Nvidia begins to increase frame rate by up to 10% on 30 series GPUs



Nvidia has begun to support Resizable BAR, a feature of PCI Express that can increase the frame rate of some games by up to 10%. The new RTX 3060 graphics card is the first to include a resizable BAR, which allows certain CPUs to access the complete graphics frame buffer, rather than being limited to reading 256MB blocks. Other 30 series GPUs will be supported in late March.

You need the right CPU, motherboard, and graphics card to use this new feature, and Nvidia is working with AMD and Intel to provide chipset support. It supports AMD’s Zen 3 CPU, as well as Intel’s 10th-generation processors and the company’s upcoming 1

1th-generation S chips.

Just like AMD’s Smart Access Memory, the resizable BAR on the Nvidia GPU can increase the frame rate of certain games by up to 10%. The improvement really depends on the game, and the resolution may also affect the performance improvement. Nvidia said: “In our tests, we found that certain games can benefit from a few percent to 10 percent of revenue.” “However, the performance of some titles will also decline.”

Nvidia is pre-testing the game and using a special game profile to enable Resizable BAR only when performance is improved. The following games are currently supported:

  • Assassin’s Creed Valhalla
  • Battlefield 5
  • Borderlands 3
  • Forza Motorsport: Horizon 4
  • Gear 5
  • Metro Exodus
  • Red Dead Redemption 2
  • Watchdog: Legion

In late March, Nvidia will support other games when it launches a VIOS update for its remaining 30-series GPUs. Nvidia will provide VBIOS updates for all Founders Edition 30 series cards, and board partners will also release their own updates. You also need a motherboard update, which includes the necessary CPU support. Nvidia said that Asus, ASRock, Colorful, Evga, Gigabyte and MSI have begun to support Resizable BAR on some motherboards.

AMD’s resizable BAR support has been extensively tested, and TechSpot It is found that some games using Smart Access Memory may increase by nearly 20% at 1440p and 4K resolution.
