I just purchased the app and it runs well. My current settings are: Main: 800/1000 performance Profiles: Charging/Full 400/800 performance Screen off 400/600 on demand Battery < 25% 200/800 on demand Temp > 50C 200/400 on demand I am looking into at what else everyone is running. I did have some trouble at first when I had "screen off setting at 100/200MHz on demand" and it would not wake up and I had to take out the battery and restart it that way. I have an idea of the scaling is but not sure of the priority settings. I still have not set it on boot yet, I am going to wait about another day or two to see if the settings are stable that it won't crash. Overall. . . . after about two hours I am happy with the purchase. The processor scaling is what gives that 'lag' everyone is experiencing, but with the setting on performance it is really snappy.
