Tiled resources are not a way to store more textures, it's a way to quickly access larger amounts directly through hardware by streaming only the necessary textures instead of the whole thing. This is a technique that is also in OpenGL 4.4, only it's not called by the same name.

How it would theoretically work with the cloud is that you would only need to load what you use into ram instead of having to stream the entire texture and all of it's smaller MIP maps. However the problem comes with streaming from the network to the DDR3 ram, the bandwidth bottleneck is too huge with the network. The memory footprint for textures would be quite a bit less but you still have the network to deal with (mega bandwidth issues) and there is no reason why you couldn't also do this with a local storage like a harddrive or a blu-ray disk. You'll stream faster and much more stable from local sources. The cloud would only give you the ability to have more unique data since you're not bound to a single source.

So you're throwing out information without being able to comprehend what you're saying. You don't store that 6 gbs of texture data within the 32mbs of ESRAM, you just used tiled resources to stream what you need instead of loading in the full range of data that is traditionally processed. It's just more efficient and helps them deal with that bottlenekc.

That's not going to make up for the fact that the Xbox One's GPU is weaker at pushing polygons, shading pixels, rendering effects, and having to deal with the bottleneck that is the ESRAM in the first place. The only thing this does is more efficiently stream textures to the GPU for rendering on the frame. This is also not unique to the Xbox One. OpenGL 4.4 has a very similar method that is as powerful or more powerful which will be included with the Playstation 4.

OpenGL has included this. In fact from what I'm reading, just like most DX features ever, OpenGL saw the first implementation while Microsoft took the feature from OpenGL and implemented it into DirectX.

The Xbox One will benefit more from tiled resources because of that dumb ESRAM limitation. The PS4 has no such bottleneck but every machine always benefits from having to process less data. It's a win-win for both.

The Xbox One's 1080p problem is still going to be a problem as it takes power to render all 2 million pixels of 1080p. That's power the Xbox One does not have compared to the PS4. As developers want to push more polygons, better lighting, and better shading you eventually need to make a sacrifice. They'll be making more sacrifices sooner on the Xbox One than they have to on the PS4.

Please don't say you owned me when you have no clue what you're talking about.
