NVIDIA发布446.14版显卡驱动：拯救麦克斯韦老笔记本

　　win10之家5月28日消息 NVIDIA发布了GeForce 446.14 WHQL正式版显卡驱动，重点针对当下火热的Riot Games首款FPS游戏《Valorant》进行了优化，包括性能增强、Bug修复等。同时，新驱动还优化了《我的世界：地下城》、《崩解》(Disintegration)、《Crucible》三款游戏的性能，并支持在《Onward》中开启可变超采样抗锯齿(VRSS)。

　　Bug修复方面一共有九条，其中一条非常值得注意，那就是修复了采用麦克斯韦架构GTX 800M、900M系列显卡的笔记本在玩游戏时出现GPU占用率过高，导致温度过高、续航锐减的问题，这可都是四五年前的老本子了。

　　另外，新驱动还修复了开启SLI时在多款游戏中帧渲染时间大幅增加的问题，以及七彩虹GTX 1650显卡上安装失败的问题。
