wine from PPA.
GPU is Radeon HD 4670, binary fglrx driver
i am playing with compiz turned off
