What Is the fhc01 Error?
The fhc01 error occurs when Forza Horizon 6's ForzaTech engine cannot properly recognize or initialize your GPU's DX12 rendering pipeline. This typically happens when:
- Your GPU drivers are outdated (especially common on AMD cards pre-26.5.2)
- Windows is routing the game to your integrated graphics instead of your dedicated GPU
- The game's fullscreen rendering mode conflicts with your display configuration
Step-by-Step Fix
- Update GPU Drivers: Download and install the latest drivers for your graphics card:
- AMD: Version 26.5.2 or higher — this is the minimum certified driver for FH6
- NVIDIA: Latest Game Ready driver from GeForce Experience
- Disable Integrated Graphics: Press Win + X → Device Manager → expand Display adapters. Right-click your integrated GPU (e.g., Intel UHD Graphics, AMD Radeon Graphics) and select "Disable device". Your dedicated GPU will now handle all rendering.
- Disable Fullscreen Optimizations: Locate
FH6.exe(Steam: right-click FH6 → Manage → Browse local files). Right-clickFH6.exe→ Properties → Compatibility tab → check "Disable fullscreen optimizations" → Apply. - Override Graphics Adapter: In Windows Settings → System → Display → Graphics, find Forza Horizon 6, click Options, and set it to "High performance" (your dedicated GPU).
Why Driver 26.5.2+?
AMD driver 26.5.2 includes critical DX12 rendering pipeline fixes specifically for Forza Horizon 6. Earlier driver versions lack these fixes, causing the fhc01 error even on otherwise compatible GPUs like the RX 9070 XT.
Still Getting the Error?
If the fhc01 error persists after trying all steps above:
- Run a clean install of your GPU drivers using DDU (Display Driver Uninstaller) in Safe Mode
- Verify FH6 game files via Steam (right-click → Properties → Installed Files → Verify integrity)
- Check that your dedicated GPU meets the minimum requirements (NVIDIA GTX 1060 / AMD RX 580 or better)
- Temporarily disable any GPU overclocking software (MSI Afterburner, etc.)
Secure Boot & TPM 2.0 — Not Required
Despite community rumors, Secure Boot and TPM 2.0 are NOT required to run Forza Horizon 6 on PC. These are only needed for Windows 11 installation, not for game compatibility. Do not change your BIOS settings trying to fix this error.
