The guy here actually quantifying the problem with pmap, was indeed also reporting how wined3d (once pulseaudio is fixed) gets numbers perfectly aligned with windows now.
This would mean that if the problem is really affecting you much, you are probably using DXVK or Nine (thus it's not a problem for this bug tracker anymore).
It would be nice to know what change was responsible for this improvement though.
