How to Fix No Man’s Sky Crashing, Stuttering & Freezing

You are about to land on a lush, undiscovered planet after hours of warping across the galaxy, only for the screen to violently freeze, the audio to loop indefinitely, and your desktop to suddenly appear. Dealing with No Man’s Sky crashing, stuttering, and freezing is a massive buzzkill, especially when you lose unsaved progress in this infinite, procedurally generated universe [1]. Because this game heavily relies on real-time generation of planets, creatures, and environments, it taxes your hardware in unique and often frustrating ways.

TL;DR: The Short Answer

No official fix has been confirmed yet for every single hardware combination, but based on extensive community reports, you can resolve most performance issues by following these immediate steps:

• Delete the Shader Cache: Clear out old compiled shaders that conflict with new game updates.
• Lower Volumetric Effects: Drop this specific setting to “Standard” or “Enhanced” to relieve massive GPU strain on planetary surfaces.
• Disable Multiplayer: Turn off network features temporarily to prevent desync freezes when entering the Space Anomaly.
• Verify Game Files: Use Steam to check for corrupted installation files [1].
• Update GPU Drivers: Ensure you are on the latest Nvidia, AMD, or Intel drivers optimized for the latest No Man’s Sky expeditions.

Understanding the Engine: Why No Man’s Sky Struggles

Before diving into the fixes, it is crucial to understand what your PC is actually doing when you play this game. No Man’s Sky is a science-fiction exploration game built on a custom engine designed to render a procedurally generated universe [1][2]. Unlike traditional games where maps are pre-baked and loaded from your SSD, No Man’s Sky uses complex mathematical algorithms to generate terrain, flora, fauna, and weather systems on the fly as you fly your ship toward a planet [3].

This sandbox mechanic means your CPU is constantly crunching math, while your GPU is desperately trying to draw the results in real-time. When you experience No Man’s Sky stuttering, it is usually because your CPU cannot feed data to your GPU fast enough, or your RAM is bottlenecking the procedural generation process. Freezing and crashing often occur when the game engine requests a texture or a shader that is corrupted or takes too long to load.

Step 1: The Shader Cache Wipe (Fixing Micro-Stutters)

Based on community reports, the number one cause of severe stuttering—especially after a major game update—is a corrupted shader cache. Every time you encounter a new biome, the game compiles shaders. If old data conflicts with new data, the game engine trips over itself.

How to Clear the Cache on Steam

1. Open your Windows File Explorer.
2. Navigate to your Steam installation folder (usually C:\Program Files (x86)\Steam\steamapps\common\No Man's Sky\GAMEDATA\SHADERCACHE).
3. Delete all the files inside this folder. Do not delete the folder itself, just the contents.
4. Next, clear your GPU’s specific shader cache. For Nvidia users, this is found in %localappdata%\NVIDIA\DXCache and GLCache. Delete the contents of these folders.
5. Restart your PC and launch the game.

Warning: The first time you load into the game after doing this, No Man’s Sky will stutter heavily for about 5 to 10 minutes. This is normal! The game is rebuilding a fresh, uncorrupted cache. Let it run, and the performance will smooth out beautifully.

Step 2: Optimizing In-Game Graphics Settings

Not all graphics settings are created equal. Because No Man’s Sky emphasizes player freedom and discovery [1], you will seamlessly transition from the cold vacuum of space (low resource cost) to dense, stormy jungle planets (extreme resource cost). You need settings that can handle both extremes without freezing.

The Problematic Settings

• Volumetric Effects: This controls the rendering of clouds, fog, and atmospheric scattering. It is notoriously poorly optimized. Lowering this from “Ultra” to “Standard” can instantly yield a 15-20 FPS boost and stop sudden crashes when entering a planet’s atmosphere.
• Base Complexity: If your game freezes specifically when approaching your base, this is the culprit. Set this to “Standard.” Rendering thousands of player-placed building pieces strains the engine’s memory limits.
• Planet Quality: This dictates the density of the procedurally generated terrain [2]. If you are experiencing heavy CPU bottlenecks (stuttering while running on foot), lower this setting.

Once your game is running smoothly and your framerate is stable, you will want to ensure your exploration gear is top-notch.

Step 3: Steam and Windows System Tweaks

Sometimes, the issue isn’t the game itself, but how Windows is prioritizing it. Sandbox games without specific goals [1] can run for hours, leading to memory leaks if your system isn’t optimized.

Verify Integrity of Game Files

Always start here. Steam updates can sometimes drop packets, resulting in corrupted files that cause hard crashes to the desktop.

1. Right-click No Man’s Sky in your Steam Library.
2. Select Properties > Installed Files.
3. Click Verify integrity of game files. Let Steam scan and redownload any missing data.

Disable Background Overlays

Overlays from Steam, Discord, and Nvidia GeForce Experience hook into the game’s rendering pipeline. Based on community reports, these hooks can cause No Man’s Sky to freeze, especially when receiving a notification. Disable all overlays in their respective settings menus.

Windows High-Performance Mode

Ensure Windows isn’t throttling your hardware. Go to Windows Settings > System > Display > Graphics. Browse for the NMS.exe file, add it to the list, and explicitly set it to High Performance so it utilizes your dedicated GPU to its maximum potential.

Step 4: Network and Multiplayer Desync Fixes

No Man’s Sky combines elements of survival, trading, and space travel [1], and it allows you to do this alongside other players. However, the multiplayer implementation can be incredibly unstable.

When you summon the Space Anomaly (the multiplayer hub), your game suddenly has to load the customized character models, ships, and pets of up to 32 other players. This massive data spike is a prime trigger for freezing.

The Fix: If you are playing solo or doing a permadeath run, go to the in-game Network Settings and disable Multiplayer. This stops the game from constantly pinging matchmaking servers and trying to sync other players’ coordinates in your procedurally generated universe. You can still upload your discoveries to the server while multiplayer is disabled.

The Ultimate Shortcut: Using XMODhub

Let’s be brutally honest: spending hours tweaking configuration files, updating drivers, and restarting your PC just to make a game playable is exhausting. When No Man’s Sky crashes right after you’ve spent two hours mining activated copper, the loss of progress can make you want to uninstall the game entirely.

Advanced Engine Tweaks: Editing TKGRAPHICSSETTINGS.MXML

If you are still experiencing No Man’s Sky stuttering after exhausting basic in-game adjustments, the core issue likely stems from how the engine allocates CPU threads. By default, the game often miscalculates your processor’s logical cores, leading to severe bottlenecks when loading massive procedurally generated terrain or entering a dense Space Station.

To manually override this and force the game to utilize your CPU properly, you must edit the core configuration file.

1. Navigate to your local settings folder: \Steam\steamapps\common\No Man's Sky\Binaries\SETTINGS.
2. Open the file named TKGRAPHICSSETTINGS.MXML using Notepad or any basic text editor.
3. Press Ctrl + F and search for and .
4. Adjust the value= numbers based on your specific CPU architecture.

Use the following community-tested data table to find the optimal thread allocation for your rig:

Note: Save the file and restart the game. Setting NumLowThreads to 0 on high-end processors forces the engine to stop offloading critical physics and rendering tasks to slower efficiency cores, which is a massive fix for late-game freezing.

Optimizing Upscaling: DLSS vs. FSR

Running out of VRAM during a Hyperdrive jump is a guaranteed way to crash to the desktop. To relieve memory pressure, you must utilize modern upscaling. If you own an RTX graphics card, navigate to the Anti-Aliasing settings and enable Nvidia DLSS, setting it to “Quality” or “Balanced”. If you are on an AMD GPU, older Nvidia card, or Steam Deck, enable AMD FSR 2.0. These technologies render the game at a lower base resolution and upscale it, drastically reducing the VRAM footprint while keeping the visuals crisp.
