Is it possible that this issue is related in some way to IQualityControl ({56a868a5-0ad4-11ce-b03a-0020af0ba770}) being unimplemented?
No. The resampler is just too resourse-intensive for some games.
See http://www.winehq.org/pipermail/wine-patches/2012-May/114356.html and http://www.winehq.org/pipermail/wine-patches/2012-May/114357.html for two alternative patches and explanation. Please:
* read the text accompanying the first patch, * bring them up to date (if they aren't) and apply one (I don't really care which one) as a band-aid, * then investigate why switching the resampler via the HQBuffersMax registry setting affects the non-audio thread CPU usage in some games (that's what I suspect to be the real bug).
