When launching the new GeForce RTX 30 series desktop graphics cards, NVIDIA announced that it would introduce Resizable BAR, a PCIe-based technology that would allow users with a compatible motherboard to allow access to all memory. of the GPU by the CPU at a time. Similar to AMD’s Smart Access memory, this meant faster transfer of data, including textures, shaders, and geometry, providing roughly 10-20% gains while playing.

The technology was initially activated in February 2021 when NVIDIA started shipping the GeForce RTX 3060, its most affordable option in the series. Now, the company has officially enabled support for all RTX 30 series, which include the RTX 3090, RTX 3080, RTX 3070, and RTX 3060 Ti. Besides a supported motherboard, NVIDIA has also shared a list of processors that will support Resizable BAR, so unless you have the right combination of GPU, CPU, and motherboard, you can’t take advantage of this technology. .

Additionally, only a handful of games can use Resizable BAR, including:

  • Assassin’s Creed Valhalla
  • Battlefield v
  • Borderlands 3
  • Control
  • Cyberpunk 2077
  • Death Stranding
  • DIRT 5
  • F1 2020
  • Forza Horizon 4
  • Gears 5
  • Godfall
  • Hitman 2
  • Hitman 3
  • Horizon Zero Dawn
  • Metro Exodus
  • Red Dead Redemption 2
  • Watch Dogs Legion
