Fix COD / Warzone DEV ERROR 6068 (DirectX crash)
Warzone crashes to desktop with a red DEV ERROR 6068 box — sometimes mid-match, sometimes at the loading screen. It's a DirectX/VRAM failure code, and it's the single most-reported crash in the current COD engine. The cause is almost always unstable video memory: an overclock, a corrupt shader cache, or VRAM pressure.
DirectX encountered an unrecoverable error.
Why this happens
DEV ERROR 6068 means the game's DirectX context was lost — the GPU stopped responding. The three triggers, in order of frequency: GPU overclocks / memory overclocks (including XMP profiles), corrupt shader caches, and VRAM pressure from texture settings exceeding your card's memory.
Fixes, in order
If you use MSI Afterburner / EVGA Precision / AMD Adrenalin tuning: set core clock, memory clock and power limit back to defaults, restart the game and test. 6068 is famous for being caused by a +50 MHz memory overclock that passes stress tests but dies under COD's VRAM load.
- Press Win+R, paste: %ProgramData%\NVIDIA Corporation\NV_Cache (NVIDIA) or C:\Program Files\AMD\CNext\CNextCache (AMD)
- Delete the contents, then run Disk Cleanup → DirectX Shader Cache
- In COD: Settings → Graphics → Restart Shaders Optimization (let it finish before playing)
In COD graphics settings, set Texture Resolution to one step below your VRAM comfort zone (8 GB card → "Normal/Medium"), disable On-Demand Texture Streaming if you have it on, and cap your frame rate to your monitor's refresh. The game's VRAM usage bar should sit at ~80% or less.
Download the latest driver and choose Custom → Clean installation (NVIDIA) or Factory Reset (AMD). COD engines accumulate driver-level corruption across updates; a clean install removes it.
GeForce Experience overlay, Discord overlay, and Xbox Game Bar recording have all been reported to trigger 6068 in busy matches. Turn them off, test for an hour.
