Yes, that's definately the problem, speedwise, with A6's views, they are fully rendered views. If only we could do stuff with the resolution for each view individually and stretch it out or stuff like that. In combination with the no_render flag or whatever it's called, it's possible to get higher speeds. Still, at the moment only full screen post processing done by a shader on a entity in front of the screen have low frame rate impacts, but off course I could be doing all kinds of things totally wrong here ...
