From my testing on the Lyra average fps is around 45fps. But Hispoot who made the cfw has released another LCD driver that should improve refresh rate i have yet to test it.

new screen driver for testing.  
It uses rgb565 mode by default, instead of rgb666 mode, and can use 3bit mode by passing **p\_3bit\_mode=1 p\_dither=1** or **p\_3bit\_mode=1 p\_dither=0**

If you want high refresh rate, you can try 3bit mode.
