Just wondering if anyone has been streaming games from their desktop and how it works when they put their Deck to sleep.

I am thinking about building a new desktop, but I almost exclusively play on my Deck and so it would primarily be for streaming to the Deck. My main concern is that the game will continue to run on the desktop either using a lot of electricity or causing me to die in game. I play several Souls-like games that don’t allow you to pause and will often have to break away to do something else at a moment’s notice.
