Star Citizen Crashing? Fixes That Actually Work

If Star Citizen keeps crashing on your PC, you are not alone—it is one of the most common complaints about the game, and the causes range from outdated drivers to a full pagefile. This guide walks you through the most likely fixes in order, from quick checks to deeper system adjustments, so you can get back into the ‘verse without the desktop interrupting you.

Why Star Citizen Crashes So Often

Star Citizen is a massively ambitious, still-in-development game that pushes hardware harder than almost anything else on the market. Its alpha status means the code is not fully optimized, and crashes can come from the game itself, your operating system, or your specific hardware configuration. Common culprits include:

• Outdated or corrupted GPU drivers—the most frequent cause of graphics-related crashes.
• Insufficient virtual memory (pagefile)—the game can use 20+ GB of RAM, and if your system runs out, it crashes.
• Overheating components—CPUs and GPUs that hit thermal limits will shut down or crash.
• Corrupted game files—a bad patch or interrupted download can leave files that cause instability.
• Background software conflicts—overlays, antivirus, or RGB utilities can interfere with the game’s anti-cheat or rendering.

Quick Fixes to Try First

Before you dig into advanced settings, run through these five steps. They resolve a large percentage of crashes and take less than ten minutes total.

1. Update your GPU drivers. Go to the NVIDIA or AMD website, download the latest driver for your card, and do a clean install (in NVIDIA’s installer, check “Perform a clean installation”).
2. Verify game files. In the RSI Launcher, click the gear icon next to “Play,” then select “Verify.” This checks all files and re-downloads any that are corrupt.
3. Disable fullscreen optimizations. Right-click the Star Citizen executable (usually in C:\Program Files\Roberts Space Industries\StarCitizen\LIVE\), go to Properties > Compatibility, and check “Disable fullscreen optimizations.” Also check “Run this program as an administrator.”
4. Close background overlays. Exit Discord, GeForce Experience, MSI Afterburner, or any app that draws on top of the game. Test after each one to find the culprit.
5. Run the game in windowed mode. In the game’s settings, change the display mode to “Windowed” or “Borderless.” Some users see fewer crashes with these modes than with fullscreen.

Fix the Pagefile (Virtual Memory)

Star Citizen is memory-hungry. It can use 16–20 GB of RAM, and if you have 16 GB, Windows will rely heavily on the pagefile—a portion of your SSD used as extra memory. If the pagefile is too small or on a slow drive, the game crashes with an “Out of memory” error or just closes.

To fix this, set a custom pagefile size on your fastest SSD:

1. Press Windows + R, type sysdm.cpl, and press Enter.
2. Go to the Advanced tab, then under Performance, click Settings.
3. In the new window, go to the Advanced tab and click Change under Virtual Memory.
4. Uncheck “Automatically manage paging file size for all drives.”
5. Select your fastest SSD (preferably the one where the game is installed), choose Custom size, and set Initial and Maximum to 16384 MB (16 GB) or higher—some players use 32 GB.
6. Click Set, then OK, and restart your PC.

If you have 32 GB of RAM, you may still want a pagefile of at least 8 GB, as some crashes occur even with ample RAM.

Check Temperatures and Power Settings

Overheating is a silent killer. If your CPU or GPU reaches its thermal limit, the system will crash to protect the hardware. Use a free tool like HWMonitor or MSI Afterburner to check temperatures while playing. Normal ranges are roughly:

• CPU: 50–85°C under load, depending on the model.
• GPU: 60–85°C under load.

If you see temperatures above 90°C, clean your fans, check your thermal paste, and ensure your case has good airflow. Also, in Windows, set your power plan to High Performance (Settings > System > Power & sleep > Additional power settings). This prevents the CPU from downclocking, which can cause stutters that sometimes trigger crashes. Note that some CPUs run hot by design, so check your specific model’s safe range.

Adjust In-Game Graphics Settings

Star Citizen’s graphics options are not all created equal. Some settings cause crashes or severe instability on certain hardware. Try these changes:

• Set Graphics Quality to High (not Very High). Very High is poorly optimized and can cause memory spikes.
• Turn Volumetric Clouds to Off or Medium. This setting is a major performance and stability drain.
• Set Field of View to around 90—higher values can cause issues on some systems.
• Disable Motion Blur and Depth of Field. They add load without much benefit.
• If you have an NVIDIA card, set Shader Cache in the NVIDIA Control Panel to Unlimited for the game’s executable.

Reinstall the Game (Last Resort)

If none of the above works, a clean reinstall often fixes crashes caused by corrupted files that the verify tool misses. Here’s how to do it properly:

1. In the RSI Launcher, click the gear icon and select Uninstall.
2. Manually delete the entire StarCitizen folder from your install directory to remove leftover files.
3. Also delete the %appdata%\rsilauncher folder (press Windows+R, type %appdata%, and find it).
4. Restart your PC, reinstall the launcher, and download the game fresh.

This takes time, but it clears any hidden corruption. Only do this after trying the other fixes, since the download is 80+ GB.

Frequently Asked Questions

Why does Star Citizen crash to desktop without an error?

This is usually a memory or driver issue. Check your pagefile size, update your GPU drivers, and look in Windows Event Viewer (under Windows Logs > Application) for an error code. If you see “0xc0000005” (access violation), it’s often a corrupted file or driver conflict.

Does Star Citizen crash on high-end PCs too?

Yes. Even with a top-tier CPU and GPU, the game’s alpha state can crash due to server-side issues or memory leaks. High-end hardware reduces but does not eliminate crashes.

Is there a way to see what caused the crash?

Yes. Look in %appdata%\Roberts Space Industries\StarCitizen\LIVE\ for a folder called game.log. Open it and search for “ERROR” or “CRASH”. The last few lines often indicate the cause, such as a missing file or a GPU error.

Should I overclock my CPU/GPU to improve stability?

No. Overclocking can make crashes more frequent. If you have an overclock applied, revert to stock clocks and test. Stability is more important than a few extra frames in Star Citizen.

Does running the game on an HDD cause crashes?

Yes, often. Star Citizen streams assets constantly, and an HDD cannot keep up, leading to stutters and sometimes crashes. The game requires an SSD for acceptable performance and stability.

Can antivirus software cause crashes?

Yes. Some antivirus programs quarantine or block game files. Add the Star Citizen folder and the launcher to your antivirus’s exclusion list, or temporarily disable it to test.
