Honestly there’s juuuuust enough latency and occasional streaming artifacts that it just got on my nerve. I’m super sensitive to stuff that that. Also my internet generally is good enough, but my actual LAN isn’t great, because I’m too cheap to upgrade my networking equipment. I’ve got gigabit fiber to the house, but I’ve got a rats nest of cat6 through my walls, a bunch of unmanaged switches, and a mesh WiFi setup, some with a wired backhaul, some wireless (because I wasn’t able to get Ethernet to those rooms), so things like game streaming just don’t work that well for me.
Plus like I said, it just feels less wasteful to put my PC where I’ll actually use it. And it’s not like I’ve abandoned my steam deck; I’m just not using it to even try to play big AAA 3D games anymore because I don’t need to
I really can’t imagine jt be that bad. It should just be an occasional ping, unless you want to track on demand. At least that’s how the Apple Find My ecosystem works. If I don’t check a device’s location, it doesn’t ping for hours, but then if I want, I can watch a device in real time (impacting battery of course). I’d imagine google’s implementation will be similar
