Nvidia starts increasing frame rates by up to 10 percent on 30 series GPUs

Nvidia has begun rolling out support for RESizable BAR, a PCI Express feature that can increase frame rates in certain games by up to 10 percent. The new RTX 3060 video card is the first to include a resizable BAR, which allows certain CPUs to access the full graphics frame buffer, rather than just reading 256 MB blocks. Support for other 30 series GPUs will be available in late March.

You will need the right CPU, motherboard and video card to use this new feature, and Nvidia is working with AMD and Intel to provide chipset support. AMD’s Zen 3 CPUs are supported, along with the company’s 10th generation Intel processors and the company’s next 11th Generation S chips.

Much like AMD’s intelligent access memory, the scalable BAR on Nvidia GPUs can increase frame rates in certain games by up to 10 percent. The increase really depends on the game and the resolution can also affect how much the performance will increase. “In our tests, we found that some titles benefit from a small percentage, up to 10%,” says Nvidia. “However, there are also titles that show a drop in performance.”

Nvidia is pre-testing the titles and using special game profiles to enable the resizable BAR only where performance increases. The following games are currently supported:

  • Assassin’s Creed Valhalla
  • Battlefield V
  • Borderlands 3
  • Forza Horizon 4
  • Gears 5
  • Metro Exodus
  • Red Dead Redemption 2
  • Watch Dogs: Legion

Additional games will be supported in late March, when Nvidia releases VIOS updates for the rest of its 30 series GPUs. Nvidia will provide VBIOS updates for all Founders Edition 30 series cards, and card partners will also launch their own. updates. You will also need a motherboard update that includes the necessary CPU support, and Nvidia says Asus, Asrock, Colorful, Evga, Gigabyte and MSI have started to support resizable BAR on select motherboards.

The scalable BAR support on the AMD side has been extensively tested and TechSpot found that some games that use Smart Access Memory can have an increase of almost 20% in 1440p and 4K.
