我已经安装了驱动，为什么在显示选项里不能打开“启用硬件加速”
rt我用的是ATI 镭9600 Mobility芯片。但是安了驱动在显示选项中的“启用硬件加速”一项是灰的。
我用glxgears和fglx_gears测试，结果都是85FPS.
fglxinfo结果是：

ATI卡可能也需要安装专用3D驱动 我已经安好了驱动，那是不是说我的系统就已经可以使用ati提供的3D加速功能了？
不过我的glxgears和fglxgears只有85FPS，是为什么？
谢谢你的回复。 如果你安装好了ATI的专用驱动，按道理glxgears不应该只有85FPS…… 我也很纳闷，这个数值比我的mx400还有低。
不过倒是和屏幕刷新率一样，和这个有关系么? 估计和刷新率没关系 我想也是，只是可惜了我的9600M 终于搞明白了。原来我在惊醒高级设置时不小心打开了“垂直同步”选项，结果导致3D输出的帧数保持与显示器刷新率一致。
现在把它关掉就好了。我的fgl_xgears测试可以达到650FPS。
希望以后有哪位兄弟安装ati的驱动，可千万要小心看看那些高级选项。
