请教ati9550开源驱动3d性能不佳

jnds

pacman -S xf86-video-ati libgl

xorg.conf应该也没写错，照arch的wiki写的

glxinfo | grep direct rending 也是yes

但是

glxgear 只有140帧

而且kde的桌面特效无法开启

我卸载驱动，又重装了一次就好了
arch也抽风么
晕

jnds

搞清楚了
运行
LIBGL_DEBUG=verbose glxinfo > /dev/null
可以看到
libGL: OpenDriver: trying /usr/lib/xorg/modules/dri/r300_dri.so
原来r300_dri.so这个文件不见了，重装了一次就看到这个文件了

zhuqin_83

use exa rather than xxa, should be much faster.
also add

1. Option      "AccelDFS"                "on"

我的显卡也是ATI R9550，试试再说。
