Depends on the game. I think I'm more sensitive to latency (less able to compensate) than most people. I couldn't enjoy playing Titanfall until I put my Samsung TV in game mode; I would just get hit and couldn't do anything about it playing League of Legends on my gaming laptop with a 4K monitor, but when I hooked up an external monitor, mirrored the screen, and ran a clock, I took photos showing my laptops' screen was behind by 30 ms. I started playing on an external monitor and started to win. I even found I had a hard time with some 1 player games such as Sword Art Online: Fatal Bullet if I didn't run in game mode.

On the other hand, I went through a phase where I did a lot of streaming from my PC to a NVIDIA Shield and an XBOX. Sometimes through wired Ethernet, something through an airMAX microwave link to my other house. Games like Persona 5 and Orcs Must Die 3 were just fine, but I could not play any Rhythm games, which I have a knack for, High-Fi Rush was no fun at all.

My kid plays fortnite using home streaming to an xbox, and says he doesn't notice the latency. I do the same on an Asus ROG Ally, and it's "good enough". I am not a competitive FPV player, but suffer from OCD and notice latency and it tweaks me hard.

I'm playing single player games via Parsec and the latency feels fine. Moonlight is tolerable but Steam streaming feels terrible for some strange reason. This is running two Wifi 6 devices so nothing is even wired. I often use a controller connected to my laptop, or even better use the wireless controller, connect that to the physical device then you bypass the controller latency and only the video has a lag, which is kind of a neat trick if you're close enough to the computer you're streaming from.

The only sorts of games I can't play are things like Binding of Isaac that are super dependent on reaction speeds, but even games like Elden Ring feel fine.

Do you expect less than 7ms? Because that's my latency with Geforce Now. Almost unnoticable.
