[Bug 27467] New: VSync not working - regression

http://bugs.winehq.org/show_bug.cgi?id=27467

Summary: VSync not working - regression
           Product: Wine
           Version: 1.3.22
          Platform: x86
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: winex11.drv
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

VSync is not working with games such as The Witcher and Mirror's edge. I ran a
regression test and this was the offending commit:

winex11.drv: Allow disabling vertical sync using EXT_swap_control.

EXT_swap_control redefines glXSwapIntervalSGI() as glXSwapIntervalEXT() on
the
    current drawable (if any), and glXSwapIntervalEXT() supports disabling
vsync.

I should note that I am forcing VSync with nvidia-settings and not using the
games's in game VSync option. The Witcher doesn't have such an option, and
Mirror's Edge VSync option doesn't work.

Perhaps this behaviour is intentional, but I would at least like the ability to
override it with a regedit entry or the like. The tearing with VSync off is
quite annoying.
