Fix Forza Horizon 3 PC Crashing: Proven Solutions

If Forza Horizon 3 keeps crashing on your PC, the fix usually comes down to updating your graphics drivers, disabling the in-game overlay, and adjusting a few Windows settings. This article walks you through the most effective solutions, from quick checks to deeper system tweaks, so you can get back to racing without interruptions.

Why Forza Horizon 3 Crashes on PC

Forza Horizon 3 was released in 2016 and is known for being sensitive to system configurations and software conflicts. Common causes include outdated or incompatible graphics drivers, Windows 10 build issues, overlay software like Discord or GeForce Experience, and corrupted game files. The game also has a known memory leak that can cause crashes during long sessions, especially on systems with less than 16GB of RAM.

Before You Start: Basic Checks

Before diving into advanced fixes, make sure your system meets the minimum requirements and that your Windows is up to date. The game requires a 64-bit processor, 8GB of RAM (16GB recommended), and a DirectX 12 capable GPU. Also, verify that your game installation is complete and not corrupted.

Restart your PC to clear temporary glitches.
Close background apps that might conflict (browsers, Discord, etc.).
Ensure you have at least 30GB of free disk space for the game and its updates.

Update Your Graphics Drivers

Outdated GPU drivers are the number one cause of crashes in Forza Horizon 3. Both NVIDIA and AMD release drivers optimized for this title. Go to the official website of your GPU manufacturer (NVIDIA or AMD) and download the latest driver for your specific card model. Use the “clean installation” option if available to remove old driver remnants.

If you already have the latest driver, try rolling back to an older version, as some recent drivers have introduced stability issues with this older game.

Disable Overlay and Recording Software

Overlay apps like Discord, GeForce Experience, and MSI Afterburner can interfere with Forza Horizon 3’s rendering and cause crashes. Temporarily disable these overlays and any in-game recording features. For GeForce Experience, you can turn off the in-game overlay in its settings. For Discord, go to User Settings > Overlay and toggle it off. If the game stops crashing, you’ve found the culprit.

Adjust Windows Settings for Stability

Forza Horizon 3 is known to have issues with certain Windows 10 versions. Try these tweaks:

Disable fullscreen optimizations: Right-click the game’s .exe file (usually in the WindowsApps folder or via the shortcut), go to Properties > Compatibility, and check “Disable fullscreen optimizations.”
Run as administrator: In the same Compatibility tab, check “Run this program as an administrator.”
Disable Game Mode: Go to Settings > Gaming > Game Mode and turn it off. Also, disable Game Bar and any game DVR features.
Update Windows: Ensure you have the latest Windows 10 updates installed, as Microsoft has released patches that improve stability for this game.

Verify Game Files and Reinstall

Corrupted game files are another common cause. If you bought the game on the Microsoft Store, open the Store, go to Library, and use the “Update” button. For the Steam version, right-click the game in your library, select Properties > Local Files > Verify Integrity of Game Files. If that doesn’t help, uninstall and reinstall the game completely. This often fixes stubborn crashes.

Fix the “Out of Memory” Crash

Many players report a specific crash that says “Out of memory” or simply closes the game after a few minutes. This is typically due to a memory leak. Workarounds include:

Lowering the graphics settings, especially texture quality and anti-aliasing.
Playing in windowed or borderless mode instead of fullscreen.
Closing other memory-hungry apps like Chrome.
If you have less than 16GB RAM, consider upgrading, as the game can use up to 12GB in some areas.

Advanced: Registry and Compatibility Mode

Some users have fixed crashes by forcing the game to run in Windows 8 compatibility mode. Right-click the game executable, go to Properties > Compatibility, and check “Run this program in compatibility mode for: Windows 8.” This can resolve issues with newer Windows versions. Another advanced fix is to add the game’s executable to the Windows Defender exclusion list, as real-time scanning can sometimes interfere with the game’s loading process.

Frequently Asked Questions

Why does Forza Horizon 3 crash on startup?

Startup crashes are usually caused by outdated drivers or missing Windows updates. Ensure your GPU drivers are current, and try the compatibility mode trick (Windows 8) for the game’s executable. Also, disable any overlay software before launching.

Will lowering graphics settings reduce crashes?

Yes, lowering graphics settings can help, especially if the crash is due to memory or GPU instability. Reduce texture quality, shadow quality, and anti-aliasing. This reduces the load on your system and can prevent crashes during intense scenes.

Is there a known fix for the memory leak?

There is no official fix, but community workarounds include playing in windowed mode, limiting the frame rate to 60 FPS, and restarting the game every couple of hours. Increasing your system RAM to 16GB or more also helps significantly.

Does Forza Horizon 3 run better on Windows 11?

Forza Horizon 3 is not officially supported on Windows 11, but many players run it successfully. If you’re on Windows 11 and experiencing crashes, try the compatibility mode for Windows 10 or 8, and ensure your drivers are up to date.

Can I fix crashes by reinstalling the game?

Yes, reinstalling can fix crashes caused by corrupted game files. Make sure to back up your save data first, as reinstalling may not preserve it. After reinstalling, install the latest updates and try the game.
