RDR 2 isn’t a racing game or a fighter. You could argue it isn’t really an action game.
Also, why do you believe the latency of a display or a controller isn't sequential to the delay on Stadia?
You can see right in the half-assedly-found top YouTube result 11 frames at 16.6ms delay each, so that's 180+ ms of delay, before ANYTHING happens AT ALL on the screen. Much less something noticeable. It'd be very straightforward to shave 100ms off the buffer bloat in one of these games, so Red Dead Redemption 5 the Stadia Exclusive could have the exact same responsiveness controller-to-screen as Red Dead Redemption 2 on a fast internet connection.
I said AAA games, I meant the super big-budget action RPGs that dominate the industry. Obviously well-tuned shooters, racers, and fighters aren't going to play well with an extra 100ms of lag. That said, even super well-implemented games in those genres have a few frames between a button press and the screen unless you're talking VR or something from the CRT era.
Anyway, I have better things to do than try to explain to the Dunning-Kruger Boys how latency works, especially since I hate Stadia anyway and your ignorance will help speed it toward its inevitable doom.
