Posted on
The NVIDIA App is preparing Auto, Enabled, and Disabled controls for Resizable BAR, making per-game overrides easier to manage.

Quick Report

NVIDIA is preparing to add Resizable BAR controls to the NVIDIA App, with Auto, Enabled, and Disabled options. Auto will follow the driver profile, while the other modes will let users override the setting for individual games without relying on BIOS changes or third-party profile tools.

Resizable BAR allows the CPU to access the graphics card memory in larger transfers instead of 256 MB chunks, though performance gains are usually limited to low single-digit percentages. The feature requires compatible hardware, UEFI boot with CSM disabled, and support from the motherboard and graphics card; NVIDIA has not yet confirmed the exact app release, but the option is expected with an upcoming Game Ready driver.
