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 far: https://docs.google.com/spreadsheet/ccc?key=0AmPNQYtpuejodDVQc2ctc084cjVISE5NVUd2ZC03MVE&usp=sharing

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.

I followed this guide (http://wiki.winehq.org/WineD3DOnWindows) so I did 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.
