How to Fix Cairn Crashing on Startup, Black Screen & Stuttering

You have waited months for Cairn, pre-loaded the files, and cleared your schedule to guide Aava up the most unforgiving peaks. You click “Play,” and… nothing. Or worse, a cryptic “Fatal Error” pops up. Launch day issues are frustrating, especially when you’re itching to test the game’s realistic climbing physics, but they are rarely unfixable.

Whether you are facing a black screen, random crashes to desktop (CTD), missing DLL files, or unplayable frame rates that turn your smooth ascent into a slideshow, this guide covers the most effective solutions to get you into the game.

Editor’s View: The “Day One” Curse

Check First: Cairn System Requirements

Method 1: Verify Game Files (Steam/Epic)

Corrupted installation files are the #1 cause of Cairn crashing on startup.

• Steam: Right-click Cairn > Properties > Installed Files > Verify integrity of game files.
• Epic: Click the three dots on the game card > Manage > Verify.

Method 2: Update Drivers & C++ Redistributables

Cairn runs on a modern engine that strictly requires updated software environments.

• GPU Drivers: Update your NVIDIA (Game Ready) or AMD (Adrenalin) drivers.
• Visual C++ All-in-One: If you get MSVCP140.dll missing errors, reinstall the Microsoft Visual C++ Redistributables (x86 and x64).

Method 3: Fix Black Screen & Overlay Issues

If you encounter a black screen on launch, overlays might be the culprit. Disable Steam Overlay, Discord Overlay, and any FPS counters to resolve conflicts.

Method 4: Fix Shader Compilation & CPU Instability (UE5)

Cairn uses Unreal Engine 5, which compiles shaders on launch. If it crashes at 0% progress:

Method 5: Offload PhysX Simulation to GPU

Cairn’s procedural climbing is physics-heavy. If the game crashes when Aava touches the wall:

Method 6: Common Error Codes & Fixes (DLL / DX12)

• Error 0xc0000005: Add Cairn to your Antivirus/Windows Defender “Exclusions” list.
• “Out of Video Memory”: Lower your Texture Quality to Medium and restart.
• “DX12 not supported”: Force DirectX 11 by adding -dx11 to your Steam Launch Options.

Method 7: Fix Low FPS & Stuttering

If the game is running, but performance is poor, try disabling V-Sync and lowering Global Illumination settings.

How to Fix Cairn Stuck on Loading Screen (SSD Required)

If you are stuck on the mountain loading screen:

• Fix A: Clear the AppData\Local\Cairn\Saved\Shaders folder to reset the cache.
• Fix B: Move the game to an SSD. Cairn uses high-speed asset streaming; HDDs will cause the engine to time out and hang during level transitions.

The Workaround: Skip Buggy Sequences with XMODhub

If Cairn keeps crashing during a specific scripted climb or physics-heavy cutscene, XMODhub can help you bypass the bottleneck:

• Speedhack: Slow down the game to 0.5x to give your CPU more time to process physics frames during heavy sequences to prevent crashes.
• Save Manager: Automatically backup your save before entering “crash-prone” zones like the higher peaks of Mount Kami.
