you have some experience with rpi2, opencpn and OpenGL and you wrote me somthing in the oc-forum. But I´ve still some questions.
I now solve some other probs with my pi2 and now try do get opencpn with OpenGL to work.
The first attemps wasn´t sucessful. With the new jessie and experimental pis Driver I only get round about 1-2 fps in OC with OpenGL switched on. I used the ready build packages.
Do you build oc from source when getting more Speed under OpenGL?
How do you get more grafik power?
