public static int graphicsDeviceID;
Description
The identifier code of the graphics device (Read Only).
This is the PCI device ID of the user's graphics card. Together with SystemInfo.graphicsDeviceVendorID, this number uniquely identifies a particular graphics card model. The number is the same across operating systems and driver versions.
Note that device IDs are only implemented on PC (Windows/Mac/Linux) platforms and on Android when running Vulkan; on other platforms you'll have to do name-based detection if needed.
See pci-ids.ucw.cz for a list of device IDs.
