What functionality will I lose by installing CM on my Xperia Z3?

I am considering to replace the stock rom of my Xperia Z3 with Cyanogenmod.

What are the functions that will no longer be accessible / installable after doing this switch?

For example I heard that Z3 comes with special DRM protected drivers for the camera, so I assume the camera will be worse after installing CM.

What about the Stamina mode to save battery? Will I still be able to use this somehow?

And what about the PlayStation functionalities of the phone?
