--- Comment #10 from Dmitry Timoshkov dmitry@codeweavers.com 2007-12-26 07:19:48 --- Wine does not make any effort to use the multiprocessor abilities of your hardware, except that it gathers the information from underlying OS to report it to the Windows applications. That's the responsibility of the OS/kernel to properly schedule application threads.
