Generic game-reported DirectX crash

What is DIRECTX-FUNCTION-ERROR?

DirectX Function Error shows up as a high-severity graphics API (DirectX) fault. A generic crash occurred inside the graphics engine API loop, reporting a failure from a DirectX function call. This usually traces back to unstable GPU overclocking or power draw and corrupt game files or shader cache. Use the steps below to track down and fix the cause.

Common Causes

• Outdated or corrupted graphics driver
• Unstable GPU overclocking or power draw
• Corrupt game files or shader cache

Step-by-Step Fix Guide

• 1
  Perform a clean GPU driver reinstall using DDU

  The highest-success first step is Perform a clean GPU driver reinstall using DDU, which targets the most common trigger behind DirectX Function Error.

• 2
  Disable overlays and reset overclocks

  A second occurrence often means a less common directx instability cause is at play, which later steps address.

• 3
  Verify game file integrity and clear shader cache

  "Verify game file integrity and clear shader cache" targets corrupt game files or shader cache, one of the documented causes of DIRECTX-FUNCTION-ERROR.
