LowLevelFatalError [File:Unknown] [Line: 686] DXGI_ERROR_DEVICE_HUNG

I think I have found a possibile solution deleting the GPU cache.

Go to C:\Users\<user>\AppData\Local\NVIDIA\DXCache and delete all the files inside the folder.

Some files cannot be deleted and it is ok, just delete all the files you can.

This solution is not permanenet. When the error pop ups again, repeat this process.

For AMD GPU I don't know where the cache is.
