high quality mode : 1440x2560 302dpi
balanced mode good quality and good performance : 1200x1600 206dpi
performance mode (very very smooth, quality not bad ): 960x1280 165dpi
after using tab at 960x1280 i can not back to 1440x2560 because is not smooth for me
I don't think this is quite correct. The performance is already there. If I scroll something and let go, the scrolling is smooth. However, if you scroll with your finger still on the touchscreen, the performance drops. It looks like the bottleneck is in the touchscreen drivers. It looks like the touchscreen sampling rate is low compared to my phone (Nexus 4). Turn on developer option and enable show touch position. Draw a line and compare that to your other mid to high end devices and you'll notice the high end devices have nearly twice as much points drawn in between that line.
The settings you provide may be able to speed things up marginally but you won't notice it. The only thing you'll notice is the fuzziness you've introduced by lowering the resolution. Which makes the retina display a total waste. I have mine set at 1536 x 2048 290dpi and it's still sharp and snappy as long as the touch screen isn't constantly pressed.

I just want to add that the recommended settings change will definitely help 3d games, but the OS on its own should handle the native resolution well.
