再也不用重启进BIOS了！NVIDIA App将内置Resizable BAR开关：一键解锁CPU满血访问显存_我的网站

A |     8月26日消息，NVIDIA GeForce技术推广专家Jacob Freeman今日在X平台爆料，NVIDIA计划在未来的NVIDIA App升级中为Resizable BAR新增控制选项。

B |     According to media reports, the newspaper Beijing Daily published a story on Monday afternoon quoting Cai Qi, the Communist Party of China’s secretary in Beijing and a former mayor of the city.,“In the next five years, Beijing will unremittingly grasp the normalization of epidemic prevention and control,” the story originally quoted Cai as saying, according to the UK Guardian.,Now, the article only says the city will “make unremitting efforts to normalize epidemic prevention and control” to “control quickly and resolutely block the transmission channels of the epidemic.”,It goes on to note the various efforts that must be improved, including a “normalized nucleic acid testing and key screening” process, regularizing cleaning and inspection of public spaces, and controlling entry and exit of the vast city of 21.5 million, which is deeply connected with the surrounding Hebei Province and nearby coastal metropolis of Tianjin.,China’s Economy Got $26 Billion Boost From Gov Buying 11 Billion Covid-19 Tests - Report13 June, 22:01 GMT,China adopted the “Zero Covid” policy in 2021, when the arrival of the Delta variant of SARS-CoV-2, the virus that causes COVID-19, brought an increasingly stubborn new outbreak. However, the principles underlying it - that mass lockdowns, with logistical networks funneling food, supplies and medicine to residents under quarantine while medical workers test the entire population for infection - were forged in early 2020, when China fought off the world’s first outbreak of the virus.,Throughout 2021, the policy was extremely successful, limiting mainland China to just two COVID-19 deaths that year. By comparison, at least 415,000 Americans died of the virus in 2021.,However, it wasn’t until early 2022 that the Omicron variant, even more infectious than Delta and with a penchant for causing asymptomatic cases, really put China’s “Zero Covid” policy to the test. Between the beginning of April and the beginning of June, the Chinese government spent some $26 billion on COVID-19 tests as huge cities like Shanghai, Shenzhen, and Xi’an were placed in lockdown for weeks at a time and their tens of millions of residents tested several times in an attempt to track down, isolate and treat all cases of the disease.,40% of Kids Aged 0-3 Suffer From Long COVID, Which Lasts at Least Two Months - Lancet Report23 June, 12:37 GMT,Despite its success at preventing mass death among its 1.4 billion people, the Chinese government has been extensively criticized by the West, which has variously accused them of lying about the extent of the outbreak, terrorizing its population with the lockdowns, and claiming that the policy in unsustainable. When World Health Organization (WHO) Director General Tedros Adhanom Ghebreyesus suggested in May that China would be better off if it abandoned “Zero Covid,” Beijing fired back.,“The purpose [of Zero Covid] is solely to protect people’s life and health to the greatest extent possible and underpin sustained, sound and steady economic and social development,” Chinese Foreign Ministry spokesperson Zhao Lijian said at the time. “In China, we have the foundation, the conditions and the capability to achieve dynamic zero-COVID. We have every confidence in winning this hard battle and making greater contributions to the united global response.”,A study published in May by researchers at Shanghai’s Fudan University and at Indiana University in the United States warned that if China’s “Zero Covid” policy were removed and the respiratory virus allowed to spread unimpeded across Chinese society - as has happened in most other countries - it would “generate a tsunami of Covid-19 cases” that would kill at least 1.5 million people.,Just over 5,200 people in China have died of COVID-19 since it appeared in late 2019, while about 6.3 million have died globally, including 1 million in the United States.。    

    这项功能将提供自动、启用和禁用三种模式，默认选择自动模式。届时玩家无需进入BIOS，即可在NVIDIA App中直接控制该功能。     Resizable BAR全称可调整大小的基址寄存器，是一项PCIe接口技术。传统架构下，CPU与显存通信存在瓶颈，每次只能以256MB为单位的小区块访问显存。    启用Resizable BAR后，256MB的限制被彻底打破，CPU可以直接、并发且完整地读取整个显存容量。这一功能与AMD的Smart Access Memory本质上是同一技术。

C |     在性能提升上，Resizable BAR在不同游戏中带来的增益各不相同。在《赛博朋克2077》等对显存带宽敏感的大型3A游戏中，开启后可获得约5%至12%的帧率提升。部分游戏如《刺客信条：幻景》平均可提升至少10FPS。

D |          NVIDIA App将提供三种模式。自动模式为默认选项，系统会根据具体游戏和硬件配置自动判断是否启用。启用模式强制开启Resizable BAR，禁用模式则强制关闭。玩家还可以为不同游戏单独配置设置。该功能预计随下一版GeForce Game Ready驱动一同推送。    目前NVIDIA尚未公布具体上线日期。包含该功能的正式版本预计将于9月发布。届时玩家无需修改BIOS设置，即可在NVIDIA App中灵活控制Resizable BAR的开关状态。
