No, I haven't got any profiler statistics, but I can try to get one if it
helps. I will need a guide how to do it though.
There are several reasons I'm blaming DIB engine for slowness.
1. First I reported this bug #12612. As an attachment there is a console output
from Heroes IV under wine. Roderick Colenbrander kindly answered my questions,
and directed me to this bug report and this wiki
http://wiki.winehq.org/DirectDraw.
2. I found this bug #3902, which is tagged as CLOSED and FIXED. While the fix
was released and the author claimed it worked, the fix was rejected due to
regression bugs (see comment #14). So the problem stayed.
