The crash reporter pops up. Or the game<\/a> hangs at a black screen. Or you get that dreaded \u201clow-level fatal error\u201d right after the shader compilation bar finishes. Most players jump straight to GPU driver reinstallation or verifying game files. That\u2019s not wrong, but it skips the root cause: corrupted shader cache. Star Wars<\/a> Zero Company<\/strong> builds a shader cache on first launch. If that cache becomes corrupt\u2014and it does, often\u2014the game will crash repeatedly until you wipe it clean. Here\u2019s exactly how to do that with Windows<\/a> Disk Cleanup, and why the standard advice misses a few critical details.<\/p>\n

Why Shader Cache Corruption Causes Crashes<\/h2>\n

Shader compilation translates high-level graphics instructions into GPU-specific machine code. Modern games like Star Wars Zero Company<\/strong> compile shaders once and cache the result to avoid stutter on subsequent launches. But the cache is stored on disk as binary files. Disk writes can be interrupted by a power loss, a driver crash, or even a game update that changes the compiled shaders. The result: a corrupted file that the game tries to load, fails, and then throws a crash reporter error.<\/p>\n

The crash often looks like a GPU driver issue\u2014the error message may say \u201cGPU crash dump triggered.\u201d That\u2019s because the graphics driver is the first layer to detect the invalid data. But reinstalling the driver won\u2019t fix a bad cache file. You have to clear it first.<\/p>\n

Windows Disk Cleanup: The Standard Method (and Its Quirk)<\/h2>\n

The recommended approach from most troubleshooting guides is straightforward:<\/p>\n

    \n
  1. Open Windows Disk Cleanup (search for it in the Start menu).<\/li>\n
  2. Select the drive where your Windows installation lives (usually C:).<\/li>\n
  3. Click \u201cClean up system files\u201d (this gives you access to additional categories).<\/li>\n
  4. Scroll down the list and check \u201cDirectX Shader Cache.\u201d<\/li>\n
  5. Click OK, confirm, wait for the cleanup to finish.<\/li>\n
  6. Restart your PC. Then launch the game.<\/li>\n<\/ol>\n

    That works. But there\u2019s a nuance the guides don\u2019t tell you: Disk Cleanup only clears the DirectX shader cache, not other types.<\/strong> Vulkan shader caches, for instance, live in different folders. Star Wars Zero Company<\/strong> runs on Unreal Engine<\/a> 5, which uses DirectX 12 by default. So Disk Cleanup is the right too. But if you\u2019ve ever forced the game to run on Vulcan (via launch options like - vulkan<\/code>codecodecodecodecodecode) or if you\u2019re using an AMD GPU that caches shaders separately, you need to go deeper.<\/p>\n

    When Disk Cleanup Isn\u2019t Enough<\/h3>\n

    I\u2019ve seen cases where clearing the DirectX cache via Disk Cleanup did nothing. Here are the reasons why, and what to do:<\/p>\n
