外媒Techspot刚刚放出了一份《古墓丽影9》的各显卡和CPU跑分图。PC版的《古墓丽影9》支持DX11，支持景深、高环境光遮蔽，曲面细分，超级AA等等。还特有AMD的TressFX实时头发物理系统，比主机版强了不少。
也正是因为飘柔效果，N卡在此游戏吃瘪，目前来看A卡更具优势。但是就在刚刚A和N都放出了新的驱动，据说N卡此驱动中已经解决这个兼容问题，而A卡也有小幅提升。
测试方法：
使用了27款支持DX11的显卡，不同价位的A和N卡都有，搭配i7-3960来确保没有CPU方面的瓶颈。使用Fraps记录游戏第一关的90秒游戏过程，从劳拉逃出洞穴开始。分辨率使用1680x1050, 1920x1200 和2560x1600，开启DX11。使用极限，超高和高三种画质预设。
