performance differences between v10 and v11

Hello everybody!

Did v11 actually become faster compared to v10? Especially with 3D and with very large drawings.

Please, I would like to hear about real life experiences or detailed numbers (maybe in %) and not just quotations from the "new features" list or from the "release notes". I would like to hear about something that has more real value for a potential customer. Thanks.

And does v11 now support Open GL? Thought I saw a comment about that in a german forum, but I guess its not true since I cant find it on the official site.

Regards, Stephan
