This should be a given imo.

I would take fergs word as the truth. Sounds like the one guy is doing damage control by tired of hearing old xbox owners complain.

If it has a newer CPU/GPU it will boost performance, that is inevitable. The question is, how much? If an X1 game get's 56 FPS, the XB1 S may (hypothetically speaking) get 57-58FPS - hardly anything to write home about :) You'll get more benefit from the 4K upscalling and HDR. It's not as if this console will suddenly make everything 1080P/60FPS haha

Huh? What magic mysteriously converts your standard 24bit game assets into 30bit assets?

Not magic, so far only 3 games have been confirmed to take advantage of 10 bit output. The game must already be rendered internally in HDR. A lot of 3D games use HDR rendering in fp16, 16 bit precision floating point.  Normally a small range of the output gets downconverted to 8 bit color. The XBox One S can also downconvert a bigger range of the fp16 source to 10 bit color.

But you're right, if the game assets aren't all made with HDR in mind, they'll stick out like a sore thumb. That already happens with 4K UHD movies, for example Mad Max in 4K HDR has very fake looking fire effects in HDR.

But the combination of HDR and enhanced resolution is not an unalloyed benefit. Anyone accustomed to watching classic films on Blu-ray should be familiar with the phenomenon in which such staples as matte paintings, rear projection and painted backdrops became obvious, sometimes distractingly so, with the increased sharpness and resolution of 1080p. Something similar happens with certain visual elements in Fury Road. The most common culprit is flame, which frequently accompanies the action, whether as weapon, decoration (notably the Doof-mobile) or the outcome of some spectacular crash. If you watch the extras on the Fury Road Blu-ray, it's obvious that the film's flame effects are a combination of practical and CG, but on the UHD almost every flame looks like a painted cartoon. Just as the enhanced depth and detail are pulling you into the film's ravaged wasteland, the artificiality of these effects pushes you back out. The same is true for the fierce dust storm in which Furiosa first loses her pursuers; in its theatrical and Blu-ray presentation, the storm was convincing and credible, but on UHD one is struck by the obviousness of the computer imagery.

So I guess it will be added on a game by game basis, and so far Gears 3, Scalebound and FH3 will be the only ones to support 10 bit output. It will be interesting to see how it pans out for games.
