You can't play an fps with them but they are fine for turn based strategy and similar games. I did some beta testing for google stadia with assassins creed oddyssey when it was still being conceived, and while it was mostly playable (single player game though, I would not consider it competitively playable against other humans), even with my wired 1g fiber connection the service would have these huge drops down to almost 144p quality along with framerate issues.
