FPS Limiter Request Option

[neonsoul]

This option really works in many games positively. For example, Colin macray 2005, tomb raider anniversary, Wipout Pure / Very demanding the emulator games at exhibiting MAx Fps Limit = 20 or 30, are working at full speed on my phone Samsung Galaxy Note 2.
But there are games in which the opposite effect, such as mortal kombat, there the game starts to go slow. Therefore, if only enable this feature in the settings it would be very convenient. Please add this option in the menu emulator.
Another said that the True Color option when you turn affects the performance of some games slowing down the rate of 10-15 per cent. Is it possible to also return this option in the settings?
thank you!!!!!!!!!!!
