I'm rendering a GL_POINTS image in a GLKView with width & height = .25, meaning it has dimensions equal to a quarter of the screen's dimensions. I would like to make its dimensions match the screen's ones, i.e. 4 times bigger than they are now. I managed to do this setting the points' gl_PointSize to 4. (was 1.) and modifying the x & y appropriately, but this makes the rendering about 16% slower: is there a faster way to achieve the same result?
