Beta and driver
#1
Windows 10.0.18363.900 Pro x64, MSI GTX 1080 Ti 11G, nVidia driver 446.14:

Code:
hashcat (v5.1.0-1803-g1dc3469f) starting...

* Device #1: CUDA SDK Toolkit installation NOT detected.
            CUDA SDK Toolkit installation required for proper device support and utilization
            Falling back to OpenCL Runtime

* Device #1: Outdated or broken NVIDIA driver '446.14' detected!

You are STRONGLY encouraged to use the officially supported NVIDIA driver.
See hashcat's homepage for officially supported NVIDIA drivers.

You can use --force to override this, but do not report related errors.

Earlier I installed CUDA Toolkit from Intel, removed (graphic card not visible by hashcat) by DDU, reinstalled nVidia driver (visible by hashcat), installed CUDA Toolkit from nVidia (similar error), removed all nVidia related to CUDA (this error) and reinstalled graphic driver (this error).

Why beta is not seeing proper driver?
