NV 185.20驱动加入“环境光遮挡”特效

新年伊始，NVIDIA的185.20版驱动即在网络上泄露，除了性能上的全面提升外，该驱动还加入了一项新的3D特效：“Ambient Occlusion”环境光遮挡。

安装185.20版驱动后，在NV控制面板内即可找到该特效的开关选项，共有高中低三档可供选择。开启该特效后，游戏中3D场景内的物体表面当被其他物体遮挡时，其表面的环境光照强度会相应减小，最终显示的整个场景会更加真实。

以下就是《Crysis》开启关闭AO特效的画面对比：

AO关闭

AO开启

但需要注意的是，该特效会明显增加显卡负担。以下是《Crysis Warhead》的测试帧速：

测试系统 Core i7 965 Extreme @ 3.74GHz GeForce GTX 280 @ 685/2240MHz 分辨率 2048x1152

AO关闭 19FPS

AO Low 17.8FPS

AO Medium 16.6FPS

AO High 13.1FPS
