Intel's new graphics driver lets you dedicate up to 87% of laptop memory capacity to the iGPU for VRAM — Core Ultra CPUs get "Shared GPU Memory Override" feature

Intel Arc Battlemage B580 and B570.

Intel’s Arc graphics driver version 32.0.101.6987 introduces a first for the company’s integrated GPUs: manual control over system memory allocation for graphics workloads. "Intel Graphics Software now supports Shared GPU Memory Override control for Built-in Intel Arc GPUs in select Intel Core Ultra Processors (series 1 and 2) in Windows 10 and Windows 11 host systems," the release notes state.

Intel's integrated GPUs use system memory to store working data, rather than a separate GDDR memory pool for graphics and video applications like a discrete GPU does. The maximum amount of memory your computer can use is generally limited to one-half of the system memory, but Intel's new tool lets users override this.
