[size="3"][b]v2.1 STBR[/size][/b]
-Modified and edited hardware files for project butter like smoothness. Touchscreen is way more responsive and more sensitive than before. Touch works fine even while charging
-Activated screen state scaling. READ CAREFULLY. Default governor is set to hotplug(tweaked) but when you lock your phone governor changes to powersave running at 100MHz for amazing battery saving and longevity. Music everything plays great.

My Personal Settings

-Set Background Process to 3

-Tick Force GPU rendering

-For smooth performance and battery life set:

*Max Frequency - 1.3 GHz

*Lowest Frequency - 100 MHz

*Governor - Hotplug (Hotplug governor is tweaked for better dual core handling. Switches off CPU1 faster than before)

I/O - SIO

Activated Screen State Scaling for battery life

------------------------------------------------------------------------------------

According to me switching off a core saves more battery than running at lower frequency with both the cores running
