Rock Paper Shotgun’s Alec Meer interviewed Microsoft’s Kevin Gammill about the upcoming Game Mode in Windows 10:
Kevin Gammill: With the Creator’s Update and Game Mode right now, we’re primarily focused on biasing the game versus the rest of the operating system, from a GPU and CPU perspective. So for some of the other system resources, we can get into a roadmap discussion on the next call, but really right now Game Mode is about biasing the game from a GPU perspective so it gets more of the cycles if it’s in the foreground, and from a CPU perspective both biasing to get more CPU cycles as well as avoiding what I’ll call thread contention for the game.
…
At any time a user can call up the Game Bar and enable Game Mode for any title or game they would like. That’s kind of option one. And then at the same time we will have what we call kind of an approved list or whitelist of games that we feel super-comfortable about and we want to enable out of the gate.
…
Kind of the way I look at it is that any increase is a benefit, without question. Even it’s as low as, say, a 2% increase in framerate, if you’re running a hundred frames per second, I will take those extra two frames per second without question.
This is a strategy for getting gamers to switch to Windows 10 and use the built-in game bar overlay for a possible 2% increase in framerate, or a slightly more stable framerate overall. A framerate increase at all is very unlikely, because driver developers at Nvidia and AMD are already very focused on that. I wish the interview addressed the system rebooting in the middle of a game for updates, because that is a real problem for people playing games on Windows today.
