How to Fix Game Stuttering on PC: The Complete Checklist

Yes, you can fix most game stuttering on a PC, usually without new hardware. In almost every case the cause is one of eight things: an uncapped frame rate, heat, a bad graphics driver, shader compilation, slow RAM settings, slow storage, background apps, or one wrong Windows setting.

Every fix here follows the official documentation and support pages of Microsoft, NVIDIA, AMD, and the tool makers. We ordered them so the fix that helps the most PCs comes first.

In this guide, we will show you how to measure stuttering, match your symptom to its cause, and apply each fix with exact steps for both brands.

What You Need Before You Start

Three free tools, and 45 to 60 minutes if you do every fix.

• A frame time tool: Intel PresentMon, CapFrameX, or MSI Afterburner with RTSS.
• A temperature tool: HWiNFO, or the Afterburner overlay. Used in Fix 2.
• DDU (Display Driver Uninstaller): Only needed if you reach Fix 3.
• Your driver installer: Download it now from the official NVIDIA or AMD site, in case you go offline.

One safety habit: change one thing at a time, and test after each fix.

What Is Frame Time, and Why It Matters More Than FPS

Your FPS counter shows an average, and an average hides the problem. Your screen shows a stream of still pictures called frames. At a smooth 60 FPS, your PC finishes one frame every 16.7 milliseconds. That gap between frames is the frame time.

Think of frames like cars leaving a factory gate. One car every second and traffic flows. Ten cars at once, then nothing for ten seconds, and traffic feels broken, even though the same number of cars left. A stutter is one frame that takes 100 milliseconds while its neighbours take 16.

Step 0: Measure Before You Change Anything

Time needed: about 10 minutes.

Do not guess. First, turn on a frame time graph. It draws stutter as spikes, and the spike pattern tells you which fix to try.

Option 1: MSI Afterburner with RTSS

1. Install MSI Afterburner. RTSS installs with it. Tick its box during setup if asked.
2. Open Afterburner. Click the Settings gear icon.
3. Click the Monitoring tab.
4. Click Frametime in the list. Tick Show in On-Screen Display.
5. Click OK and start your game. The graph draws while you play.

Option 2: Intel PresentMon or CapFrameX

PresentMon is free and works on all three brands. Its GPU Busy reading shows whether the card is doing real work or waiting on something else. CapFrameX does the same job and saves results for comparisons.

Play for five minutes and read the spikes

Fading spikes mean shader compilation (Fix 4). Spikes on fast turns and new areas mean slow storage (Fix 6). Spikes that worsen as you play mean heat or VRAM (Fix 2). Spikes in every game mean a driver or Windows problem (Fix 3, Fix 7, Fix 8).

Find Your Cause: The Symptom Table

Match what you see to a row, then jump to that fix. No match? Work through Fix 1 to Fix 8 in order.

Fix 1: Set a Frame Cap and Fix Your Sync Setup

Time needed: about 5 minutes. Do this fix first, even if the table pointed elsewhere.

The refresh rate is how many new pictures your screen draws per second: a 144 Hz monitor draws 144. G-Sync (NVIDIA) and FreeSync (AMD) are sync systems: the monitor waits for each finished frame instead of showing a half finished one. Without a cap, frame rate bounces above and below the refresh rate, and with V-Sync on in the game that bouncing becomes judder. The cure is a cap just below the refresh rate.

Step 1: Check your monitor runs at full speed

1. Right click an empty part of the desktop. Click Display settings.
2. Scroll down and click Advanced display.
3. Find Choose a refresh rate. If it says 60 Hz and your monitor supports more, pick the highest number, for example 144 Hz.

Stuck on 60 Hz? Do not worry. Windows resets it after driver updates.

Step 2 (NVIDIA): Turn on G-Sync

1. Right click the desktop. Click NVIDIA Control Panel.
2. Under Display in the left panel, click Set up G-SYNC.
3. Tick Enable G-SYNC, G-SYNC Compatible.
4. Choose Enable for windowed and full screen mode and click Apply.

Step 2 (AMD): Turn on FreeSync

1. Right click the desktop. Click AMD Software: Adrenalin Edition.
2. Click the Display tab.
3. Switch AMD FreeSync to On.

Step 3: Turn V-Sync off inside the game

Open the game’s graphics settings. Find V-Sync (some games call it Vertical Sync) and set it to Off. Sync does the job better now.

Step 4 (NVIDIA): Set the frame cap

1. Open the NVIDIA App. Click Graphics.
2. Click Program Settings and pick your game.
3. Find Max Frame Rate. Switch it On. Type 141 on 144 Hz, or 237 on 240 Hz.
4. Click Apply.

The rule is refresh rate minus 3: 162 on 165 Hz, 57 on 60 Hz. If the game has its own limiter, use that instead. One cap only, never two.

Step 4 (AMD): Set the frame cap

1. Open AMD Software. Click the Gaming tab and pick your game. To cap every game at once, click the Settings gear, then Graphics instead.
2. Turn on Radeon Chill.
3. Set Min FPS and Max FPS to the same number: 141 on 144 Hz, or 237 on 240 Hz. Equal numbers turn Chill into a fixed cap.
4. Some cards on current drivers also list Frame Rate Target Control under Global Graphics, in the Advanced section. It sets the same cap with one slider. Use one method only. Never run two caps at once.

Fix 2: Rule Out Heat

Time needed: about 10 minutes, plus cleaning time if heat is your cause.

Stutter that starts on a schedule is heat until proven otherwise. Every chip has a temperature limit. At the limit, the chip protects itself by slowing down. That slowdown is thermal throttling, and each one is a spike on your graph. Then it speeds up, heats up, and slows down again.

Check temperatures while you play

1. Open HWiNFO, or the Afterburner overlay from Step 0.
2. Show two readings: GPU temperature (core) and GPU hotspot temperature (hottest point).
3. Play at least 15 minutes. The desktop tells you nothing.
4. Read the numbers as the stutter happens.

Healthy for a desktop card under load: a core at 65 to 80 degrees C. A hotspot near 105 to 110 degrees C means throttling is likely.

If heat is your cause, fix the cooling

1. Shut the PC down and switch the power supply off.
2. Blow dust from the card’s fins and case fans with compressed air. Hold each fan blade still with a finger.
3. Check airflow: one fan in at the front, one out at the back, and space around the case.
4. Keep the Fix 1 frame cap. A cap is also a cooling fix.

Fix 3: Clean Install Your Graphics Driver With DDU

Time needed: about 20 to 30 minutes. Do this if stutter started after a driver update, or appears in every game.

A driver is the software that lets Windows talk to your graphics card. A normal update installs over the old one, and sometimes leaves a stuttering mix of files. DDU (Display Driver Uninstaller) is a free tool that removes the driver completely. A normal uninstall is like moving out of a house but leaving boxes in the attic. DDU empties the whole house.

Step 1: Download everything first

1. On the official NVIDIA or AMD website, download the newest driver for your exact card model. Save it in Downloads.
2. Download DDU from Wagnardsoft or Guru3D, and unzip it.

Step 2: Disconnect from the internet

Unplug the network cable or turn Wi-Fi off, so Windows Update cannot install its own older driver mid process.

Step 3: Boot into Safe Mode

Safe Mode is a bare bones Windows that loads almost nothing, so no part of the old driver runs and locks files.

1. Open Settings, then System, then Recovery.
2. Under Advanced startup, click Restart now.
3. On the blue menu, click Troubleshoot, then Advanced options, then Startup Settings, then Restart.
4. When the list appears, press 4 for Safe Mode.

Do not worry if Windows looks huge and low resolution here. That is right.

Step 4: Run DDU

1. Open the DDU folder. Double click Display Driver Uninstaller.exe. If Windows warns you, click More info, then Run anyway.
2. Set the device type dropdown to GPU.
3. Set the brand dropdown to NVIDIA, AMD, or Intel.
4. Click Clean and restart (Highly recommended).
5. Wait. The screen may stay black for up to two minutes. Do not press the power button. The PC restarts by itself.

Step 5: Install the fresh driver

1. Stay offline. Run the saved installer and follow it to the end with its normal options.
2. Restart the PC when it finishes, even if it does not ask.
3. Reconnect your cable or Wi-Fi.
4. Redo Fix 1, Step 1: check your refresh rate. Driver installs often reset it to 60 Hz, which feels like stutter by itself.

Fix 4: Fix Shader Compilation Stutter

Time needed: about 5 minutes, plus play time while a fresh cache builds.

A shader is a small program that tells your card how to draw one effect, like fire or water. Your card cannot read shaders as the game ships them. They must be translated into the card’s own language first. That translation is compilation.

Think of a recipe book in another language. First time you cook a dish, you stop and translate line by line, and dinner is late. After that you keep the translation in a notebook, and the dish is fast forever. The shader cache is that notebook. Compile during play and you hitch the first time each effect appears, never the second. You cannot remove it completely, only shrink it.

NVIDIA: Make the cache bigger

1. Right click the desktop. Click NVIDIA Control Panel.
2. Click Manage 3D settings. Stay on the Global Settings tab.
3. Find Shader Cache Size. Open its dropdown and choose 10 GB.
4. Click Apply.

The default throws translations away too early in shader heavy games, so the card re translates the same recipes.

AMD: Reset a damaged cache

1. Open AMD Software. Click the Settings gear.
2. Click the Graphics tab. Open Advanced.
3. Find Reset Shader Cache. Click Perform Reset.

Only reset if stutter began after a driver change. A damaged notebook is worse than an empty one. After a reset, expect some hitches in the first session while it refills. That is normal.

Both brands: Let the game finish compiling

If a game shows a “compiling shaders” progress bar at launch or in its menu, let it finish, every time. Two patient minutes saves an evening of hitches. Caches belong to one driver version, so the first session after an update can hitch while the notebook refills.

Fix 5: Set Up Your RAM Correctly

Time needed: about 10 minutes, including one trip into the BIOS.

RAM problems cause small hitches in big open world games. Three checks, all free.

Check 1: Turn on XMP or EXPO

Your kit’s rated speed is on its box, for example 3200 or 6000. Out of the box, it does not run at that speed. It runs at a slow default until you switch the rated speed on. The switch is a saved profile, XMP on Intel and EXPO on AMD: the manufacturer’s own tested settings card.

1. Restart the PC and tap Del until the BIOS appears. Some PCs use F2. If Windows starts, restart and tap earlier.
2. ASUS: Press F7 for Advanced Mode, open Ai Tweaker, set Ai Overclock Tuner to XMP I (Intel) or EXPO I (AMD).
3. MSI: Open the OC page. Set Extreme Memory Profile (XMP) or the EXPO profile to Enabled or Profile 1.
4. Gigabyte: Open the Tweaker tab. Set Extreme Memory Profile (X.M.P.) or EXPO to Profile 1.
5. Press F10 and confirm Save and Exit.

Wording differs a little by brand. The setting is always named XMP, DOCP, or EXPO.

Check 2: Two sticks, right slots, dual channel

Your CPU reads RAM through paths called channels. One stick is one path. Two sticks are two paths side by side: dual channel, like a two lane road beside a one lane road. One stick quietly causes open world stutter. The CPU waits on its single lane.

1. PC off, check your sticks. Two sticks belong in the slots your manual marks for a pair, usually slots A2 and B2: second and fourth from the CPU.
2. Sticks side by side in slots one and two? Move the second stick to slot four.
3. Push each stick in until both end clips click shut.

Check 3: Enough RAM?

1. Play until it stutters, then press Ctrl + Shift + Esc.
2. Click Performance, then Memory.
3. If the game, Windows, and your apps use more than you have, Windows swaps data to the drive mid game. Those are hard hitches.

16 GB is the practical floor for modern games: two sticks, dual channel, profile on. One 16 GB stick at default speed can stutter more than a proper two stick kit.

Fix 6: Move the Game to Fast Storage

Time needed: 5 minutes to start. The move itself can take a while on a big game.

Modern open world games load their world in pieces as you move: streaming. A mechanical hard drive (HDD) has a spinning disk and a moving arm. It cannot deliver pieces fast enough. The game pauses, and you feel a freeze. An SSD has no moving parts and delivers in time.

Move the game to an SSD (Steam)

1. Open Steam. Click Steam (top left), then Settings.
2. Click Storage and pick the drive the game lives on now.
3. Tick the box next to the game, click Move, choose your SSD, and confirm.

The Xbox app offers the same move under Manage on each game’s page.

Keep free space on the game drive

Keep 15 to 20 percent of the game drive empty. A drive over 90 percent full slows down, and Windows needs room there for caches and updates.

Watch VRAM while you are here

VRAM is the memory on your graphics card itself. If the graph worsens over a session and VRAM sits at 95 to 100 percent, the card swaps data with normal RAM. It looks exactly like a storage problem. Ten second fix: drop Texture Quality one notch, for example Ultra to High.

Fix 7: Close Background Apps, Overlays and Captures

Time needed: about 10 minutes.

The random hitch every minute comes from behind the game: a browser with forty tabs, a cloud drive syncing clips, a second launcher updating another game, RGB software polling sensors.

Step 1: Find the culprit live

1. Play until it hitches. Press Ctrl + Shift + Esc.
2. On the Processes tab, click the CPU column header to sort.
3. Close anything near the top that you do not need while gaming: browsers, sync tools, updaters.

Step 2: Turn background recording off

1. Open Settings, then Gaming, then Captures.
2. Switch off Record what happened. It quietly films your last minutes of play, always.
3. Press Win + G. In Game Bar Settings, untick Record in the background while I am playing a game if ticked.

Step 3: Run one overlay at most

Discord, Steam, NVIDIA, AMD, and Game Bar overlays all hook into the same frame pipeline. Stacked, they fight over every frame. In each app’s settings, turn the overlay switch off for all but one.

Step 4: Test fullscreen optimizations

1. Find the game’s .exe. In Steam: right click the game, Manage, Browse local files.
2. Right click the .exe. Click Properties, then the Compatibility tab.
3. Tick Disable fullscreen optimizations. Click Apply, then OK, and test.

The undo is built in: no change, untick the same box.

Step 5: Prune startup apps

1. Open Task Manager. Click the Startup apps tab.
2. Right click each launcher and updater you do not need at boot. Click Disable.

Fix 8: Change the Windows Settings That Matter

Time needed: about 10 minutes, plus restarts if you test both scheduling modes.

Dozens of gaming tweaks float around. Only a few do anything: these Microsoft ones.

Setting 1: Game Mode on

1. Open Settings, then Gaming, then Game Mode.
2. Switch Game Mode to On.

Setting 2: Test GPU scheduling both ways

Normally your CPU hands drawing jobs to the card, like a manager handing tasks to a worker. Hardware-accelerated GPU scheduling (HAGS) lets the card keep its job list instead. On most modern cards it is equal or slightly better. On some older cards and 8 GB cards, the old way can feel smoother. Test it.

1. Open Settings, then System, then Display, then Graphics.
2. Click Change default graphics settings.
3. Note how Hardware-accelerated GPU scheduling is set. Switch it the other way.
4. Restart the PC. The change does nothing until you restart.
5. Play the same section for ten minutes. Watch the graph. Test it set back, and keep the calmer result.

Setting 3: Power mode to Best performance

1. Open Settings, then System, then Power & battery.
2. Set Power mode to Best performance.
3. Desktop alternative: Control Panel, then Power Options, then High performance.

A power saving plan can park parts of your CPU mid game, and parked parts stutter.

Setting 4: Memory Integrity, read before you touch

Microsoft’s own gaming performance page names Memory Integrity and Virtual Machine Platform as features that can cost performance on some PCs. Turning security off is a decision, not a tweak. Only look here after every fix above. Read what Microsoft says first, and turn it back on if it does not help.

Common Mistakes That Make Stuttering Worse

• Changing five fixes at once. You will not know which one worked. One fix, one test.
• Driver booster and registry cleaner tools. They install wrong drivers and add background services. Drivers only from the official NVIDIA or AMD website.
• Capping above the refresh rate. 200 on a 144 Hz screen does nothing: frames still bounce against the sync window.
• Watching FPS instead of the frame time graph. Steady 60 FPS feels smoother than a bounce between 70 and 110. Judge by the graph.

When It Is the Game, Not Your PC

Some stutter ships with the game. Four signs:

• It started right after a patch. Check the game forum. If others report the same thing, wait for the hotfix.
• Same spots, same hitches, for everyone. The engine loads its world heavily. The Fix 1 cap often smooths it. Nothing removes it.
• Online only. Your graph stays clean while the world jumps. That is server or netcode, not your hardware.
• Every forum and outlet reports it. The cause is the game. The fix must come from the developer.

Frequently Asked Questions

The Bottom Line

Stutter has about eight common causes, and testing beats guessing. Measure the frame time. Match your symptom in the table. Work the fixes in order: cap and sync, heat, driver, shader cache, RAM, storage, background load, Windows settings. The graph confirms the fix.
