Hello Manivannan,

You should get 4K at 60fps is you are using MIPI, maybe you are doing something wrong, also please update your linux BSP to L5.4.24 to have better performance:

actually i have done the following settings like this for adding vivante in the build , does this is causing any slow in camera applications, otherwise where should i look to find the reason for slow camera responses.
