Scaled versions of the game look good, and surprisingly don't seem to impact performance.
There are android tablets out there with greater than 1024, we currently dont support these as we dont have time to test them.
Actually - just had an idea - it might be possible to write a quick speed test in C2 when the app starts up (e.g. move a sprite with some effects), and if it gets less than say 10 fps then put up an unsupported message.
nutmix, sticking to iPad: Do I use 1024x1024 with Crop? Will it scale on iPad3? What size do I put as layout?
