How to give full play to the performance potential of gaming notebooks has always been a big problem. In addition to upgrading at the hardware level, today's design ideas have begun to focus on the combination of software and hardware. For example, the Dynamic Boost 2.0 technology launched by hardware giant NVIDIA and the earlier Optimus technology focus on giving full play to the hardware potential of graphics cards from the software and driver levels.
However, NVIDIA's optimizations for players do not stop there. With the Resizable BAR technology launched by GeForce RTX GPUs, it can easily improve the performance of up to 10% after opening, which is not quite a black technology! So where is this Liberatable Bar?
Break video memory access restrictions
To understand the principle behind the Resizable Bar, you must first understand the video memory of the graphics card (or known as the frame buffer), which is used to store the data that the graphics card chip has to process or process. Flagship graphics cards like the GeForce RTX 3080 Laptop GPU will come with high-capacity video memory, but traditional BIOS limits the size of communication data to 256MB. As a result, when the CPU wants to share some data with the GPU, there will be a queue of read commands, resulting in a certain performance loss.
In the face of games with lower configuration requirements, the 256MB limit has little impact and is acceptable. However, in the face of today's 3A masterpieces with hundreds of G, the queue congestion caused by the command queue of video memory transfer data will cause more serious performance loss.
NVIDIA's Resizable BAR technology is designed to break this limitation, which can dynamically adjust the limits of extracting data, prevent video memory read requests from forming a queue waiting situation, improve the efficiency of video memory reads, and achieve the purpose of improving performance.
At present, Resizable BAR technology has also supported a number of mainstream games, including "Assassin's Creed", "Forza Horizon 4", "Red Dead Redemption 2", "Cyberpunk 2077" and more than ten major games. As a new technology, there will be more games in the future to add technical support, I don't know if there are any games you want to play?
According to NVIDIA's official data, after opening The Liberatible BAR, the average frame rate of the Assassin's Creed: Temple of Heroes game increased by 9.5%, cyberpunk 2077 increased by 5.9%, and in "F1 2020" increased by 11.9%, the game frame rate increase was more obvious.
The test results also met expectations, because the Resizable BAR is a technology developed for memory reading, and its improvement is especially significant in game settings that consume a lot of video memory resources, such as texture (such as "texture quality"), shaders (such as "shader quality"), geometry options (such as "surface subdivision") set to higher, the contrast gap after opening is more obvious, and when turned on on flagship GPUs with large video memory, such as GeForce RTX 3080 Mobile, The lifting effect is even more pronounced.
How to open the Resizable Bar
I think many friends can't wait to try it! So how exactly does Resizable BAR turn on? For GeForce RTX gamebooks alone, simply upgrade to game Ready driver 465.89 WHQL (released March 30, 2021) and later, and most GeForce RTX 30 series games will have Resibility BAR (resizable base address register) turned on by default.
In the NVIDIA Control Panel or GPU-Z program, you can view the activation of the Liberatable BAR option. If it is not enabled, you can also enter the BIOS to view the relevant settings and turn it on yourself.
The Razer Blade 15 Elite Edition, equipped with GeForce RTX 3080, requires the Resibility BAR to fully exploit performance. Razer Spirit Blade 15 Elite edition body thickness is only 16.99mm, in such a compact body, with the vacuum chamber vapor plate cooling system and NVIDIA Dynamic Boost 2.0 technology to achieve the highest 105W graphics card performance release. Coupled with the technical optimization of Resibility BAR, there is one less performance bottleneck, so that thin and light games can easily challenge the AAA masterpiece!
Comparable to the top gaming notebook in terms of hardware specifications and surpassing many opponents in terms of portable features, Razer Spirit Blade 15 Elite Edition is definitely a dream game machine in the hearts of many people. With the blessing of NVIDIA Resizable BAR, this performance beast must have a more powerful frame rate performance. Want to open the black with your friends and experience the fun of light chasing + high brushing? Razer Spirit Blade 15 Elite Edition must be your dish!
