--- Comment #17 from Gustaw Smolarczyk wielkiegie@gmail.com 2008-01-27 02:35:04 --- I think, that it's because of better implementation of ntoskrnl.exe. Game thinks that it's running good (there is less stubs) and tries to execute stub function (IoCompleteRequest). However I haven't got newest wine source to check that.
