On the next-to-last day of the month, Team Green delivered. The newly available Game Ready driver version 456.89 unlocks Resizable BAR on every RTX 30-series desktop graphics cards.

It’s not quite that easy though. While the new drivers activate Resizable BAR, you’ll also need to wait for a new VBIOS from your graphics card’s specific manufacturer to add support for your particular model.
