How to Fix Palworld Lag and Crashes by Changing Virtual Memory Settings

After spending dozens of hours exploring Palworld, building massive bases, breeding stronger Pals, and fighting powerful enemies, there is one problem that can completely ruin the experience: unstable performance. Few things are more frustrating than preparing for a boss fight, flying across the map on a fast mount, or managing a busy base only to suddenly experience freezing, FPS drops, heavy stuttering, or a crash straight to the desktop.

From my experience playing countless survival and open-world games, performance issues like this are not unusual. Large games constantly push hardware with world streaming, AI calculations, physics systems, and huge amounts of background data. Palworld is especially demanding because it combines base building, creature management, multiplayer features, and a massive open environment running on Unreal Engine.

One of the most recommended solutions among the Palworld community is changing Windows Virtual Memory settings, also known as the paging file. This adjustment will not magically upgrade your hardware, but it can create an important safety buffer when the game starts consuming more memory than your system can comfortably handle.

This guide explains why Palworld suffers from memory-related crashes, how Windows Virtual Memory works, and how to configure it correctly to reduce lag, improve stability, and prevent unexpected crashes during long gaming sessions.

Why Palworld Experiences Lag and Memory Crashes

Palworld is a surprisingly demanding survival game. The combination of an open-world map, construction mechanics, active Pals, multiplayer features, and constant background calculations creates a heavy workload for both your CPU and memory system.

The biggest issue many players encounter is related to possible memory leaks. A memory leak happens when a game continues using RAM but does not properly release unused data after it is no longer required. Over time, the amount of occupied memory slowly increases until the system begins struggling.

For example, during a long play session, Palworld constantly loads and manages different types of information:

• New terrain areas and map sections
• Pal animations and AI behavior
• Base structures and production systems
• Textures, visual effects, and world objects
• Enemy encounters and combat data

Normally, a game should remove unnecessary information from memory when it is no longer needed. However, when memory management problems occur, RAM usage can continue growing even after leaving areas or finishing activities.

Once your physical RAM reaches around 95% to 100% usage, Windows begins searching for additional space through Virtual Memory. If your paging file is too small, disabled, or placed on a slow storage drive, the result can be severe performance problems.

Players commonly experience symptoms such as:

• Sudden FPS drops during exploration
• Short freezes when entering new areas
• Delayed controls and input lag
• Textures loading incorrectly
• Unreal Engine crashes
• ’Out of Video Memory’ errors

The frustrating part is that these problems can appear even on gaming PCs that meet or exceed Palworld’s recommended system requirements.

What Is Windows Virtual Memory and Why Does It Help?

Virtual Memory is a built-in Windows feature that works as an extension of your physical RAM. When your system runs out of available memory, Windows temporarily transfers less important data from RAM into a hidden file called pagefile.sys, which is stored on your drive.

You can think of Virtual Memory as an emergency storage area that prevents your computer from immediately running out of resources. Your RAM is extremely fast but limited, while your SSD provides much more available space but works slower. The paging file creates a backup system between the two.

By default, Windows automatically controls the size of the paging file. For everyday tasks, this works perfectly. Browsing websites, watching videos, or working with documents usually does not create enough memory pressure to cause problems.

However, demanding games like Palworld are different. During long sessions, especially with large bases and multiplayer worlds, memory usage can increase rapidly. Windows may need to resize the paging file dynamically, and this process can create temporary freezes and noticeable stuttering.

Manually setting a larger fixed Virtual Memory size gives your system a permanent memory reserve. Instead of constantly adjusting the pagefile during gameplay, Windows already has additional space available when Palworld needs it.

How to Increase Virtual Memory for Palworld

The following method works on both Windows 10 and Windows 11. The entire process only takes a few minutes and can significantly improve stability for players suffering from memory-related crashes.

Step 1: Open Advanced System Settings

Press the Windows key and search for:

Advanced System Settings

Open the result to access the System Properties menu.

Step 2: Enter Performance Settings

Inside the System Properties window:

• Open the Advanced tab.
• Find the Performance section.
• Click the Settings button.

This menu controls different Windows performance options, including memory management settings.

Step 3: Open Virtual Memory Options

Inside the Performance Options window:

• Select the Advanced tab.
• Locate the Virtual Memory section.
• Click Change.

You will now see the current paging file configuration for your storage drives.

Step 4: Disable Automatic Pagefile Management

At the top of the Virtual Memory window, find the option:

Automatically manage paging file size for all drives

Remove the checkmark from this option. This allows you to manually configure the amount of Virtual Memory Windows can use.

Step 5: Choose the Correct Storage Drive

Select the drive where you want to create the paging file. The best option is always your fastest SSD, especially:

• NVMe SSD drives
• Modern SATA SSD drives

Avoid placing Virtual Memory on older mechanical HDD drives. While it technically works, the slower read and write speeds can create additional stuttering during gameplay.

Step 6: Set a Custom Virtual Memory Size

Select the Custom size option. You will see two fields:

• Initial size (MB)
• Maximum size (MB)

A commonly recommended configuration is based on your installed RAM amount.

The recommended formula is simple:

Initial Size: RAM × 1.5

Maximum Size: RAM × 3

Remember that Windows uses megabytes, so 1GB equals 1024MB.

For example, a 16GB RAM system contains 16384MB. The initial size would be 16384 × 1.5 = 24576MB, while the maximum size would be 16384 × 3 = 49152MB.

Step 7: Save Changes and Restart Your PC

After entering your values:

• Click Set.
• Press OK.
• Apply all changes.
• Restart your computer.

The restart is necessary because Windows needs to rebuild the memory allocation system and apply the new paging file configuration.

Extra Palworld Optimization Tips for Better Performance

Increasing Virtual Memory can reduce crashes, but combining it with additional optimizations will create a much smoother experience. These small changes can help maintain better FPS and reduce unnecessary memory usage.

Reduce Dropped Items in the World

Palworld worlds can quickly become filled with dropped resources, especially after long farming sessions. Every object left on the ground requires additional tracking and can increase memory usage.

Before loading your save file:

• Open World Settings.
• Find Max Dropped Items in World.
• Lower the value to reduce unnecessary objects.

This is especially helpful for players with large bases or older systems.

Restart Palworld During Long Sessions

This is one of the simplest and most effective habits for survival games with memory issues. After several hours, restarting the game clears temporary memory usage and gives the engine a fresh start.

A good routine is:

• Save your progress.
• Exit Palworld completely.
• Launch the game again.

Doing this every few hours can prevent performance from slowly degrading during extended play sessions.

Adjust Heavy Graphics Settings

Some graphical options create additional stress during large battles and busy base areas. Lowering a few settings can improve frame stability.

Try adjusting:

• Anti-Aliasing quality
• Shadow quality
• Effects quality
• View distance

Changing Anti-Aliasing from TSR to FXAA may help reduce sudden FPS drops during intense fights. Disabling VSync can also improve frame consistency on some systems.

Final Thoughts

Palworld is one of those games where performance problems can appear after many hours of exploration, building, and resource management. The game constantly pushes your hardware with world streaming, AI calculations, and large amounts of active data.

Changing Windows Virtual Memory settings will not replace upgrading your RAM or buying better hardware, but it can provide an important safety net when Palworld starts reaching memory limits. For many players, increasing the paging file size helps reduce crashes, lower stuttering, and improve stability during longer sessions.

If you are tired of losing progress because Palworld freezes after hours of gameplay, adjusting your pagefile settings is one of the easiest fixes worth trying. Combine it with cleaner world settings, optimized graphics options, and regular restarts, and your adventures across the Palpagos Islands should become much smoother.
