This won't work and it's just another topic used to profit from the ICO scamfest.
It's not just rendering, it's basically a streaming service > a computer rendering the game but sending the screen output to another device.
Sort of like Nvidia Shield or Steam Link except it's not done locally, but remotely so that means that people using the service would need very fast internet and even then it would have huge latency (compared to local network).
The whitepaper argues that most people can't play games with the highest settings but the video feed would have to be compressed to a degree which means a maxed out game will look like it's on low settings. An uncompressed video feed would require very fast (as in high bandwidth) internet.
The nvidia shield for example requires "50 Megabits per second – Recommended for 1080p 60 FPS quality" (
source) which is easy to get on your local WiFi which probably have 70-100 Mbps speeds. Now people would need 50Mbps internet connection. And don't even dream about 4k...
And miners would also have to have that much upload speed
per game they're "mining" AND they'd have to have the other specs of a game met (CPU/memory/disk space) so it doesn't scale at all.
And most importantly, you simply can't render games in a decentralized manner (there's no way to break rendering down to chunks in existing games) so only 1 miner could render a game for someone else playing. That miner could stop anytime losing progress for the gamer. The gamer would also want to play games on his account which would be hard to hide from the miner who would be running the game.
The whitepaper also says such delusions as mining would be
• 2-3 times more efficient than any altcoin mining add opportunities;
• More stable in the short, medium and long term than cryptocurrency mining;
Which is just nonsense.
And even if the impossible would be done and more computers could collectively stream the same game for 1 person playing in a decentralized manner, one miner having a lagspike or any short issue would surely create visual glitches. But again, you can't render games in real time without the whole game running so it's a moot point.
