Nvidia’s resizable BAR frame rate boosts are now available on all 30 Series GPUs


Nvidia is launching support for Resizable Bars today, a feature of PCI Express that can increase the frame rate in some games by up to 10%. Resizable BAR works by unlocking access to the full graphics image buffer, instead of limiting it to 256MB of block read. This may improve frame rates in games, but it will require a compatible processor, a motherboard BIOS update, and even a VBIOS update for all 30-series desktop GPUs.

Nvidia has worked with AMD and Intel to provide support for chipsets. AMD’s Zen 3 processors are supported, alongside Intel’s 10th generation processors and the company’s new 11th generation desktop chips released today. You can find Nvidia’s full motherboard FAQs and VBIOS updates here.

Resizable BAR works the same as AMD’s Smart Access memory, which also promises to improve frame rates in some games by up to 10%. Increasing the frame rate using both will really depend on the game and the resolution will have an impact on improving performance as well.

The new RTX 3060 graphics card was the first to include Resizable BAR last month, and wccftech found it to improve performance by 4-11% in some games. Nvidia initially limited support to less than 10 games, as the company warned that activating it on all games could cause performance to drop in some.

Nvidia now pre-tests titles and uses special game profiles to activate the resizable bar only where performance increases. This means that only 17 games are currently supported, of which Cyberpunk 2077, Assassin’s Creed Valhalla, and Watch Dogs Legion. More games will be added in future driver updates.

The resizable AMD side BAR support has been extensively tested, and TechSpot found that some games using Smart Access memory could experience an increase of almost 20% at 1440p and 4K.
