Earlier this month, Intel released Arc Graphics 32.0.101.6987 driver, its latest WHQL version driver. The driver this time also supports the shared video memory overlay control function for the built-in sharp graphics cards of some Intel Core Ultra 100/200 series processors, and is suitable for Windows 10/11 operating systems.
According to TomsHardware, since the built-in sharp graphics card in Intel processors uses system memory to store work data, it is not equipped with a separate video memory like a discrete graphics card. The maximum capacity of the average user's PC for integrated graphics is half of the system memory, but Intel's new tool can exceed this limit.
Under default settings, the upper limit provided by the shared memory overlay control function is 57%, and users can also manually adjust it through Intel Graphics Software. The upper limit that can be set depends on how much system memory the user's PC has. The larger the capacity, the higher the percentage. Officially, it can reach 87%. According to Intel, the shared memory overlay control feature requires at least 10GB of system memory and a Core Ultra 200 series or higher processor (this is different from the Core Ultra 100 series covered in the release notes).
This kind of control is not the first of its kind for Intel. It is more common on AMD platforms, and the graphics memory allocation can be changed through BIOS-level settings (usually limited to about 8GB). The new feature gives users greater control, but over-allocation can lead to unreasonable situations where the processor lacks enough system memory, especially in workloads such as multitasking. If it is a laptop computer, improper settings to allow the memory to run for a long time may even lead to increased power consumption.
