Your game launcher loads fine. Then the frame drops hit. CPU usage shoots to 100% and stays there. Seconds later the crash reporter appears \u2014 “low-level fatal error” or “GPU crash dump triggered”. You’re not alone. Thousands of players face this exact pattern.<\/p>\n\n
The common assumption? The game<\/a> is badly optimized and hogging CPU cycles. That’s only half right. The real culprit is something more specific: aggressive real-time shader compilation that overwhelms the processor, combined with a corrupt shader cache that turns a heavy load into a crash. The fixes are known but rarely presented in the right order. This guide gives you the sequence that actually stops the crashes.<\/p>\n\n Star Wars<\/a> Zero Company<\/strong> runs on Unreal Engine<\/a>. Modern Unreal titles compile shaders when you first launch. But this game does something different \u2014 it recompiles shaders during gameplay, not just at startup. Every time a new effect, particle, or lighting scenario appears, the CPU gets hit with a batch of compilation tasks. On a clean install that process is manageable. With a corrupted cache? The same shader gets compiled repeatedy, loops, and eats every core.<\/p>\n\n The crash reporter shows up because one of these threads times out or overruns available memory. The “low-level fatal error” is the engine throwing its hands up when a shader fails to compile during an active frame.<\/p>\n\n A corrupted DirectX Shader Cache is the single most common cause. Windows stores this cache in That’s also why clearing that cache fixes the problem for most people. The first launch after clearing it takes longer \u2014 the shaders have to be rebuilt from scratch<\/a> \u2014 but the process is clean and the crashes stop.<\/p>\n\n Most guides throw 15 steps at you. That overlooks something critical: the order matters. Here’s the sequence that resolves the 100% CPU crash for the majority of players.<\/p>\n\n Open Windows Disk Cleanup ( Do this before anything else. Updating drivers or verifying game files while a corrupt shader cache exists is like swapping tires on a car with a blown engine \u2014 the root issue remains.<\/p>\n\n After the cache clears, restart your PC. Then launch the game. The first load will take 2\u20133 minutes longer. That is normal. Do not interrupt it. Let the shaders rebuild fully.<\/p>\n\n Star Wars Zero Company<\/strong> is memory-hungry during compilation. If your paging file is too small \u2014 Windows sets it automatically, often at just 1\u20132 GB \u2014 the game runs out of virtual address space during heavy shader loads.<\/p>\n\n Search for “Advanced system settings”. Under Performance \u2192 Advanced \u2192 Virtual memory, change the paging file to “Custom size”. Set initial and maximum size to 16 GB<\/strong> (16384 MB). Apply and restart.<\/p>\n\n A 16 GB paging file is not excessive. The game will use what it needs. On 8 GB RAM systems, this step alone stops the crash reporter from appearing.<\/p>\n\n Nvidia, AMD, and Intel all released drivers specifically targeting Star Wars Zero Company<\/strong> performance. Use Nvidia’s 537.58 or later, AMD’s 23.11.1 or later.<\/p>\n\n Do not just update via Windows Device Manager \u2014 that often installs generic drivers. Go to the manufacturer’s site, download the full installer, and run it. Select “Clean Installation” if available (Nvidia) or “Factory Reset” (AMD). This clears any remnants of previous drivers that could conflict with the game’s compilation calls.<\/p>\n\nWhy Star Wars Zero Company Pegs the CPU at 100%<\/h2>
%AppData%\\Local\\Temp\\DXCache<\/code>codecodecodecodecodecode and related folders. When files there get corrupted \u2014 often from a crash mid-compilation \u2014 the engine retrys and retrys, driving CPU to 100% until it crashes again.<\/p>\n\nThe Fixes That Actually Work: A Sequence, Not a Scatler Gun<\/h2>
Step 1: Clear the Shader Cache First<\/h3>
cleanmgr.exe<\/code>codecodecodecodecodecode). Select the drive where Windows is installed. Scroll down and check “DirectX Shader Cache”. Hit OK. This clears the cached files that are likely corrupted.<\/p>\n\nStep 2: Increase Virtual Memory<\/h3>
Step 3: Update GPU Drivers \u2014 But Do It Cleanly<\/h3>
Step 4: Disable All Overlays<\/h3>
