We should note, this is entirely a Nvidia software imposed limitation, as the hardware can easily handle more, the purpose is to upsell to non-gaming cards.

With that being said, its trivial to bypass with tools like: https://github.com/keylase/nvidia-patch

Regardless, this does throw a spanner in the works for a video based game streaming solution for P2P multiplayer.
