If you are experiencing any combination of Forza Horizon 6 error codes FHE01, FHC01, and FHD01 alongside Out of Video Memory warnings or video card crashes, you are dealing with a layered GPU resource failure that combines engine initialization errors, video card communication failures, and VRAM exhaustion into a single disruptive experience. These three error codes frequently appear together and share overlapping root causes that can be addressed through a structured set of fixes.

This guide covers every verified fix for Forza Horizon 6 FHE01, FHC01, FHD01, Out of Video Memory, and video card crash errors on Windows PC.

What Causes FHE01, FHC01, FHD01, Out of Video Memory, and Video Card Crashes

  • Insufficient VRAM for Forza Horizon 6’s default Ultra or High texture quality settings
  • Outdated or corrupted GPU drivers failing to manage VRAM allocation correctly
  • Hardware-Accelerated GPU Scheduling causing VRAM management instability
  • GPU overclocking producing memory timing errors under sustained VRAM load
  • Corrupted shader cache causing the rendering pipeline to exhaust VRAM during compilation
  • DirectX 12 initialization failure producing cascading FHE01 and FHD01 engine errors
  • Gaming Services conflicts triggering FHE01 engine errors alongside GPU failures
  • Thermal throttling reducing GPU performance and triggering video card crash codes
  • Multiple applications consuming VRAM simultaneously leaving insufficient resources for the game

How to Fix Forza Horizon 6 FHE01, FHC01, FHD01, Out of Video Memory, and Video Card Crashes

Fix 1: Lower In-Game Graphics Settings to Reduce VRAM Usage

Out of Video Memory errors and the FHC01 and FHD01 crash codes most commonly occur when Forza Horizon 6’s default settings exceed your GPU’s available VRAM. Reducing these settings immediately resolves VRAM exhaustion crashes.

Steps:

  • Launch Forza Horizon 6 and navigate to Settings, then Video or Graphics
  • Lower the following settings immediately: Texture Quality from Ultra to High or Medium Shadow Quality from Ultra to High Reflection Quality from Ultra to Medium Disable Ray Tracing completely if currently enabled Lower Anisotropic Filtering from 16x to 8x or 4x
  • Apply the settings and restart the game to test under normal gameplay conditions

Fix 2: Perform a Clean GPU Driver Installation

Outdated or partially corrupted GPU drivers mismanage VRAM allocation and fail to communicate correctly with the Forza Horizon 6 rendering engine, producing all three crash codes simultaneously.

Steps:

  • Download DDU and the latest GPU driver from your manufacturer’s official website
  • Boot into Safe Mode through msconfig, Boot tab, Safe Boot
  • Run DDU, select GPU and your manufacturer, then click Clean and Restart
  • After restarting normally, install the latest GPU driver with Clean Installation selected
  • Restart your PC after installation and relaunch Forza Horizon 6

Fix 3: Disable Hardware-Accelerated GPU Scheduling

Hardware-Accelerated GPU Scheduling interferes with VRAM allocation management in Forza Horizon 6, contributing to Out of Video Memory errors and the FHC01 and FHD01 crash codes under heavy rendering load.

Steps:

  • Press Win + I and go to System, then Display
  • Click Graphics, then Change Default Graphics Settings
  • Toggle Hardware-Accelerated GPU Scheduling to Off
  • Restart your PC and relaunch Forza Horizon 6

Fix 4: Revert GPU Overclock to Stock Settings

GPU overclocking introduces VRAM timing instability that causes Out of Video Memory errors and video card crashes at Forza Horizon 6’s sustained rendering load. Stock speeds eliminate this instability directly.

Steps:

  • Open MSI Afterburner or your overclocking software
  • Reset all core clock, memory clock, and voltage offsets to default stock values
  • Click Apply to save the stock configuration
  • If overclocked through BIOS, restart and load optimized defaults
  • Relaunch Forza Horizon 6 and monitor for crashes

Fix 5: Clear the Shader Cache

A corrupted shader cache causes the GPU to exhaust VRAM during shader compilation, triggering Out of Video Memory errors and the FHC01 crash code during the first loading sequence.

Steps:

  • Press Win + R and type %localappdata% then press Enter
  • Navigate to Forza Horizon 6, open the Saved folder
  • Delete the ShaderCache and PipelineCaches folders
  • Also clear the GPU shader cache through NVIDIA Control Panel or AMD Software
  • Restart your PC and relaunch the game

Fix 6: Repair Gaming Services to Resolve FHE01

The FHE01 error appearing alongside FHC01 and FHD01 indicates a Gaming Services conflict compounding the GPU resource failures. Reinstalling Gaming Services addresses the FHE01 component of the combined error.

Steps:

  • Open Windows Terminal as Administrator
  • Run: Get-AppxPackage -allusers Microsoft.GamingServices | Remove-AppxPackage -allusers
  • Then run: start ms-windows-store://pdp/?productid=9MWPM2CQNLHN
  • Install Gaming Services fresh and restart your PC

Fix 7: Monitor GPU Temperature and Address Thermal Issues

Thermal throttling under Forza Horizon 6’s sustained GPU load reduces VRAM bandwidth and triggers video card crash codes when the GPU cannot maintain stable operation at its rated clock speeds.

Steps:

  • Download MSI Afterburner or HWiNFO64 and monitor GPU temperature during gameplay
  • If temperatures exceed 85 degrees Celsius consistently, thermal throttling is occurring
  • Clean your GPU heatsink and fans of dust accumulation using compressed air
  • Improve case airflow by checking all intake and exhaust fans are functioning
  • Consider reapplying thermal paste to the GPU die if temperatures remain elevated
  • Retest Forza Horizon 6 after addressing thermal issues

Fix 8: Disable Memory Integrity and Hyper-V

Steps:

  • Open Windows Security, go to Device Security, then Core Isolation Details
  • Toggle Memory Integrity to Off
  • Open Command Prompt as Administrator and run: bcdedit /set hypervisorlaunchtype off
  • Press Win + R, type optionalfeatures, and uncheck Hyper-V and related features
  • Restart your PC and relaunch Forza Horizon 6

Conclusion

The Forza Horizon 6 FHE01, FHC01, and FHD01 errors combined with Out of Video Memory and video card crashes form a layered GPU resource failure that requires addressing VRAM usage, driver integrity, thermal management, and Gaming Services simultaneously. Start with Fix 1 and Fix 2 for the fastest results across all three error codes. Work through the remaining fixes if any individual error code persists. With reduced graphics settings, clean GPU drivers, stock clock speeds, and repaired Gaming Services, all three error codes will stop appearing and Forza Horizon 6 will run without GPU resource failures.
