Is presenting a video feed faster with GPUImage?

I need to get video from the iPhone camera and present it to the user (I do some UIView overlays) Do I get more FPS with GPUImage without any post processing?

Thanks

    "I don't know of any hard limit for framerate internally, unless you're rendering to the screen at some point. The screen might cap a refresh rate at 60 FPS when presenting the render buffer. This could potentially pause the OpenGL ES queue at that point if rendering faster than 60 FPS."

    Here is a nice article on GPUImage. Don't forget that the FPS will var between various iPhone types.
