MakCan someonr actually give me a use case for cloud gaming for anyone looking to play games seriously, or at all for that matter. How does this shit even have a market, never seen or heard about it being used except for in advertisements.
There are a few decent usecases for cloud gaming/cloud desktops but esports can't really be one of them without magical internet (minuscule ping to the cloud and consistent download rate), it'd probably be an OK setup if the servers were in the same building.
Cloud gaming is definitely catered towards the normie who can't notice 1ms to 30ms input delay and who'd rather have a small magical box or a tablet and pay a subscription rather than having to buy and upgrade hardware
A decent application would be video editors who need insane hardware and RAM, the input delay isn't critical, that's a huge hassle solved for the company employing that editor
It's also probably very interesting for cybercafes, a lot of the painful work (working with Windows, buying and maintaining hardware) magically disappears, your users could only break peripherals, etc. In the case of TF2: you would only need to install your config once, you could download all your demos from home, admins could peek at your video output to see if you're cheating (not really TF2, right ..?)
