What Is Resizable BAR

Resizable BAR is an optional PCI Express interface technology. As you move through a world in a game, GPU memory (VRAM) constantly transfers textures, shaders and geometry via many small CPU to GPU transfers, using Resizable BAR- assets can instead be requested as-needed and sent in full, so the CPU can efficiently access the entire frame buffer and if multiple requests are made, transfers can occur concurrently, rather than queuing.

GeForce RTX 30 Series laptops with Resizable BAR-capable Intel and AMD CPUs are available now. Check with each laptop manufacturer to discover if Resizable BAR is supported on a particular model.

For desktops, you will need a compatible CPU, compatible motherboard, motherboard SBIOS update, GPU VBIOS update (the GeForce RTX 3060 already ships with the necessary BIOS) and a new GeForce Game Ready driver to enable Resizable BAR.
