Resizable BAR is now available for NVIDIA's full RTX 30 desktop product stack, as the company promised earlier this month. Resizable BAR is available for most modern AMD and Intel chipsets and processors, including Zen 3 and Comet Lake-S CPUs. NVIDIA has expandable Resizable BAR support to 17 games, too.

NVIDIA has delivered on its promise to bring Resizable BAR to its RTX 30 series desktop cards by the end of March. Currently, NVIDIA has enabled Resizable BAR for seventeen games, up from eight at the start of this month. The seventeen games are as follows:

  • 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

NVIDIA states that it will continue to expand Resizable BAR support via Game Ready Driver updates. You must install a VBIOS update on your RTX 30 series desktop card to enable Resizable BAR, too. NVIDIA has provided download links where possible for board-partner cards and has published a knowledge base article for its Founders Edition models. For motherboard and processor compatibility details, please see NVIDIA's corresponding press release.

You can verify if Resizable BAR is working by heading to the NVIDIA Control Panel. Once there, bring up 'System Information', which will confirm if Resizable BAR is working.

According to initial benchmarks on Chiphell, Resizable BAR yields a 3% performance improvement for high-end Ampere cards like the RTX 3090. By contrast, NVIDIA claims that Resizable BAR can generate over 5.9% higher framerates in at least five games when used on the RTX 3080 at 1440p. Either way, we expect NVIDIA to refine Resizable BAR over time.
