> The OS takes 30 percent of the processing power with a game running? That's crazy if true. It would show how silly the whole idea of "one OS everywhere" really is. It would be much better to have a more stripped down OS that just does the basics and gets you inside a game, and then gets out of the way, instead.

Isn't that 30% made to take care of the social features, like "sharing a clip of the last frag I just achieved" in a FPS or something like that ? If you want to have these advanced features, you need a number of tasks to run in the background and I would not be surprised by the 30% CPU time.

It's not just the social stuff - from my understanding it's running a modified Hyper-V to capture the core console OS. Presumably this segregates off the ability to do background downloads, implement the encryption for HDMI, and so on and so forth from the XBox gaming portion.

If you believe the rumours Dave Cutler worked on the hypervisor of the Xbox.

I don't know what the breakdown is (what number of cores goers to OS,number of cores for the games), the the Xbox One has a rather low performance 8-core AMD unit; the cores are provisioned amongst the OS and games as needed.

Since the CPU is low performance, the OS could easily eat 50% of its total performance, leaving scant little for games.

It'd be interesting to know the figures for the PS4 - whether the OS has a significant footprint or not when games are running. Is there any source for the PS4 available anywhere?
