Nvidia Resizable BAR support is now ready, boosting frames per second for RTX 30 Series


The only thing gamers can’t get enough of is the frame rate. The preference is well established as well, as an issue of performance can either lead to or end an immersive experience. With that, modern generations of graphics hardware are constantly improving. Nvidia’s range of RTX graphics cards offer revolutionary features like DLSS to provide frame rate enhancements without (in theory) quality. AMD changed the game again when it introduced Smart Access Memory (SAM). This feature is actually just a scalable bar, which allows GPU memory and CPU to work more efficiently together to optimize data transfers. Nvidia initially had no response to SAM, but that is changing today.

If you are one of the lucky few who owns an RTX 30 series laptop or an RTX 3060 desktop graphics card (with supporting devices), you can reap the benefits of roughly 10% better gaming performance in a select number of games today. Free fps is great, but the feature really looks a bit decent, right? Don’t worry, more support is coming in March. The resizable BAR feature will also become a standard feature for New generations of devices. It definitely deserves a thrill.

We talked about a variable size tape In more detail In other articles, but what’s important is that it allows your system to function better by taking advantage of the previously unused PCIe 3.0 feature. That’s why you’ll learn that it’s partially backward compatible, depending on CPU and motherboard.

Does your system support that?

Ultimately, the entire Nvidia RTX 30 Series will support Resizable BAR. You will be able to pair one of these cards with either an AMD Ryzen 5000 series or an 11th generation Intel CPU to enable the feature. 10th generation Intel CPUs will also work, but this should apply pretty much every 10th generation CPU that gamers use. For AMD, there’s no word on backward compatibility of the CPU, and I’m not going to rely on it.

Compatibility with Nvidia Resizable Tape

Aside from the CPU, you’ll also need to verify that the motherboard is able to support the Resizable BAR. Just like with the 11th generation Intel processors, the 11th generation chipset will be ready to go. Intel also ensures that the 10th generation motherboards Z490, H470, B460, and H410 will work. However, you will have to do the SBIOS update on the motherboard. This can be found via your board manufacturer’s website, and not all of them support Resizable BAR yet. As of now, ASUS, ASRock, Colorful, EVGA, Gigabyte, and MSI all offer support. Even a few motherboard manufacturers go the extra mile to support older models of motherboards like the Z390. You will only have to know which options you work with.

As a final note, you will need to manually run the Resizable BAR in your BIOS. The associated documentation that you get from your motherboard manufacturer will guide you through this.

Once you’ve bypassed the hardware barriers, you just need to deal with your GPU itself. RTX 3060 GPUs and laptops already have the required VBIOS update, but other RTX 30 Series owners will need to update manually. In late March, Nvidia will release the necessary VBIOS update to enable the Resizable BAR. Additional instructions will be provided upon arrival.

Finally, a new Game Ready Driver update will prepare you for the Resizable BAR. This will do the trick, But you may need a newer version if you plan to do all of this in the future. You know, when the RTX 30 Series cards can actually be found.

Nvidia Resizable Tape Control

Turn it on, raise fps

After everything is updated, you can check whether the sizing bar is turned on in Nvidia Control Panel. Just open the program, go to System Information, and find the section where the feature is listed. If you did everything correctly, then “Yes” will be selected.

You’re then good to go! Sounds complicated, but Nvidia takes care of the rest. Any supported games that take advantage of this feature will automatically use it. You can expect 3-10% improvements in your frameset, which is a nice extra bump to add on top of something like DLSS. It might also make ray tracing more meaningful if you’re feeling fancy.

As of now, Assassin’s Creed Valhalla, Battlefield V, Borderlands 3, Forza Horizon 4, Gears 5, Metro Exodus, Read Dead Redemption 2, Watch Dogs: Legion All support this feature. Obviously, there are some heavy hitters here where you’ll need extra performance. Admittedly, this isn’t a big list. However, the BAR resize is It will become a standard. A lot of future games will be designed to take advantage of the Resizable BAR, which makes it an important update to put on your to-do list.
