When SDI considers a driver to be optimal, does mean that the driver matches full hardware ID of a device? So for example it will be a driver provided by the PC manufacturer, rather than the standard driver provided my the device manufacturer? When SDI finds a more optimal driver for device, I'm aware that Microsoft drivers will be considered less than optimal and therefore SDI will often find more optimal drivers for them. Is the same true for devices which has the standard driver provided by the device manufacturer installed and there is a driver available which has been customised by the PC manufacturer?
Is it possible to get an answer?
yes it must match the hardware id of the device.
@glenn By hardware ID, do you mean the long hardware ID, as detailed here?

I don't have the details handy. However, the product is open source and so you are free to examine the source code and make your own judgment.
