Nvidia has released a GeForce 465.89 graphics card driver certified by Microsoft WHQL to all users. This version of the graphics card driver mainly brings support for the BAR function.
BAR originally refers to the base address register, which is the memory aspect, but here it mainly refers to the memory optimization function that Nvidia has previously disclosed in advance.
This function allows the CPU to call the GPU memory when it is supported. This is mainly achieved by eliminating the upper limit of 256 MB data transmission to achieve performance optimization purposes.
This allows the CPU to make fuller use of the graphics card memory to greatly improve the fluency of the entire process, thereby increasing the operating performance of games or creative applications.
According to Nvidia’s instructions, this version of the graphics card driver enables all RTX 30 series desktop graphics cards to support the BAR function. As for when the notebook version of the graphics card will support it, it is temporarily unknown.
It should be emphasized that if you want to support this function, you need not only the support of the graphics card but also the support of the processor and the motherboard. This function can only be used if both are supported.
The specific hardware support list will be announced by Nvidia on its website in the future. At that time, if users need to assemble high-performance desktops, they can refer to the Nvidia configuration list.
As a comparison, Nvidia also announced the performance of some games after enabling this feature. The tested games include F1 2020 and Cyberpunk 2077.
As for whether the old version of the graphics card, such as the RTX 20 series, will support this feature, Nvidia has not stated, but according to the past practice of Nvidia, may not pay too much attention to the old version of the graphics card.
