shared gpu memory

Shared GPU memory refers to a portion of system RAM that the operating system allocates for use by the integrated or discrete GPU when its dedicated video memory is exhausted. On Windows 11 24H2, Intel's August 2025 GPU driver update introduces a new "Shared GPU Memory Override" toggle, giving users granular control over how much system memory is reserved for graphics tasks. This feature is particularly relevant for Intel Arc and integrated GPUs, allowing enthusiasts to fine-tune performance and balance memory allocation between the GPU and other applications. The update also brings performance boosts of up to 5% in certain workloads, making shared GPU memory management a key aspect of optimizing Windows 11 for gaming and creative work.
