Lag turns games and apps into choppy video, delayed controls, frozen screens, slow browser sessions, and online matches that jump around. Start by clearing local bottlenecks, then move through updates, graphics settings, storage, browser controls, network checks, console settings, and deeper repairs. Use the path that matches your device first, then test the same game or app again before moving on.
1. Clear the fastest bottlenecks first
Close games, apps, and browser tabs you are not using.
On Windows 11, press Ctrl + Shift + Esc, open Task Manager, choose Processes, then close apps you are not using.
Restart Windows from Start > Power > Restart, then reopen only the game or app you need.
On Mac, quit unused apps, then open Activity Monitor and check memory and app usage.
On iPhone or iPad, force-close an app only when it is not responding: open the app switcher, find the app, then swipe up on its preview.
On Pixel phones, open Settings > Apps > See all apps, choose the lagging app, tap Force stop, then tap OK. Google notes these settings vary by phone, so on other Android devices open your manufacturer's app settings screen and force stop the app there.
2. Enable Windows Game Mode
For Windows 11 PC games, use Start > Settings > Gaming > Game Mode, then turn Game Mode on. Windows 10 has the same setting, but Windows 10 consumer support ended on October 14, 2025, so use the Windows 11 path for current consumer troubleshooting.
3. Update the system, apps, and drivers
On Windows 11, open Start > Settings > Windows Update, then choose Check for updates.
For optional Windows drivers, open Start > Settings > Windows Update > Advanced options > Optional updates, select the updates, then choose Download & install.
For NVIDIA GeForce PCs, use NVIDIA's official drivers page to download a Game Ready Driver, or open NVIDIA App > Drivers and install the available update.
For AMD systems, use AMD's official Drivers and Support page, run auto-detect or select your product, then install the official package.
For Intel hardware, download and run Intel Driver & Support Assistant, launch the utility, then apply detected Intel driver and software updates.
On iPhone or iPad, open App Store > My Account > App Updates, then choose Update next to the app or Update All.
On Android, open Google Play Store > profile icon > Manage apps & devices, then update all apps or the specific app.
On Mac, update macOS from System Settings > General > Software Update, then update App Store apps from App Store > Updates.
Restart after system, app, or graphics updates, then test the same scene or task again.
4. Shift graphics performance to the game
On Windows 11 PCs that show Power mode, open Start > Settings > System > Power & battery > Power mode, then choose Best performance.
For a specific Windows game or app, open Start > Settings > System > Display > Graphics, select the app under Custom options for apps, choose Options > Graphics preference > High performance > Save, then restart the game or app.
For DirectX 10 and DirectX 11 games running windowed or borderless windowed, open Start > Settings > System > Display > Graphics > Default settings, turn Optimizations for windowed games on, then restart the game.
For a demanding Windows game, open Start > Settings > System > Display > Display resolution, choose a lower supported resolution, then restart the game when prompted.
On supported Windows 11 Copilot+ PCs, open Start > Settings > System > Display > Graphics > Custom settings for applications, find the game or add its .exe file, then set the Automatic super resolution toggle to On. Auto SR needs a Copilot+ PC with a Snapdragon X or X2 Series processor (or a ROG Xbox Ally X), Windows 11 version 24H2 or later, a 1080p or higher display, current graphics and neural processor drivers, and a DirectX 10 or later game.
In a supported NVIDIA Reflex game, open the game's graphics or video options, then enable NVIDIA Reflex or Reflex Low-Latency.
On supported AMD Radeon systems, open AMD Software: Adrenalin Edition > Home > HYPR-RX profiles, then choose HYPR-RX.
On supported AMD Radeon systems that expose the option separately, enable Radeon Anti-Lag in the graphics or game settings.
5. Free storage and cut background load
This fixes lag caused by low free space, startup apps, background app activity, and visual effects using resources.
On Windows 11, run cleanup from Start > Settings > System > Storage > Storage Sense > Run Storage Sense now.
For manual Windows cleanup, open Start > Settings > System > Storage > Temporary files, select files, then choose Remove files.
Remove unused Windows apps from Start > Settings > Apps > Installed apps, choose the app's More options button, then select Uninstall.
Stop startup apps in Windows from Ctrl + Shift + Esc > Task Manager > Startup apps, right-click the app, then choose Disable.
For Windows Store apps that show the control, open Start > Settings > Apps > Installed apps, open the app's More options > Advanced options > Background app permissions, then set Let this app run in the background to Never.
Reduce Windows visual effects by opening Start, typing Adjust the appearance and performance of Windows, opening that result, choosing Visual Effects, then selecting Adjust for best performance.
On iPhone or iPad, open Settings > General > Device Storage, review recommendations, or tap an app and choose Offload App or Delete App. Keep at least 1 GB free.
On Android, free space from Settings > Storage > Free up space, choose a category, choose Select files, select files, then tap Move files to Trash.
On Mac, open Apple menu > System Settings > General > Storage, then use the storage recommendations.
6. Tune Chrome and Edge for web games
In Chrome, turn on Memory Saver from More > Settings > Performance > Memory Saver, then choose Moderate, Balanced, or Maximum.
Keep a Chrome browser game active by opening More > Settings > Performance > Always keep these sites active > Add, then add the current site or enter the web address and choose Add.
Turn off Chrome Energy Saver for gaming from More > Settings > Performance > Energy Saver > Off.
In Microsoft Edge, turn on sleeping tabs from Settings and more > Settings > System and performance > Performance > Automatically put tabs to sleep, then choose when inactive tabs sleep.
Keep an Edge browser game active from Settings and more > Settings > System and performance > Performance > Always keep these sites active > Add site, enter the full URL, then choose Add.
Turn off Edge Energy saver from Settings and more > Settings > System and performance > Performance > Enable energy saver > Off.
When Edge flags a heavy tab, open Settings and more > More tools > Performance, select the 3 dots next to that tab, then choose Sleep tab or Close tab.
For a lagging Windows process running in Efficiency mode, open Start > Task Manager > Processes, expand the process group when needed, right-click the process, then choose Efficiency mode to turn it off.
7. Separate online lag from FPS lag
Check the official service status first: use the PlayStation Service Status page for PlayStation, the Xbox Status page for Xbox, and Steam's troubleshooting guidance for Steam games.
Use Ethernet for Windows PCs, consoles, and streaming devices with Ethernet support.
On Windows 11, open the Get Help app, search connect to network and internet, choose Run network diagnostics, then complete the steps shown.
On Xbox, open Settings > General > Network settings, then run Test network speed & statistics or Test multiplayer connection and review latency and packet loss.
For Steam download or content-server lag, open Steam > Settings > Downloads > Download Region, choose another region, then retry the download.
For Steam Remote Play, open Steam > Settings > Remote Play > Advanced Host Options, then check Prioritize Network Traffic.
For Xbox Cloud Gaming in the Xbox app on Windows, open Xbox app > profile pic > Settings > Cloud Gaming, then turn on the Network quality indicator.
When frame rate looks smooth but inputs or online players jump, fix the network path before lowering graphics settings.
8. Switch console performance options
On PS5, choose the performance preset from Settings > Saved Data and Game/App Settings > Game Presets > Performance Mode or Resolution Mode > Performance Mode; it applies to games that offer performance and resolution modes.
For display stutter on a compatible TV or monitor, use Settings > Screen and Video > Video Output to adjust Resolution, VRR, 120 Hz Output, or ALLM.
On Xbox Series X|S, open a supported backward-compatible game's compatibility options and enable FPS boost.
9. Use deeper repairs last
Run a Windows malware scan from Start > Settings > Privacy & security > Windows Security > Virus & threat protection > Quick scan.
On iPhone 15 and later, open Settings > Battery > Power Mode, then turn Low Power Mode off.
On iPhone 14 and earlier, open Settings > Battery > Low Power Mode, then turn Low Power Mode off.
Move an iPhone or iPad to a moderate-temperature environment when it is too hot or too cold, then resume the game or app.
Check persistent iPhone performance problems from Settings > Battery > Battery Health on iPhone 15 and later, or Settings > Battery > Battery Health & Charging on iPhone 14 and earlier. If Service appears next to the battery health reading, consider replacing the battery.
On Mac, force-quit a frozen app with Option + Command + Esc, select the app, then choose Force Quit.
If a Mac will not restart normally, press and hold the power button for up to 10 seconds until it turns off, then press and release the power button to turn it back on.
On supported Mac models, open Apple menu > System Settings > Battery, or Energy on desktops, then set Energy Mode to High Power Mode.
On Pixel phones, clear a problem app's cache from Settings > Apps > See all apps, choose the app, open Storage & cache, then tap Clear cache. Use Clear storage only when you are ready to delete that app's data. Google notes these settings vary by phone, so use your manufacturer's app storage screen if the labels differ.
Use Android Safe Mode to identify a recently downloaded problem app: restart in Safe Mode, check whether lag goes away, restart normally, remove recently downloaded apps one by one, then restart normally after each removal.
On PlayStation, turn off the console, hold the power button until the second beep, then choose Clear Cache and Rebuild Database on PS5, or Rebuild Database on PS4.
Delete and redownload a PlayStation game when launch or play issues continue, and use a wired connection during the redownload.
Frequently Asked Questions
Why does my game lag even when my internet is fast?
Local performance problems still cause lag on a fast connection. Close unused apps, update graphics drivers, turn on Windows Game Mode, and set the game to the high performance GPU before treating it as a network issue.
Should I clear app cache to fix lag?
On Android, clearing cache helps a slow or misbehaving app. Clear storage deletes that app's data, so use it only when you are ready to lose local app data.
Does lowering resolution really help game lag?
Yes. On Windows 11, lowering display resolution before launching a demanding game reduces the GPU workload for supported display modes.
What should I do if only online games lag?
Check the platform service status first, use Ethernet, and run the platform's network tests. On Xbox, review latency and packet loss; on Windows, run network diagnostics from the Get Help app.
Does Edge Gamer Mode still fix lag?
No. Microsoft marks the Edge Gamer Mode policy obsolete and non-working after Edge version 140, so use Edge System and performance settings instead.
