If this is bad, what about quad hd or quad^2 hd? We're going to have trouble scaling rendering very far above hd. 
Is the Retina display holding back iPad graphics?
The new iPad's Retina display is certainly a sight to behold, but does it come at a cost? That's the impression you'd get from viewing screenshots of Gameloft's new shooter N.O.V.A. 3 over at NeoGAF — the results suggest that the developers have seriously dialed back the effects on Apple's latest tablet in order to push four times as many pixels. The A5X system-on-chip inside the new iPad is more than capable on paper, but what happens when its quad-core GPU is tasked with running a modern first-person shooter at 2048 x 1536? We took a look at N.O.V.A. 3 and some more of the iPad's most taxing games to see how this year's model stacks up to its predecessor.
