Microsoft will be implementing a specific game-mode into Windows 10 to offer better performance. The game-mode is planned for a public release with the creators update that will be issued later this year.
If you are part of the Windows Insider program, you'll notice that an early beta of this mode already has been implemented.
Microsoft has not yet explained as to how the mode specifically works but likely non-essential apps and software will get lower processor priority or could even be disabled to prioritize the game you are playing. This frees up CPU cycles and memory. The new game mode will not be limited to the Windows Store titles, games that for example run through Steam will also work with the new mode.
I don't need Windows disabling things it doesn't see as necessary. Anytime they do something gaming related it turns into a mess....I can see it disabling fan profiles, gaming keyboards and mice, and who knows what else.
On the high side it may free up a few hundred megabytes of ram and a tenth of a percent of CPU time, but if you're having trouble running a game then those "extra resources" aren't going to make a difference. It isn't like we're talking about rendering or stress testing programs, after all.
ASC's Turbo Boost does the same thing
Its nothing special, and probably adds some layer of control
And like those, this will be of little to no benefit except to those on Laptops or some what lacking Desktops.
