How exactly can you tell what the performance is, given that its been screencapped at a certain fps, transcoded at a certain fps, likely downsampled along the way, etc...?
Because in the video he specifically mentions getting 50-60 FPS when running it without any screen capturing software and at a resolution similar to apple's retina display. RAGE is also supposed to run at 60FPS on the iphone from what I read about it.
