Because if the PS4 is able to do the same without the cloud then it shows what little impact it has.
I don't really get what that means. Honestly i'd at least expect it to make 60fps more feasible with 1080p games. Something that both consoles are obviously struggling with.
It's been hyped as a major feature yet it has done nothing to meaningfully improve the gaming experience. In some cases it has actually caused issues, like with Forza 5. It's possible developers will suddenly flock to use it and do so in a meaningful way but we simply haven't seen any evidence to support that. If it was a major feature, something that differentiated the XB1 from the PS4, you would expect to see it being used more.
For now it's nothing more than a gimmick. That might change.
I don't think developers have even had a real chance to work with it. So I guess anything is a gimmick before it's actually used. You're making finite judgements based on something that's only barely been available. Just like everyone here who seems ready to call the console war based on the first few months, where last gen it seems everyone was helping the PS3 limp along until they were praising it in the last 2 years of an 9 year long generation. I'm so tired of this double standard.
That remains to be seen. We saw a lot of hype surrounding streaming games (OnLive, Gaikai, etc) and yet the actual experience was a complete letdown.
Because it's all theoretical - we haven't seen any worthwhile real world implementations. Anyway, I think I've made my point and I don't just want to keep repeating the same thing. It is a technology that has potential and could theoretically lead to worthwhile improvements to the gaming experience—I don't think that is in dispute—but for now it simply doesn't do that. Even if it works there are problems associated with the approach, like latency spikes and connection interruptions that could negatively impact the user experience.
First of all, this isn't OnLive or Gaikai. Not even close. Again, I will point to my above post that such a comparison only demonstrates your lack of understanding of the technology involved.
And no, sending data to the cloud is not theoretical. You're already doing it on this website. Many games already make use of it, and there are hundreds of technologies out there built explicitly for managing such environments in as fast a way as possible. Facebook, Twitter, Steam, any multiplayer game that's peer-to-peer, etc. All these things send data in real time back and forth. So to assume doing the same with some physics calculations is theoretical is ignorant at best.
