Before you start a game, check five Windows graphics and latency settings: Game Mode, Hardware-accelerated GPU scheduling (HAGS), Optimizations for windowed games, Variable refresh rate (VRR), and the display’s highest suitable refresh rate. They are not five universal factory-disabled switches. Availability depends on your Windows version, GPU, driver, monitor, resolution and the game’s rendering path; Game Mode is already enabled by default for most Windows games.
The checklist below gives you the exact paths, eligibility rules and rollback advice. Enable only options your hardware exposes, and treat smoother frame delivery or lower latency—not guaranteed extra FPS—as the goal.
The five checks at a glance
| Setting | Where to check | Who can use it | What it can change |
|---|---|---|---|
| Game Mode | Settings > Gaming > Game Mode | Most current Windows gaming systems; the UI and default can vary by edition | Prioritizes game-related activity when other workloads compete |
| HAGS | Settings > System > Display > Graphics > Change default graphics settings | Only systems with a supported GPU and driver | Moves most GPU scheduling work to dedicated scheduling hardware |
| Optimizations for windowed games | Settings > System > Display > Graphics > Default settings (Windows 11) | Compatible DirectX 10/11 games in windowed or borderless mode | Uses flip-model presentation to reduce frame latency |
| Variable refresh rate | Settings > System > Display > Graphics > Default settings | A VRR-capable display plus the required drivers | Matches display refresh timing to supported game frame delivery |
| Highest suitable refresh rate | Settings > System > Display > Advanced display, or your GPU control panel | Only refresh modes your display and chosen resolution support | Higher refresh can reduce scanout latency |
Windows can also apply graphics preferences per application. An individual game’s profile may override a global choice, and some switches affect only particular APIs or presentation modes. Check the game’s own display settings after changing Windows options.

Open Settings > Gaming > Game Mode and turn the switch on if it is available and off. Game Mode tells Windows to favor game-related processes when background activity competes for CPU, disk or other resources. NVIDIA includes it among its latency recommendations in its system-latency guide.

Do not assume your PC shipped with this disabled. Microsoft’s Game Mode API reference says most Windows games receive Game Mode behavior by default without user opt-in. That reference is marked deprecated, and Windows editions do not necessarily expose identical controls, so the practical action is to verify the current switch rather than infer its state.
When it helps
Game Mode matters most when a game shares the machine with downloads, updates, browser tabs, recording software or other sustained workloads. With little competing activity, changing it may have no visible effect. It is a scheduling preference, not an FPS boost guarantee.
If a game behaves worse
Turn Game Mode off temporarily and relaunch the game. If the problem disappears, leave it off for that title and reduce the competing background workload instead. Record the game, Windows build and driver version so you can reproduce the comparison after an update.
2. Hardware-accelerated GPU scheduling (HAGS): use it only when offered
In Windows, go to Settings > System > Display > Graphics > Change default graphics settings. If Hardware-accelerated GPU scheduling appears, your GPU and installed driver meet Windows’ basic eligibility requirements. Switch it on, select Save if shown, then restart Windows before judging a game.
Rank #2

- AMD FreeSync reduces choppiness, screen lag and image tearing, ensuring that your fast-paced, complex in-game action is stable with minimal stutter
- Ergonomic stand allows for tilt, pivot and height adjustments to maximize gaming comfort
HAGS moves most GPU scheduling work from the CPU to dedicated scheduling hardware on the GPU. Microsoft introduced it as an opt-in feature because validation could not cover the full range of PC configurations. The engineering goal, described by Microsoft DirectX lead Steve Pronovost in the Hardware Accelerated GPU Scheduling article, was to modernize a core graphics subsystem and prepare for future changes—not to promise a measured gaming gain.
Eligibility and expectations
- No switch means the current GPU, driver or Windows build does not support HAGS; there is nothing to force.
- A visible switch confirms compatibility, not a guaranteed frame-rate increase.
- Different driver versions and games can respond differently, so assess frame-time consistency, input feel and stability rather than looking only at an average FPS counter.
How to test and roll back
- Close games and GPU-heavy applications.
- Enable HAGS and restart Windows.
- Play the same area or benchmark sequence for several minutes with the same resolution, upscaling and frame cap.
- If you see crashes, stutter, capture problems or a worse workload, return to the same Graphics page, disable HAGS and restart again.
Keep the setting that is more stable for your particular games. Microsoft’s discussion does not establish a universal performance result, so do not leave HAGS enabled solely because the label sounds faster.
3. Optimizations for windowed games: a Windows 11 presentation setting
On Windows 11, open Settings > System > Display > Graphics > Default settings and look for Optimizations for windowed games. Microsoft documents the feature in its Windows 11 support article.
The option targets DirectX 10 and DirectX 11 games running in a window or borderless window. For eligible titles, Windows can use a flip-model presentation path instead of the older blit path. That can reduce the time a rendered frame waits before appearing and makes modern display features work more consistently in windowed play.
Rank #3
- Smooth motion: 240Hz refresh rate and fast 0.5ms response time provide crisp visuals and fluid movement with less input lag.
- Seamless gaming: FreeSync Premium and HDMI VRR eliminate tearing for smooth, responsive PC and console gameplay.
- Fast IPS: Faster 0.5ms response with excellent color accuracy across wide IPS viewing angles.
- Rich color: 99% sRGB color coverage delivers vivid, detailed imagery with strong accuracy.
- Eye comfort: TÜV Rheinland 3‑star certified display lowers blue light while preserving color quality.
Exact procedure
- Open the Graphics page and switch on Optimizations for windowed games.
- Restart every affected game. The change is not reliably applied to a title that was already running.
- In the game, select windowed or borderless mode and confirm that the title is using DirectX 10 or 11 if it offers an API selector.
- Test input response and frame pacing in the same scene you normally play.
Auto HDR changes the interaction: enabling Auto HDR automatically turns on Optimizations for windowed games. If you disable Auto HDR later, check the optimization switch again instead of assuming the previous state remains.
What it does not cover
- DirectX 12 and Vulkan titles are not the target described by Microsoft’s feature documentation.
- A game running in exclusive fullscreen follows a different presentation path.
- The switch cannot make an incompatible game use flip-model presentation or create HDR capability where the display lacks it.
4. Variable refresh rate (VRR): check the monitor before the switch
In Settings > System > Display > Graphics > Default settings, look for the Windows variable-refresh-rate option. Enable it only when the PC has the necessary graphics drivers and the connected monitor or television supports a VRR standard. Microsoft lists AMD FreeSync, NVIDIA G-SYNC and VESA Adaptive-Sync as examples in its redesigned Graphics settings guidance.
VRR lets a compatible display vary its refresh timing to follow frame delivery, reducing visible tearing and uneven cadence when frame rate fluctuates. Windows’ option is specifically useful for eligible DirectX 11 fullscreen games that do not implement VRR support themselves. It cannot add VRR to a fixed-refresh panel, and a cable, port, firmware or driver limitation can prevent the monitor from advertising the capability.
Verify the complete signal path
- Check the monitor’s on-screen display for its Adaptive-Sync, FreeSync or G-SYNC setting and enable it if required.
- Use a port and cable rated for the resolution and refresh mode you selected.
- Install the current graphics driver offered for your GPU, then revisit Windows Graphics settings.
- Check the game’s own fullscreen and V-Sync options; per-game settings can override system preferences.
VRR has a usable operating range. If a game’s frame rate falls below or rises above that range, the driver or display may use frame doubling, a cap or V-Sync behavior. Set a frame cap inside the range when the game or driver provides one, and verify the result with the display’s indicator or an in-game diagnostic rather than assuming the Windows switch alone proves VRR is active.

5. Maximum suitable refresh rate: choose the mode your display actually supports
Open Settings > System > Display > Advanced display, select the correct monitor and choose the highest refresh rate listed for your current resolution. You can also make this choice in the GPU control panel. NVIDIA explains in its latency guide that a higher refresh rate reduces scanout latency: the display spends less time drawing each frame.
“Highest” means the highest suitable mode, not an unsafe or inconvenient one. A display may offer 165 Hz at a lower resolution but only 144 Hz at its native resolution, or a high mode only through a particular port. Pick the mode the monitor documents for the resolution, color depth and connection you use. Windows cannot create a refresh rate that the panel and link do not support.
Confirm it in the game
- Set the Windows refresh rate first.
- Open the game’s video menu and select the same resolution and refresh rate when the game exposes separate values.
- Disable any accidental 60 Hz cap, or set an intentional frame cap suited to your VRR range.
- Watch for black screens, signal dropouts or flicker. If they occur, return to Advanced display and select the last stable mode.
Refresh rate affects latency and motion clarity; it does not guarantee that the GPU can render at that frame rate. A 240 Hz mode still displays a game at 90 frames per second unless the game and GPU produce more frames.
A game-specific latency option: NVIDIA Reflex
NVIDIA Reflex is not a sixth universal Windows switch. In a supported game, look in the game’s graphics or latency menu and enable Reflex if the option exists. NVIDIA recommends it because the game can coordinate CPU and GPU work to reduce render-queue delay. Support, naming and available modes vary by title and GPU, so follow the game’s documentation and compare input response with the same frame cap and display mode.

Per-game overrides and a safe testing order
Windows Graphics settings can contain app-specific profiles. If a title has its own entry, open it and inspect the selected GPU, power preference and any feature-specific options before assuming the global default applies. A launcher, driver profile or game patch can also change presentation behavior.
- Update Windows and the graphics driver through the normal supported channels, then reboot.
- Set the display to its documented stable refresh mode.
- Verify Game Mode.
- Enable windowed-game optimizations if you use an eligible Windows 11 DirectX 10/11 title.
- Enable VRR only after confirming the monitor, port and driver support it.
- Test HAGS last, because it changes a lower-level scheduling path and may affect stability differently across workloads.
- Change one setting at a time and keep notes on the game, resolution, frame cap, driver and symptoms.
Use a repeatable save file or built-in benchmark. Compare frame-time smoothness, input delay and crashes over the same sequence; do not treat a single FPS reading as proof that a switch helped.
Troubleshooting when a setting is missing or causes problems
The option is not listed
Missing HAGS usually means unsupported hardware, driver or Windows build. Missing VRR means the display or driver has not exposed a compatible path. Windowed-game optimizations require Windows 11 and an eligible presentation path. Install the correct driver, reconnect the monitor directly, check the Windows edition and confirm the game mode before concluding that a setting is hidden.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
The game stutters after a change
Undo the last change, restart the game and then restart Windows if the change involved HAGS. Check for a per-game profile, overlays, recording software and background downloads. Keep the option disabled if the same reproducible workload remains worse; there is no benefit in forcing a feature that is unstable on your system.
The screen tears or feels uneven
Confirm that VRR is enabled both in the display’s own menu and in the appropriate driver or Windows path. Recheck the selected refresh mode and use a frame cap inside the display’s VRR range when available. If the monitor never supports VRR, the Windows toggle cannot remedy tearing; use a supported synchronization option in the game or driver instead.
What “hidden” really means here
These controls are easy to overlook because they sit in separate Windows pages, appear only on eligible hardware, or are superseded by per-game profiles. They are not evidence that every PC manufacturer deliberately disables the same five performance features. Microsoft’s documentation describes conditional availability and default behavior, while NVIDIA’s recommendations describe ways to reduce latency rather than promises of a universal FPS increase.
Use the checklist as a compatibility audit: verify Game Mode, select a stable high refresh mode, enable VRR and windowed optimizations when your display and game qualify, and experiment with HAGS only when Windows offers it. The result should be a system whose display timing and scheduling choices match the hardware you actually own.
