这个glxgears的输出正常吗？

fender010

硬件如下：

cpu是amd的5200+，

显卡是nvidia的9500gt有256M的ddr3显存，

显示器是菲利普的190vw9，

主要参考资料：http://www.gentoo.org/doc/en/dri-howto.xml

按照文档，在这一步，我没有找到自己的显卡，

1. Processor type and features --->
2. <*> MTRR (Memory Type Range Register) support
3. Device drivers --->
4.    Graphics support --->
5.    <M> /dev/agpgart (AGP Support) --->
6.       (The agpgart option is not present on 64-bit kernels; just choose your chipset support.)
7.       <M> Intel 440LX/BX/GX, I8xx and E7x05 support
8.       (Enable your chipset instead of the above.)
9.    <M> Direct Rendering Manager (XFree86 4.1.0 and higher DRI support) --->
10.       <M> (Select your graphics card from the list)

但是我运行glxinfo | grep rendering命令时输出如下：

direct rendering: Yes

但是我感觉cpu占用有点高啊，详细看图。

我在另外的一台集成intel显卡的debian上运行glxinfo，结果如下：

1. glxinfo | grep rendering
2. direct rendering: No (If you want to find out why, try setting LIBGL_DEBUG=verbose)

复制代码

但是运行glxgears时fps居然和gentoo的那个机器数值差不多， :yun:

具体内容看图。

2603301009

你 该装官方驱动的！！
9500gt该好几k的，我的1600都3k多！

fender010

I forgot this: http://www.gentoo.org/doc/en/nvidia-guide.xml

:yun:

Next time, when I encounter some "strange" problem I will check our documentation firstly.

Now the pfs value is reasonable, but the cpu useage is still high than I expected.

肯定不正常，估计应该要有4000~6000，compiz开启后。
