Hardware-accelerated encoding, compression, frame rate, data rate

I am wondering what kind of framerate I can expect with what kind of hardware at Full HD resolution (e.g. Lenovo Tiny vs Raspberry Pi) and with what kind of data rate.

Does Deskreen compress the video at all?

Is hardware-accelerated H.264 encoding planned/feasible?

VNC, RDP, Guacamole and NoVNC do not do compression, it seems:
