--- Comment #18 from Roderick Colenbrander thunderbird2k@gmail.com --- Can you run your game using WINEDEBUG=+process? I'm curious about some of the cpu related calls the game makes. I think you provided a log like this maybe on IRC, but I don't have access to it.
I did a quick audit on the Wine code and there are definitely some missing things, which look a little suspicious, but I don't know if the game uses it.
For example ntdll/nt.c has TODOs in 2 sections dealing with filling out SMT related information in logical_proc_info_add_by_id. This is ultimately used by GetLogicalProcessorInformation/GetLogicalProcessorInformationEx.
