--- Comment #12 from Roderick Colenbrander thunderbird2k@gmail.com 2009-03-29 15:43:53 --- I have submitted a patch. Second when running on virtualbox I recommend to compile using -DWINE_NO_DEBUG_MSGS to prevent checkGLcalls in wined3d. Those calls call glGetError and they might be very expensive on virtualbox.
