Resizable BAR is RTX 3060 and mobile GPUs only for now, with other Ampere desktop GPUs to follow

Nvidia has introduced support for resizable BAR, which delivers a nice frame rate boost in some games, with its just-launched

GeForce RTX 3060 graphics card

. Other desktop GPUs will get the feature late in March, Nvidia notes, although RTX 30 series laptop graphics cards will benefit from it off the bat.

If this feature rings a bell, it’s because PCIe’s resizable BAR capability first came to light when AMD introduced it with the launch of

Big Navi graphics cards

, in the form of

Smart Access Memory

(SAM).

Intel and Nvidia were then quick to jump on the bandwagon and point out that they would be bringing in support for this feature too, with

Nvidia making it clear that faster frame rates

would be coming to RTX 3000 series graphics cards back in November 2020.

So, that support is now live for

RTX 3060

owners, providing they’re running an AMD Ryzen 5000 CPU (with 500 series or 400 series motherboard), or on the Intel front, a 10th-gen Comet Lake CPU (or one of the incoming Rocket Lake processors, when they’re out).

In the case of laptops, the requirements are an RTX 30 series GPU and 11th-gen Tiger Lake mobile chip or Ryzen 5000 CPU. For the full list of compatible chips and motherboards, see

Nvidia’s blog post

.

Naturally, as well as compatible hardware, you’ll need the relevant motherboard and graphics card BIOS updates – although in the latter case, the RTX 3060 ships with the correct BIOS – as well as Nvidia’s latest Game Ready driver.

BAR benefits – or not

In simple terms, resizable BAR works by lifting memory constraints on CPU to GPU data access, which gives a decent performance uplift, although Nvidia is somewhat cautious on exactly what it will achieve.

As the GPU maker explains, the performance increase you can expect varies quite widely depending on the exact game. Nvidia notes: “In our testing, we’ve found some titles benefit from a few percent, up to 10% [frame rate increases]. However, there are also titles that see a decrease in performance.”

That being the case, Nvidia is running tests on games and will only enable resizable BAR if it makes sense, or in other words, if any given game gets a frame rate boost from the feature. There’s no use running it with a game if it’s proving a hindrance, of course.

These are the titles which are initially supported by the feature as of now:

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

Nvidia says that more games will be opened up for support when it provides the driver update late in March which will bring resizable BAR to the rest of the RTX 3000 range of desktop GPUs.
