Game-Mode is reported to work on any game. (Not just Microsoft)
More on Windows 10 Game-Mode.

This is giving me a hunch if MS has finally come up w\ an algorithim to optimize a game using CPU priority\affinity (assign a specific game's threads high CPU priority then assign all other running apps threads a lower priority than "normal" to gain as much CPU processing time as can be gained for a specific game then use CPU affinity to gain the rest if needed.....from a CPU perspective)......or licensed someone else's algorithim to do the same........like Process Lasso's?
Hmmmm...................
The GPU side is the main issue of contention (the main reason why this hasn't already been done in prior Windows versions) as for the OS to actually gain control of the discrete vid card's GPU to do the same the IHV's have to allow the OS to gain some direct access to the GPU hardware thru their drivers.........which would essentially mean that the OS would "need" a universal "driver" that will work across Nvidia, AMD & Intel GPU's..............
Now since MS has developed Dx12 from patterning off AMD's Mantle API it would be logical to assume that AMD "may" just rewrite a version of Crimson driver stack to allow MS to attain this access in Win 10 as an "update"..................?
Just thinking out loud...............
