Nvidia has started rolling out support for the Resizable Bar, a feature of PCI Express, which can increase the frame rate to 10 percent in some games. The new RTX 3060 graphics card first incorporates the Resignable Bar, which allows some CPUs to access the full graphics frame buffer instead of being limited to only 256 MB blocks. Support for other 30-series GPUs will be available in late March.
You’ll need the right CPU, motherboard, and graphics card to use this new feature, and Nvidia is working with both AMD and Intel to provide chipset support. AMD’s 400 and 500 Series CPUs are supported with Intel’s 10th Gen processor and the company’s upcoming 11th Gen S chips.
AMD’s smart access memory, resolvable times on Nvidia GPUs, can increase the frame rate by up to 10 percent in some games. The boost is really dependent on the game, and the resolution can also affect how much the performance will increase. “In our testing, we’ve found that some titles benefit from a few percent to 10 percent,” Nvidia says. “However, there are also titles that see a decrease in performance.”
Nvidia is a pre-testing title and uses special game profiles to enable the resolution BAR where performance increases. The following games are currently supported:
- Assassin breed
- Battlefield V
- Border 3
- Forza Horizon 4
- 5
- Metro Exodus
- Red dead redemption 2
- Watch Dogs: Army
Additional games will be supported in late March, when Nvidia launches the VIOS update for its 30-series GPU. Nvidia will supply VBIOS updates for all Founders Edition 30-Series cards, and board partners will also release their own updates. You’ll also need a motherboard update that includes the necessary CPU support, and Nvidia says that Asus, Asrock, Color, Evga, Gigabyte, and MSI have all started supporting Resizable BAR on select motherboards.
Qualitative BAR support has been widely tested by AMD, and Techspot found it Some games that use smart access memory can see an increase of around 20 percent at 1440p and 4K.
