Detailed analysis
Palworld crashes to desktop after playing for a while, usually once your base gets busy with working Pals. This is a known memory leak — the game's RAM usage climbs steadily the longer you play until your system runs out. The fastest fix: increase your Windows pagefile to 32GB, close everything else, and restart the game every 2-3 hours during long sessions.
What's actually happening
Palworld is built on Unreal Engine 5, and its memory management has a well-documented leak. As you play, the game accumulates memory allocations that it never releases — especially related to Pal AI routines, base production chains, and world streaming. Your RAM usage starts at maybe 8-10GB and creeps up to 14, 16, 18GB over the course of a long session. Eventually it exceeds your physical RAM, Windows starts aggressively paging to disk, and the game either crashes outright with an out-of-memory error or freezes and needs to be force-closed.
This is made worse by the fact that Palworld's base building actively fights your memory. Each Pal assigned to a task runs its own AI loop, pathfinding calculations, and animation state. A fully built base with 15+ working Pals, multiple production lines, and items scattered on the ground is using significantly more memory than exploring the open world with a few Pals in your party.
The most common causes (in order of likelihood)
Memory leak during extended play sessions — This is the primary cause and affects everyone regardless of system specs. Pocketpair has partially addressed it in patches but it hasn't been fully fixed. Sessions longer than 2-3 hours are when crashes start, especially in developed bases.
Insufficient RAM — Palworld's minimum spec says 16GB but in practice, with the memory leak, 16GB gives you about 2-3 hours of stable play. Systems with 8GB RAM crash almost immediately once base building starts. The game doesn't warn you — it just dies.
Small or disabled pagefile — If you disabled your Windows pagefile (virtual memory on disk) or set it to a small fixed size, the game has nowhere to overflow when it exceeds physical RAM. Windows can't page out excess memory and the process gets killed.
Base complexity overload — Large bases with many active Pals, multiple production chains, breeding farms, and item drops on the ground consume dramatically more memory than simple bases. Each working Pal is essentially its own AI agent consuming resources.
Multiplayer server memory scaling — On dedicated servers and co-op, memory usage compounds across all players' bases. Flying over a friend's mega-base while your own base is also loaded can push memory past the breaking point.
How to fix it
Increase your Windows pagefile to at least 32GB. This is the single most impactful fix. Right-click This PC > Properties > Advanced system settings > Performance section > Settings > Advanced tab > Virtual Memory > Change. Uncheck "Automatically manage paging file size." Select your fastest SSD (ideally an NVMe drive), choose Custom size, set Initial size to 16384 MB and Maximum size to 32768 MB. Click Set, then OK, and restart your PC. This gives Windows room to page out memory when Palworld's leak pushes past your physical RAM. The game will stutter briefly during heavy paging, but it won't crash.
Close every background application before launching Palworld. Chrome is the biggest offender — a dozen open tabs can consume 4-8GB of RAM by themselves. Close your browser entirely, not just the window. Close Discord's desktop app and use the mobile app for voice chat instead. Close Spotify, streaming apps, and any game launchers other than Steam. Open Task Manager (Ctrl+Shift+Esc), go to the Details tab, sort by Memory, and kill anything nonessential that's using more than 100MB.
Restart the game every 2-3 hours during long sessions. This is annoying but it's the most reliable workaround for the memory leak until Pocketpair fully fixes it. Save your game, quit to the main menu, close Palworld entirely, and relaunch. Your RAM usage goes back to baseline and you get another 2-3 hours of stable play.
Simplify your base design. Reduce the number of Pals actively working at any given time. Consolidate production lines instead of running many parallel chains. Pick up loose items from the ground — item entities sitting around consume memory. If you have multiple bases, try to avoid having all of them active in the same session by staying near just one.
Lower graphics settings that affect memory. View Distance is the biggest memory consumer — lowering it from Epic to Medium significantly reduces how much world geometry and Pal data is loaded at once. Shadow Quality at Medium instead of Epic saves both VRAM and system RAM. Texture Quality can stay at High unless your GPU has 4GB or less VRAM.
Verify your game files on Steam. Right-click Palworld in your Steam Library > Properties > Installed Files > Verify Integrity of Game Files. Corrupted asset files can cause abnormal memory allocation patterns that accelerate the leak.
Update your GPU driver. Both NVIDIA and AMD have released driver updates with Palworld-specific optimizations. Download the latest driver directly from nvidia.com or amd.com and do a clean install.
For multiplayer, spread bases out geographically. If playing co-op or on a dedicated server, avoid building your base directly next to another player's base. When both bases are in render distance simultaneously, the memory usage of both compounds. Build in different biomes or at least far enough apart that the game doesn't try to load both at once.
Is this a hardware or software problem?
This is a software problem — specifically, a bug in Palworld's memory management. Your hardware isn't failing. However, having more RAM buys you more time before the leak crashes the game. A system with 32GB RAM can play 4-5+ hours before hitting the ceiling, while 16GB systems crash after 2-3 hours. The leak itself is Pocketpair's responsibility to fix, and they've made progress in patches, but it's not fully resolved. If you have the budget, upgrading from 16GB to 32GB RAM is the most effective hardware solution — it helps with many other games too.

Games commonly affected
Palworld's memory leak is specific to Palworld, but similar UE5 memory issues affect ARK: Survival Ascended, Hogwarts Legacy (in dense open-world areas), and many early access UE5 games. If you've increased your pagefile for Palworld, that fix carries over to help with other memory-hungry games as well.
Frequently asked questions
Q: I have 32GB of RAM and Palworld still crashed. Is my RAM bad?
A: Probably not. Even 32GB can be exhausted during very long sessions (5+ hours) with large bases. Check Task Manager right before the crash — if Committed memory is near your total (RAM + pagefile), the leak outran even 32GB. Increase your pagefile further or restart the game more frequently.
Q: Does Palworld perform better on the Xbox/Game Pass version compared to Steam?
A: The Game Pass (Windows) version and Steam version have essentially the same memory leak behavior. Neither platform version is significantly better optimized. Both need the pagefile increase and periodic restarts.
Q: My save file is getting huge. Does save file size affect crashing?
A: Yes, indirectly. Larger save files mean more world state data that needs to stay in memory. If your save file is over 50MB, you have a lot of base structures, captured Pals, and world state. There's not much you can do about save size other than reducing base complexity or starting a fresh world.
