Summary: Dual-core not being correctly supported
           Product: Wine
           Version: 0.9.22.
          Platform: Other
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: P2
         Component: wine-kernel
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

I'm running Wine on Ubuntu Dapper with an AMD X2 Dual Core. The Linux kernel is
2.6.15-27-amd64-generic SMP, so both cores are correctly detected and made use
of (I can confirm this with System Monitor).

While Wine itself does seem to make use of the second processor, the emulated
application does not. I can be certain of this because the program I'm trying to
run is a rendering application (Cinema 4D) and I can only see one rendering
thread, whereas two were seen on Windows with the same hardware. I have been
told that perhaps Wine is not correctly informing the emulated application of
the existing hadware.

I have submitted this bug as "major" because this is seriously impacting on the
performace of the application. This probably extends to other similar
multi-threaded applications as well.
