I hadn't heard of your command stream patches so I found the emails you
were talking about, cloned your repository and tested it today. It does
help but I haven't got any solid numbers yet. But this is what i've got so

I should have mentioned that I'm running this on a quad core (Intel Core 2
Quad Q6600) and was getting 50% accross all four cores compared to windows
65-75% accross the four cores. The interesting thing being that so far in
my single test. WineD3d with multicore disabled is faster then windows with
WineD3d multicore disabled.

use USE_WIN32_OPENGL. I found out what the problem was. I was able to use
WineD3D with Counter-Strike source but not CS:GO on windows. Turns out if
the multicore option is enabled so it uses more then one thread then CS:GO
and CS:S will crash when using WineD3D under windows.

I also compiled WineD3d with your command stream patches and ran them under
windows once I figured out it was the multicore option causing the crashes.

Which now I have no idea how to debug why it crashes when it is using
multiple threads.

Thanks for your time and your reply.
