How to Fix Windows Memory Compression Causing Game Stutter

What Causes This?

Windows Memory Compression is designed to keep more data in RAM by compressing inactive memory instead of paging it to disk. During gaming, that can become a problem if your system is low on free RAM, too many background apps are running, or the page file is misconfigured. The result is extra CPU and memory overhead at the wrong time, which can cause stutter, frame-time spikes, and short freezes.

Common Symptoms

• Games stutter or hitch even when average FPS looks normal
• Short freezes happen when loading new areas, textures, or effects
• Task Manager shows high memory usage and noticeable CPU use from System
• Stutter gets worse with browsers, launchers, overlays, or recording apps open
• Performance improves temporarily after rebooting the PC

How to Fix It Manually

1. Check if RAM pressure is the real issue

   • Open Task Manager with Ctrl+Shift+Esc.
   • Click More details if needed, then open the Performance tab and select Memory.
   • If memory usage is consistently above 80–90% while gaming, memory compression is likely reacting to low available RAM rather than being the root problem by itself.

2. Close unnecessary background apps before launching your game

   • In Task Manager, open the Processes tab.
   • Sort by Memory to find heavy apps.
   • Close apps you do not need while gaming, especially:
     • Web browsers with many tabs
     • Game launchers you are not using
     • RGB/control software
     • Chat apps, overlays, and screen recorders
     • Virtual machines or creative apps left open in the background
   • Be careful not to end Windows system processes.

3. Disable unnecessary startup apps

   • In Task Manager, open the Startup apps tab.
   • Right-click apps you do not need at boot and choose Disable.
   • Focus on non-essential utilities, updaters, launchers, and tray apps that quietly consume RAM after startup.
   • Restart your PC after making changes.

4. Make sure your page file is enabled and managed correctly

   • Press Windows key, type View advanced system settings, and open it.
   • Under Performance, click Settings.
   • Go to the Advanced tab, then under Virtual memory, click Change.
   • Make sure Automatically manage paging file size for all drives is checked.
   • If it was disabled, enable it, click OK, and restart your PC.
   • A disabled or undersized page file can make RAM pressure and stutter worse.

5. Turn off Xbox Game Bar and other overlays if you do not use them

   • Open Settings > Gaming > Xbox Game Bar and turn it Off.
   • Then go to Settings > Gaming > Captures and disable background recording if enabled.
   • Also disable overlays in apps like Discord, GeForce Experience, Steam, or AMD Software if they are active during gameplay.

6. Update your graphics driver and Windows

   • Right-click Start and choose Settings.
   • Go to Windows Update and install all pending updates.
   • Then update your GPU driver from NVIDIA App/GeForce Experience, AMD Software: Adrenalin Edition, or Intel Driver & Support Assistant.
   • Outdated drivers can worsen frame-time spikes that look like memory compression issues.

7. If you have 8GB of RAM, reduce in-game memory use

   • Lower Texture Quality, Shadow Quality, and Ray Tracing settings first.
   • Close everything except the game.
   • On modern games, 8GB RAM can trigger constant compression and paging; upgrading to 16GB or more is often the long-term fix.
