Thank you Chris! So, im guessing that "block-on-vsync" basically does the same thing as vertical-sync but they sync in different ways?
As i understand from "http://openscenegraph.net/pipermail/osg-users/2006-March/062743.html"; the "proper" way to get vertical-sync and to keep the program from eating all cpu-power is to call the function that you described and add an glFinish() at the end of my rendering loop or did i get everything wrong?

I think that the 'v' key actually toggles "block-on-vsync", a different condition.
