Ah yes, you're right. So that won't have much of an effect on performance.. I guess that if you would use a smaller view entity (as in size on the screen), and then render that view entity to a bitmap, and display that on the screen in a scaled panel or something, you could get some performance gain. However, the overhead of rendering again might diminish the performance gain. On top of that, it's currently very difficult to use the result of one postprocessing shader in the next one properly.
