Which sensor, and therefore how are you achieving cropping?
The CSI2 receiver writes EVERYTHING it receives to SDRAM. (In the case of the Pi5 it does do some processing first, but I don't believe that includes cropping).
If you adjust the sensor registers to achieve cropping, then you reduce the amount of data being transmitted and written to RAM. Or you can increase the framerate to still take full use of the bandwidth available.
Generic cropping is only implemented for the Global Shutter camera (IMX296).
