Is the driver available here,
https://www.dell.com/support/home/us/en/19/Drivers/DriversDetails?driverid=33X2V
compatible with Windows 8.1 64-bit?
Because the description says (emphasis mine),
"This package provides the driver for Intel HD Graphics and is supported on XPS 9343 running the following Windows operating systems:Windows 8.1-bit; Windows 10 64-bit."
What exactly does "Window 8.1-bit" mean?
