--- Comment #23 from Matteo Bruni matteo.mystral@gmail.com --- Created attachment 61033 --> https://bugs.winehq.org/attachment.cgi?id=61033 +process channel, grepped from the whole log mentioned in comment 21
FTR the log mentioned in comment 21 was made with WINEDEBUG=+process,server. I'm attaching the result of a "grep :process:", for convenience.
From my quick look it seems like the game calls
GetLogicalProcessorInformation() and then SetThreadAffinity() to set "fancy" affinity masks to the various threads. It appears to be making use of all 12 CPU threads in the various masks.
