            Bug ID: 41967
           Summary: Guild Wars 2 - periods if immense lag and stuttering
           Product: Wine
           Version: 1.9.23
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown

In Guild Wars 2 I experience periods when the game starts to lag and stutter so
badly that I can't move or take any action. FPS will drop to 1-2 and even sound
will stutter. With normal wine, this also heavily affected the intro video
after character creation to the point several of the voiced lines were
unrecognizable.

While lowering graphics will increase FPS in normal periods, it has no effect
on stuttering periods or the frequency of their occurring..

The issue might possibly be related to sound, as I noticed several times that
stuttering seems to coincide with a sound effect being played for the first
time, or a character starting to talk for the first time. Other times however
it seems to not coincide with any sound events noticeable to me.


As suggested, switched to wine-staging and enabled CSMT. Results:
 - Intro video is not affected anymore
 - Stuttering periods appear less frequently, but they still do, and when they
do they still make the game unplayable until they end.

As suggested, also added a registry entry specifying my video memory, but this
had zero visible effect.

Using proprietary nVidia drivers.
VGA: GeForce GTX 750 Ti
CPU: Intel Core i7-2600
RAM: 16 GB DDR3 1333 MHz
System: Arch Linux 64 bit, fully updated


Don't know what logs I should attach or where to find them, please let me know
what you need and I'll add them.
