[2022] To host or not to host?

Originally posted by Spiritual Squid: May be a silly question, but would me hosting the game for my friends effect performance for me? Games fine other than on horde night which I understand as my rig is a bit on the outdated side. Would my It be better if buddy with a monster pc acted as the server?

Yes and yes. Hosting the game and running the client on the same machine adds to the load on your system, speaking generally. The system requirements on the store page mention this.
