the performance cost. If your CAEAGLLayer object is blended on top of layers underneath it in the layer hierarchy the renderbuffer 䏭 color data must be in a premultiplied alpha format to be composited correctly by Core Animation. Blending OpenGL ES content..

the pixels but its frame point size will remain the same. If you look at the backing width and height for the color renderbuffer attached to the CAEAGLLayer using code like the following glGetRenderbufferParameterivOES GL_RENDERBUFFER_OES GL_RENDERBUFFER_WIDTH_OES.. GL_RENDERBUFFER_OES GL_RENDERBUFFER_HEIGHT_OES backingHeight you should see that the width and height of the renderbuffer on a Retina display are twice the values they are on a standard iPhone display. The code you show above should cause nice.. a mistake in looking up the bounds of the OpenGL hosting view rather than using the backing width and height of the renderbuffer. With a non 1.0 scale factor this will cause the OpenGL content to be drawn at half size. To fix this replace the appropriate..
