DirectX errors are among the most frustrating problems PC gamers face. Whether your game refuses to launch, crashes during gameplay, or suddenly drops from smooth frame rates to a frozen screen, a DirectX error can completely ruin the experience.
The good news is that most DirectX issues are software-related and can be fixed without replacing hardware. In this guide, you’ll learn how to fix DirectX errors in games, restore stable FPS performance, and get back to gaming as quickly as possible.
What Is a DirectX Error and Why Does It Affect Your Game’s FPS?
Understanding the DirectX Error
DirectX is Microsoft’s collection of graphics and multimedia APIs that allow games to communicate with your GPU. Modern games rely heavily on DirectX to render graphics, process effects, and maintain smooth frame rates.
When a DirectX component becomes corrupted, outdated, or incompatible, the game may:
- Fail to launch
- Crash during gameplay
- Experience severe FPS drops
- Freeze or stutter unexpectedly
A DirectX runtime error often prevents the game from loading entirely, resulting in 0 FPS. Other DirectX issues may allow the game to run but cause severe frame pacing problems and instability.
Most Common DirectX Error Types in PC Games
| Error Type | What It Means | Games Commonly Affected |
| DirectX Runtime Error | Missing or corrupted runtime files | Valorant, FIFA 18, EA FC 26 |
| DirectX Encountered an Unrecoverable Error | GPU or driver crash | Black Ops 6, Call of Duty |
| DirectX Internal System Error | Windows-level DirectX conflict | Various PC games |
| DirectX Function Error | Failed DirectX API call | FIFA 18, older EA titles |
| DirectX Network Error | Multiplayer initialization failure | Online games |
| DirectX 12 Error | DX12 compatibility issue | Baldur’s Gate 3, BO6, EA FC 26 |
What Causes a DirectX Error in PC Games?
Hardware and Driver-Related Causes
Several hardware-related issues can trigger DirectX errors:
- Outdated graphics drivers
- Corrupted GPU driver installations
- GPU overheating
- Unstable GPU overclocks
- Unsupported DirectX feature levels
Many gamers discover that updating their NVIDIA, AMD, or Intel drivers immediately resolves the issue.
Software and System-Level Causes
DirectX errors can also originate from Windows itself.
Common causes include:
- Missing DirectX runtime files
- Corrupted game installations
- Damaged Windows system files
- Visual C++ dependency conflicts
- DirectX version mismatches
For example, if a game requires DirectX 12 but your system is configured incorrectly or missing required components, launch failures may occur.
Windows 11-Specific DirectX Error Triggers
Windows 11 introduces additional security and virtualization features that occasionally conflict with gaming applications.
Potential causes include:
- Virtualization-Based Security (VBS)
- Hypervisor-Protected Code Integrity (HVCI)
- Hardware Accelerated GPU Scheduling conflicts
- Driver signature compatibility issues
How to Fix DirectX Error in Games — Step-by-Step General Fixes
Fix 1 — Update Your GPU Drivers (Most Effective First Step)
Outdated graphics drivers are the most common reason behind DirectX runtime errors.
If performance problems continue after updating your graphics drivers, our guide on What PC Parts Affect Gaming the Most? (Complete FPS Performance Guide) explains which hardware components have the biggest impact on frame rates and overall gaming performance
Update your drivers through:
- NVIDIA App or GeForce Experience
- AMD Adrenalin Software
- Intel Arc Control
- Device Manager (less reliable)
If you’ve upgraded GPUs recently, perform a clean driver installation rather than a standard update.
Fix 2 — Reinstall DirectX Runtime Components
If you’re wondering how to repair DirectX, reinstalling runtime components is often the fastest solution.
Steps:
- Download Microsoft’s DirectX End-User Runtime Web Installer.
- Close all running games.
- Run the installer.
- Restart your PC.
- Launch the game again.
This process repairs missing or corrupted DirectX libraries used by thousands of PC games.
Fix 3 — Run the DirectX Diagnostic Tool (DxDiag)
DxDiag helps identify DirectX-related issues.
Steps:
- Press Windows + R
- Type dxdiag
- Press Enter
Check:
- DirectX Version
- Display Tab
- Driver Date
- Feature Levels
- Error messages
DxDiag is especially useful when diagnosing DirectX 12 compatibility problems.
Fix 4 — Update Windows and DirectX Version
Windows updates frequently include DirectX fixes and compatibility patches.
To update:
- Open Settings
- Navigate to Windows Update
- Check for updates
- Install all available updates
- Restart your system
Keeping Windows current improves compatibility with modern games and reduces DirectX crashes.
Fix 5 — Verify Game File Integrity
Corrupted game files often trigger DirectX errors.
Platform-specific repair methods:
Steam
- Library → Properties → Installed Files → Verify Integrity
EA App
- Manage → Repair
Battle.net
- Scan and Repair
Repairing corrupted files frequently resolves launch-related DirectX issues.
Fix 6 — Adjust In-Game Graphics API Settings
Many games support multiple graphics APIs.
If DirectX 12 causes crashes:
- Switch to DirectX 11
- Disable experimental rendering options
- Reduce VRAM-heavy settings
Games such as Black Ops 6, EA FC 26, Baldur’s Gate 3, and Valorant often become more stable under DX11.
Fix 7 — Disable Overclocking and GPU Stress
Aggressive overclocking can cause DirectX to crash under heavy load.
DirectX crashes can sometimes be caused by unstable hardware rather than software issues. If you’re unsure whether your graphics card is functioning correctly, check our guide on How to Check If Your GPU Is Performing Well FPS & Health for detailed troubleshooting steps.
Return:
- GPU Core Clock to stock settings
- Memory Clock to default values
- Voltage modifications to default
Many “DirectX Encountered an Unrecoverable Error” messages disappear after restoring factory GPU settings.

For additional system-level optimizations, see our guide on Optimize Windows 11 for Gaming FPS Boost Settings (2025) to improve stability and reduce gaming-related software conflicts.
Windows 11 DirectX Compatibility Checklist
Before troubleshooting further, confirm:
- Your GPU supports DirectX 12
- Latest GPU drivers are installed
- Hardware Accelerated GPU Scheduling is disabled for testing
- VBS is not interfering with gaming performance
Fixing DirectX Error After Windows 11 Update
If the error appeared after a Windows update:
- Reinstall DirectX Runtime.
- Verify game files.
- Run System File Checker.
Open Command Prompt as Administrator and enter:
sfc /scannow
This repairs corrupted Windows system files that may affect DirectX functionality.
How to Fix DirectX 12 Error in Games
Why DirectX 12 Errors Are Different From DirectX 11 Errors
DirectX 12 gives developers lower-level hardware access and better CPU utilization.
However, this increased complexity means:
- More driver dependencies
- Greater VRAM pressure
- Increased sensitivity to unstable hardware
Unlike DX11, DX12 crashes often result in immediate game shutdowns rather than gradual FPS degradation.
DirectX 12 Error Fix Checklist
- Confirm DirectX 12 support
- Update GPU drivers
- Disable Ray Tracing
- Test DX11 mode
- Enable Maximum Performance power mode
- Disable Resizable BAR or Smart Access Memory temporarily
- Monitor GPU temperatures
