There are quite a few attempts to that topic (Parsec Gaming, Shadow Gaming, ..)

I tried a few of them but as for latency relevant online gaming current solutions are rather meh.

For an old laptop I guess its alright and price for casual gaming is probably hard to beat (if renewing every 3-4 years hardware). But as with any cloud/rental after paying its gone.

Most of the initial innovations seem to be in the hardware, e.g. controllers that hop over your PC/console, game servers in edge nodes, etc. They're incremental improvements, but my latency on Stadia gets down to single-digits at times (though is usually low-mid double-digits), which is something I never saw with OnLive (not a direct comparison since I have better Internet now).

There's some interesting software innovations that may or may not be implemented (I'm not sure?), but I haven't heard of other streaming platforms doing things like running games at significantly higher framerates (to minimize the time between player input and game response) and predicting button presses to buffer a stream before they happen. Those seem like innovations in the space, even if they're under a terrible umbrella of a name ("negative latency").

> predicting button presses to buffer a stream before they happen

That sounds a lot like the server and client-side prediction (or p2p 'rollback') netcode that is in a lot of online games.

AWS Appstream has been around for many years and its pretty good. This presentation is from 2013.
