I've just tested one of my projects on the new Nexus 7 (2013) and compared it to the original Nexus 7. On the new N7 there is now significant slowdown in the scrolling of the level (it's a platformer) that doesn't occur on the old N7. I have tried building it with some different settings: With OpenGL ES 1.1 compared to 2.0. With or without "Require GPU". Different target versions of Android. I also tested it on the first Samsung Galaxy S and even though the game doesn't really play well on this device, there were still less scrolling problems on this "ancient" device!
I know it's a pretty new device so I can understand if noone has had the chance to test on it yet. But if anyone has any ideas please go ahead!
