Games stutter or have uneven frame times on Windows 11: how to fix it

Published Sources checked By helps.wiki editorial team

Stutter means frames arrive unevenly, so a game can feel choppy even when the FPS counter looks fine. Windows 11 has no error code for it, and the cause varies by setup. Start with driver and Windows updates, close background apps, then test HAGS and Memory Integrity one at a time.

What it means

Stutter is uneven frame delivery: short hitches, micro-freezes or spikes in frame time. It is different from low FPS. A game can report 90 FPS on average and still feel rough if a few frames take far longer than the rest.

There is no single fix, because there is no single cause. Windows 11 shows no error for it. The steps below go from the quickest and safest to the one that reduces protection, so work through them in order and change only one thing at a time. That way you will know what actually helped. This page covers frame-time stutter only, not a low average FPS or network lag.

Symptoms and causes

You are likely dealing with this problem if:

  • Periodic hitches or short freezes during play
  • Frame-time spikes, or a smooth FPS counter but a choppy feel
  • Stutter while moving the mouse, especially with a high-polling-rate mouse
  • Freezes when system RAM is nearly full

The usual causes, most common first:

Virtualization-based security and Memory Integrity
Memory Integrity is part of virtualization-based security (VBS). Microsoft states that older CPUs (Intel before Kaby Lake, AMD before Zen 2) rely on emulation and see a bigger performance impact. How much it affects games is only quoted in secondary sources, with widely different figures.
Hardware-Accelerated GPU Scheduling (HAGS)
Microsoft makes no specific performance claim for it, and the effect depends on the GPU and driver. It may help, hurt or change nothing.
High-polling-rate mouse on older builds
On older Windows 11 builds a high-polling-rate mouse could overload the input stack. The July 2023 update KB5028185 reportedly reduced that load (reported by a secondary source).
Shader compilation
Some games stutter while compiling shaders. That is the game's behaviour, not a Windows fault.
Other system load
Drivers, background programs, memory use, heat and storage are often suggested in community guides, but I found no Microsoft documentation tying them to stutter, so the steps below treat them as things to rule out, not as proven causes.

How to fix it

Work through these in order. They start with the quickest, safest checks and move to deeper repairs; stop as soon as the problem is gone.

1.Update drivers and Windows

Easy

Running current drivers and the latest cumulative update removes outdated software as a variable. The latest cumulative update also includes the KB5028185 mouse-input fix.

  1. Download the latest graphics driver from the NVIDIA, AMD or Intel website for your card and install it.
  2. Open Settings > Windows Update, click Check for updates and install everything offered, then restart.
  3. Install the latest chipset driver from your motherboard or laptop maker (or from AMD or Intel), then test the game again.

2.Close background apps and test again

Easy

If the stutter disappears with everything else closed, something running in the background is competing with the game.

  1. Close browsers, launchers you do not need, and any overlays.
  2. Press CtrlShiftEsc to open Task Manager and check on the Processes tab for anything using a lot of CPU, memory or disk while you play.
  3. Play for a few minutes and compare. Reopen apps one by one if the stutter is gone, to find the culprit.

3.Check RAM, temperatures and where the game is installed

Easy

This rules out resource limits on your particular PC. Community guides commonly suggest these checks, but how much they matter depends on your hardware.

  1. With the game running, watch memory use in Task Manager (Performance tab). If memory sits near full, close other programs or lower texture quality in the game.
  2. Check CPU and GPU temperatures with a monitoring tool or your laptop maker's software, and clean the vents if the machine is very hot.
  3. If the game is on a hard disk, try it on an SSD and keep some free space on that drive.

4.Look at Game Mode and the power mode

Easy

Some community guides suggest these two settings may affect smoothness. I could not confirm that against a Microsoft page, so treat this as an optional comparison, not a known fix.

  1. Open Settings > Gaming > Game Mode and see whether it is on. Menu names can differ between builds, and newer builds may show extra gaming options on this page.
  2. Open Settings > System > Power and try a higher performance power mode than the one currently set. Keep laptops plugged in. If nothing changes, put the setting back.

5.Test Hardware-Accelerated GPU Scheduling on and off

Easy

Microsoft makes no specific performance claim for HAGS, and results vary by GPU and driver, so the only way to know is to compare.

  1. Open Settings > System > Display > Graphics and look for Default graphics settings. The HAGS toggle only appears if your GPU and driver support it (it needs a WDDM 2.7 driver).
  2. Switch the toggle to the opposite state and restart the PC.
  3. Play the same scene as before. Keep whichever setting feels smoother.

6.Check whether virtualization-based security is running

Moderate

Before changing anything, confirm VBS is actually active on your PC. If it is off, it cannot be the cause.

  1. Press WinR, type msinfo32 and press Enter. On the System Summary page, read the Virtualization-based security line. Microsoft recommends running it from an elevated session.
  2. Alternatively, in an elevated PowerShell, run the command below. A VirtualizationBasedSecurityStatus of 2 means VBS is running.
    PowerShellrun as administrator
    Get-CimInstance -ClassName Win32_DeviceGuard -Namespace root\Microsoft\Windows\DeviceGuard

7.Turn Memory Integrity off briefly as a test

ModerateChanges settings

On older CPUs especially, VBS carries a larger performance cost. Turning Memory Integrity off shows whether it plays a part in your stutter, though the size of any benefit is only reported by secondary sources.

Before you start: Memory Integrity protects the kernel from malicious code. Turning it off lowers that protection, and Windows 11 22H2 and later shows a warning while it is off. If the switch is greyed out and says it is managed by your administrator, policy controls it and you should not work around it. Turn it back on after testing unless the difference is clear and you accept the trade-off.

  1. Open Windows Security > Device security > Core isolation details.
  2. Switch Memory integrity off, then restart the PC.
  3. Play the same scene. If nothing improves, go back to the same page, switch Memory integrity on and restart. If it will not turn back on, an incompatible driver may be the reason. Do not force it, and see Microsoft's Memory Integrity page for guidance.

Check that it worked

  • The frame-time graph in your monitoring overlay or tool stays flat in the scene that used to hitch.
  • The hitches no longer appear after 15 to 20 minutes of normal play, not just the first few minutes.
  • If you turned Memory Integrity off for testing, you have decided deliberately whether to leave it off or switched it back on.

If it still fails

  • If only one game stutters, especially in the first minutes in new areas, shader compilation is likely, so check that game's settings and its official support pages or forums.
  • Note which change helped or did nothing, and which setting you left changed. Then restore anything you only changed for a test.
  • If the stutter comes with crashes, very high temperatures or a failing drive, treat it as a hardware problem and contact the PC or component maker's support.
  • If you believe a specific Windows 11 build caused it, check Microsoft's Windows release health page for known issues on your version.

Questions

Why does my game stutter when the FPS counter looks fine?

The counter shows an average. Stutter is a few frames taking much longer than the others, which an average hides. A frame-time graph shows it.

Is there an error code for stuttering?

No. Windows 11 gives no error for it, so you have to narrow down the cause by changing one setting at a time.

Should I leave Memory Integrity off?

Only if testing shows a clear gain and you accept less kernel protection. It is a security feature, and the stutter benefit is reported by secondary sources, not measured here.
