### Debugging
The following environment variables can be used for **debugging** purposes.
- `VK_INSTANCE_LAYERS=VK_LAYER_LUNARG_standard_validation` Enables Vulkan debug layers. Highly recommended for troubleshooting rendering issues and driver crashes. Requires the Vulkan SDK to be installed on the host system.
- `DXVK_CUSTOM_VENDOR_ID=<ID>` Specifies a custom PCI vendor ID
- `DXVK_CUSTOM_DEVICE_ID=<ID>` Specifies a custom PCI device ID
- `DXVK_LOG_LEVEL=none|error|warn|info|debug` Controls message logging
## Troubleshooting
