Comment 5 Yan Vugenfirer 2013-04-10 23:29:06 UTC
Removing "Init.UseMergedBuffers". The guest will always try to use mergable buffer (the check if the host suppors this feature remains in the code):


Comment 8 Yan Vugenfirer 2013-04-11 10:40:37 UTC
Removing "Init.UsePublishEvents", will check host settings:


Comment 12 Yan Vugenfirer 2013-04-11 11:24:33 UTC
The change is for drivers for Vista and up. Windows XP and Windows 2003 will have "old" parameters.
