and why again did microsoft go with amd? but for those that pretty much are ignoring what the o.p. said i will try to explain it. microsoft didnt need to go with huma to do tiled resources because it was made for tiled resources. it all has direct x11.2 to get it done.

hUMA isn't about tiled resources.

MS' "tiled resources" tech is already being used. It isn't MS exclusive. All it does is keep the high quality of whatever the camera is pointing at. This isn't an advantage for the One.

hUMA is about the CPU and GPU using the same pool of memory and being able to read each others data without the data having to be copied back and forth between the CPU memory and GPU memory. Tiled resources is software that is being used now, but just might not be called tiled resources. They show the same tech in COD Ghosts, a multiplat game.

Sorry, it isn't.

Tiled Resources is a thing only two existing companies have worked on and have patents for, one of them is Microsoft.  None of them is AMD or NVidia.  The other is PowerVR owned by Imagination Technologies.  Neither AMD nor NVidia are licensees for PowerVR's patent technology.

You're mistaking Tiled Resources with Megatextures.  They are not the same.

Tiled Resources are akin to Paint-by-Number.  Where a letter represents a texture image used.  A tiled resource is made up of multiple small texture tile images, 32x32p, 64x64p, or whatever ratio the final image requires.  Tiled resources looks at the entire geometry of a scene and only applies a texture to the visible area.  Ultimately this requires fewer resources, making tiled resources both GPU and memory efficient.

Megatextures require a very large, final image to act as the texture.  Up to 128000x128000.  These textures are then overlaid, one on top of the other.  So as you move, the texture that offers the infocus terrain is more visible.  While this is less GPU intensive, it is heavily memory intensive.     

The Xbox One doesn't use hUMA because the Xbox One uses eSRAM.  The GPU and the CPU in the Xbox One, as in the Xbox 360, can access the same memory but the GPU also utilizes the eSRAM.
