NVIDIA released itsGeForce Game Ready 465.89 WHQL drivertoday. It features multiple gaming-friendly feature updates including NVIDIA Reflex support for Rainbow Six Siege to help combat in-game latency as well as NVIDIA GPU optimization tweaks for the upcoming Square Enix title Outriders. Arguably the most noteworthy inclusion of the 465.89 driver update is its resizable BAR support for all NVIDIA RTX 30 series desktop GPUs, otherwise known as some of thebest graphics cardoptions available.

What resizable Base Address Register (BAR) does is allow CPUs and GPUs to moreefficiently transfer game assets. It does this by removing the 256MB data transfer cap, enabling a CPU to take advantage of all of a GPU’s VRAM simultaneously rather than just bite-size chunks of it. This can result in boosted hardware performance during gameplay.

According to NVIDIA, these performance boosts can be as large as 12 percent in supported games. NVIDIA clarifies that resizable BAR support requires more than just an RTX 30 series GPU, such as anNVIDIA GeForce RTX 3060. You’ll need a compatible CPU and motherboard as well, which NVIDIA lists in detail on its website.

At the moment, NVIDIA hasn’t commented on whether full or partial resizable BAR support will come to RTX 20 series GPUs.
