"Gaming" isn't a single activity with a single threshold above which latency is unacceptable. Competitive FPS players will probably never find streaming latency acceptable. A child playing roblox probably always will. The rest of us land everywhere in between.

If you have a specific use and requirement you'll pretty much need to try a streaming game service and see how it goes. There are several of them these days and they often have free trials so it's not too ridiculous to just sign up with one and see.
