I actually took a photo of my pug using my 4G, and my 3D within 20 seconds of each other. They both did really well, but the 3D had a much higher resolution. I could zoom in and see each little hair on his back, whereas on my 4G, I could not.
This was in bright light conditions. My 4G currently outperforms my 3D in low light.
I'll post a photo comparison when I get home.
Personally, I'd LOVE to see your photo comparison!
OP, which games specifically are you playing that perform worse on the 3D?
Then go back to your IPhone, don't care about 3d gaming on my smartphone. Thats what my 360 and DS are for..
