再问为什么NVIDIA驱动在FC4、FC5中3D加速为何这么慢？

shuifu

硬件：
AMD XP1800
GeForce4 MX 440 AGP 8x

ML、SUSE发行版本安装NVIDIA驱动明显比FC系列版本中快，这是为什么？
内核升级，重新编译都不能达到其他发行版的加速效果，这是为什么？
fps最高只能到1330左右，其他linux版本下可以达到3200左右。
有什么办法吗？
在Xgl Compiz 滚动桌面或者拖拽窗口时有明显的锯齿。
看下图：

驱动没装好？改成16bit颜色看看？

我的GF5700也不过才3300左右，suse/mdv/ubuntu/fc里都是这个数

light_zls

怀疑楼主是不是改了nvidia-settings里面的设置。我这边改到最低的时候是3300左右（我的卡是FX5200），开2x的反失真的时候就只有1400了，开到8x的时候就只剩下100多。建议楼主看一下nvidia-settings

shuifu

谢谢楼上2位兄弟。
nvidia-settings用不了了？没有选项了，真******************的奇怪。

light_zls

用不了的话，很可能没有安上驱动。你把glxinfo的结果贴上来瞧瞧。

shuifu

驱动很肯定已经在工作了，fps和没有装驱动的时候差不少。没有安装驱动时候只有300左右，现在能到1300左右

NVIDIA X Server Settings里面的选项没有了,如图：

好像是设置有问题，你的direct rendering是关着的。。。。。。

direct rendering: No
server glx vendor string: SGI
server glx version string: 1.2

已经充分说明了驱动没有装好

Mandriva

错误的回答，使用Xgl就是direct rendering: NO；
按照楼主的配置，glxgears值基本正常；
如果还想快些，可以试着在xorg.conf中设置
Option "NVAGP" "1"，不过需要重新编译内核。
建议看看/proc/drivers/nvidia/agp/目录下的card, host-bridge, status的内容
就清楚了。
