--- Comment #19 from Fever sebastian.fieber@web.de --- This patch https://bugs.winehq.org/attachment.cgi?id=50908&action=diff by Matteo Bruni from bug https://bugs.winehq.org/show_bug.cgi?id=34052 fixes this. It does have a performance hit for me but at last now it is playable when using bumblebee.
