After The Witcher 3 which was flawless (the remote machine's performance I mean, not the streaming, my net sucks) I also tried Kingdom Come to really stress it and on higher settings it went down to 30 fps or less so I guess they don't quite give beastly power to freeloader accounts.
I also tried that one on my phone instead and the whole interface was different though so I wonder if they also give different kinds of power levels when you access stuff on touch devices thinking that maybe they should also tone down settings as small screens can't see better anyway?
Lag was more evident, maybe because of this being first person (and also having very weighty character control and such to begin with, iirc, it's been a while since I played it), maybe because the Wi-Fi on my phone is even worse than on my PC, I dunno. Mouselook on Witcher 3 was great.
