Laggy geometry window

Stephan you should really use 2.1.5 version, it should be better performance wise than 2.0.5.

But many materials is more expensive to draw now than it was before when have we started to work
towards more modern opengl usage.

We are working more on the performance issues, Björn is re-writing a lot of stuff be able to handle larger
models, and I'm working on OpenGL rendering optimizations.

I think you can change the options somewhere how automatic selection modes are handled.
