Quick answer

Leave Windows Game Mode on. It ships on by default, gives the game priority and holds back Windows Update driver installs and restart prompts while you play. Dual-die X3D chips such as the 7950X3D and 9950X3D rely on it to park their second die. Test it off only when a CPU-bound game or a background stream gets worse.

TL;DR · Game Mode on or off

  • Almost every Windows 11 gaming PC: on. It is the default, and the 2025 and 2026 tests put averages within about 5 percent either way.
  • Ryzen 9 7950X3D or 9950X3D: on. AMD's core parking runs inside Game Mode.
  • Discord or a browser open while you play: on. That is where the 1% lows improved most.
  • CPU-bound game that loses frames, or a CPU-encoded stream that stutters: test off for that session.
  • Where it lives: Settings > Gaming > Game Mode, a separate switch from HAGS, V-Sync and your power plan.

Leave it on. Windows Game Mode is on by default, it changes little on a PC that runs one game at a time, and on dual-die Ryzen X3D chips AMD’s own scheduling depends on it.

The case for turning it off is narrow and real. Game Mode hands the foreground game priority over everything else, and in a game that already pins the CPU, or beside a stream encoded on the same CPU, that priority can take more than it gives. Those two cases are the reason to test it, and the table below gives the setting for the rest.

This page is about the Windows setting. A TV or monitor picture mode called Game Mode is a different thing on the display’s own menu, and the OLED TV as a PC monitor guide covers switching it on.

What Game Mode does

Microsoft’s support article for the setting is short. When you’re running a game, Game Mode “prevents Windows Update from performing driver installations and sending restart notifications” and “helps achieve a more stable frame rate depending on the specific game and system.” It notes that Game Mode is turned on by default.

Microsoft’s archived developer documentation, written for Windows 10 in 2018 and covering Game Mode APIs that were deprecated from Windows 10 version 1809, explains the second line. Game Mode works by “granting a game exclusive or priority access to hardware resources,” the game has to be in the foreground with focus first, and it works for most Windows games with no action from the player or the developer. The same page lists CPU core exclusivity and “increased GPU prioritization” among those resources, and it sets the expectation in one sentence: “The performance increase that comes from Game Mode is directly related to the number and impact of other activities running on the device.”

A PC with nothing else running has little for Game Mode to take back. A PC with Discord, a browser and a stream running has plenty.

Game Mode on or off, by PC and use

Typical gaming desktop or laptop, one game at a timeOnThe default. The tests below show averages within about 5 percent either way.
Ryzen 9 7950X3D or 9950X3D (two dies, V-Cache on one)OnTom’s Hardware lists Game Mode among the four things AMD’s thread placement needs, and IDC describes the 9950X3D’s parking as working “within the Windows Game Mode power profile.”
Ryzen 7 7800X3D or 9800X3D, or any single-die chipOnOne die, so nothing to park (see the 7800X3D review and the 9950X3D vs 9800X3D comparison). The general case decides it.

Streaming or recording with a CPU encoderOn, then test off if the stream drops frames during playGame Mode favors the game over the encoder. PC Gamer’s 2017 runs showed a background video starved while the game held up.
Laptop on batteryOnMicrosoft says Game Mode can be engaged in any power slider mode. Battery life is the Power mode slider’s job, a separate setting.
G-Sync, FreeSync or fixed-refresh monitorOnMicrosoft’s description of Game Mode says nothing about refresh or sync. That is the V-Sync decision.

The X3D row is the one with a real cost. Tom’s Hardware’s 7950X3D review lists the requirements as “a new chipset driver, updated BIOS, Windows Game Mode, and an updated version of the Xbox Game Bar,” and explains why Game Bar is on that list. Game Bar “detects games and triggers Game Mode” from a known-good list of titles, and AMD’s PPM Provisioning File Driver then parks the slowest cores “when Game Mode or Mixed Reality Mode is active,” which confines the game to the die with the extra cache. Turn Game Mode off on one of those chips and that parking has no trigger. The 9950X3D vs 9800X3D comparison covers the rest of that machinery, including AMD’s per-game compatibility list.

If a game on a dual-die chip does not trigger the parking, Tom’s Hardware notes you can add a game or program to Game Bar’s list from Game Bar’s settings with a single click.

How to turn Game Mode on or off

Microsoft’s steps are Start, Settings, then Gaming > Game Mode, and turn the switch on or off. On Windows 11 Home 25H2 build 26200.9457, read on 2026-10-02, the page’s breadcrumb reads Gaming > Game Mode, the switch’s description reads “Optimize your PC for play by turning things off in the background,” and the only entry under Related settings is Graphics.

That Graphics link is where hardware-accelerated GPU scheduling and Windows’ variable refresh rate switch live. They are separate settings with their own answers, and Microsoft’s description of Game Mode mentions neither.

Microsoft’s steps end at the switch and do not mention a restart. To test it, flip the switch, relaunch the game, and play the same scene both ways with nothing else changed.

What the tests show

No benchmark was run for this page. These are other people’s numbers, each from one or two systems, and the oldest comes from Windows 10 in 2017.

Publication, dateHardwareResult with Game Mode on
PC Gamer, May 3, 2017Core i3-7100 with GTX 1050 Ti; Core i7-5930K with GTX 1080Budget PC minimum fps “20-30 percent higher” in some of six games. A background 1080p60 YouTube video went to stop-motion on the i3 and stuttered and froze on the i7.
XDA Developers, November 18, 2025Ryzen 5 7600X, RTX 4070 Ti Super, 32 GB DDR5-6000, 1440pFortnite 165 to 170 fps, The Last of Us Part II 150 to 155, Hogwarts Legacy 183 to 188. Gains of 2.7 to 3.3 percent in averages.
MakeUseOf, July 12, 2026Core i7-13700H laptop, RTX 4060 Laptop 8 GB, 16 GB DDR5, Windows 11 Pro 25H2, CapFrameXCyberpunk 2077 82.4 to 82.9 fps. Counter-Strike 2 1% low 142.3 to 154.6. Forza Horizon 5 with Edge and Discord open, 1% low 48.2 to 71.5.
MakeUseOf, August 1, 2026Ryzen 5 5600, RX 5600 XT, 16 GB DDR4007 First Light 64.6 to 61.8 fps (1% low 47.9 to 42.3). Assassin’s Creed Black Flag Resynced 52.4 to 49.8 (36.8 to 33.3). Warzone 106.5 to 107.2 (79.4 to 82.1).

Read together, they agree on the shape. Averages barely move. The 1% lows move when something else wants the CPU, and they can move in either direction.

The two MakeUseOf pieces are a fair pair. The July laptop’s biggest gain came with Edge and Discord open beside the game. The August Ryzen 5 5600 desktop ran CPU-bound games with little to clear away, and its author concluded that Game Mode’s “reprioritization disrupted resource allocation on titles already maxing out CPU usage.” That is the one case where I would test off, game by game, rather than switch it off for everything.

PC Gamer’s 2017 result is old, from the Creators Update version that had to be enabled per game through Game Bar. Its warning still matches what Microsoft documents. Priority for the game means less for whatever runs beside it. A YouTube tab losing frames is a nuisance. A CPU encoder losing frames is a broken stream.

How it interacts with the other switches

Hardware-accelerated GPU scheduling. Separate switch, separate page under Graphics. Leave HAGS on for any card that shows it. Change one switch at a time, because changing both at once makes a stutter impossible to attribute.

Power plan and Power mode. Microsoft’s power slider documentation says Game Mode “operates independently of the Windows performance power slider, and can be engaged in any slider mode.” It is not a power plan, and switching it on does not move the slider. The Ultimate Performance power plan page explains why Balanced stays the plan for a gaming PC.

Xbox Game Bar and background recording. Game Bar is the overlay on Windows + G, and on a dual-die X3D chip it is part of how Game Mode knows a game is running. Background recording is a different switch. Xbox Support says the Record last option needs background recording turned on, from Game Bar’s settings or Settings > Gaming > Captures. If a game stutters, MakeUseOf’s July tester puts drivers, overlays and background recording ahead of Game Mode on the checklist, and so would I. The stuttering guide works through that list.

Xbox mode. A newer Settings > Gaming entry. Microsoft describes Xbox mode as “a console inspired, dedicated gaming experience” for Windows 11 version 24H2 and later, a controller-optimized full screen shell. It has its own page under Gaming, apart from the Game Mode switch.

Memory Integrity. A separate Windows security setting, and Microsoft’s description of Game Mode does not mention it. Its on-or-off decision has its own page: Memory Integrity on or off.

Frequently asked questions

Should Game Mode be on or off?
On, for nearly every PC. Microsoft turns it on by default, and the published tests since 2025 show it moving average frame rates by up to about 5 percent while helping 1% lows when other apps are running. Dual-die X3D processors such as the Ryzen 9 7950X3D and 9950X3D rely on it for AMD’s core parking. Turn it off only to test a CPU-bound game that runs worse with it, or a CPU-encoded stream that drops frames.
What does Windows Game Mode actually do?
Microsoft’s support page lists two things while a game runs. It stops Windows Update from installing drivers and sending restart notifications, and it helps achieve a more stable frame rate depending on the game and system. Microsoft’s older developer documentation describes the mechanism as giving the foreground game exclusive or priority access to hardware resources, including CPU cores and GPU priority.
Does Game Mode increase FPS?
Not by much on average. XDA Developers measured 2.7 to 3.3 percent more average frames in three games on a Ryzen 5 7600X and RTX 4070 Ti Super in November 2025. The larger effect is on 1% lows with apps open. MakeUseOf’s July 2026 laptop test saw Forza Horizon 5’s 1% low rise from 48.2 to 71.5 fps with Edge and Discord running. A separate August 2026 test on a Ryzen 5 5600 lost frames in two CPU-bound games.
Is Game Mode bad for streaming or recording?
It can be when the encoder shares the CPU with the game. Game Mode gives the game priority over everything else, and PC Gamer’s 2017 tests found it turned a background YouTube video into stop-motion on a Core i3 and caused stutters and freezes on a Core i7-5930K. If a CPU-encoded stream drops frames only while you play, run the same session with Game Mode off and compare.
Does Game Mode change my power plan or power mode?
No. Microsoft’s power slider documentation says Game Mode operates independently of the Windows performance power slider and can be engaged in any slider mode. Power mode and the power plan are separate settings, and Balanced is still the plan to use on a gaming PC.
Is Xbox mode the same as Game Mode?
No. Xbox mode is Microsoft’s console-style full screen gaming experience for Windows 11 version 24H2 and later, switched on under Settings > Gaming > Xbox mode. Game Mode is the background-priority switch on its own page under Settings > Gaming > Game Mode. They are separate settings.
Do I need Xbox Game Bar for Game Mode to work on a Ryzen X3D?
On a dual-die chip, keep it installed and updated. Tom’s Hardware’s 7950X3D review lists four requirements for AMD’s thread placement, a new chipset driver, an updated BIOS, Windows Game Mode and an updated Xbox Game Bar, and describes Game Bar as the piece that detects a game from its known-good list and triggers Game Mode. Single-die chips such as the 7800X3D and 9800X3D have no second die to park.
