Vulkan VK_ERROR_DEVICE_LOST
What is this error?
The Vulkan graphics device was lost during rendering. The GPU driver crashed or stopped responding while the game was using Vulkan API.
Common causes
- GPU driver crash
- GPU overclock instability
- driver doesn't fully support Vulkan features the game uses
- GPU overheating
- VRAM exhaustion
How to fix it
- Update GPU driver
- disable GPU overclock
- lower Vulkan-specific settings
- switch to DirectX if available

VK_ERROR_DEVICE_LOST (-4) is the Vulkan equivalent of DirectX's DXGI_ERROR_DEVICE_REMOVED — your GPU crashed while running a Vulkan game. Games like Baldur's Gate 3, Doom Eternal, Red Dead Redemption 2, and many Steam Deck ports use Vulkan.
How to fix it:
- Update your GPU driver to the latest version — Vulkan support improves significantly with each driver release
- If using NVIDIA, try the Vulkan Beta driver from NVIDIA's developer site — it often has newer Vulkan fixes than Game Ready drivers
- Disable any GPU overclock — Vulkan games stress the GPU differently than DirectX
- Lower graphics settings, especially ray tracing and high VRAM options
- If the game offers both Vulkan and DirectX, try switching to DirectX 11 or 12
- Check GPU temperatures — overheating causes Vulkan device loss
- Increase TDR timeout: Registry Editor > HKLM\SYSTEM\CurrentControlSet\Control\GraphicsDrivers > DWORD 'TdrDelay' = 10
- On AMD GPUs, disable Radeon Anti-Lag — it conflicts with some Vulkan games
When to seek help
If this error keeps happening after trying the fixes above, it may point to a deeper hardware or system issue. Consider professional help if:
- The crash occurs across multiple games or applications
- You see the same error after a clean Windows install
- Your PC is less than a year old (could be a warranty issue)
- You smell burning or hear unusual sounds from your PC
