Only gullible fanboys believe this tech can do complex physics calculations in real-time.
What makes you think it needs to be done in real time?
Many effects are not actually rendered in real time, but are done in successive passes.
Also...what does an aging character have to do with the cloud? The author had smoked some good stuff for sure.
There is certainly allot of fluff in the article.
So what happens if you throttle the internet bandwith while playing? Are the waves standing still at some point?
How much of the data traffic is for the wave calculations?
Was the aging of characters in Fable 1 & 2 also only possible due to the power of the cloud?
Pretty sure it's not that much different from Battlefield 4 actually.
So if you throttle your bandwidth... Same kind of thing will happen to you in Sea of Thieves as it does in Battlefield 4.
I would imagine they are just sending height-maps, so the servers can synchronise and simulate the waves.
You are probably right in your assumption to a degree.
