ATI显卡驱动的问题(MOBILITY XPRESS 200)
本人安装的是红旗5。0,显卡是ATI MOBILITY RADEON XPRESS 200
在安装好显卡驱动后经查看如下:
-----------------------------------------
]# fglrxinfo
display: :0.0 screen: 0
OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: RADEON XPRESS 200M Series SW TCL Generic
OpenGL version string: 1.3.5461 (X4.3.0-8.19.10)
-----------------------------------------
# glxinfo | grep rendering
direct rendering: Yes
-----------------------------------------
可是测试的时候FPS却只有100~200左右:
-----------------------------------------
# glxgears
1325 frames in 5.0 seconds = 265.000 FPS
1217 frames in 5.0 seconds = 243.400 FPS
1302 frames in 5.0 seconds = 260.400 FPS
1229 frames in 5.0 seconds = 245.800 FPS
-----------------------------------------
# fgl_glxgears
Using GLX_SGIX_pbuffer
229 frames in 5.0 seconds = 45.800 FPS
255 frames in 5.0 seconds = 51.000 FPS
236 frames in 5.0 seconds = 47.200 FPS
-----------------------------------------
看网上说的fglrxinfo检测出显卡就说明驱动以打上了,direct:YES说明3D加速开启,可是测试祯数确好像很慢,随便拿个影片来测试都一卡 一卡的,我想问一下这就是这显卡的正常水平了?还是说我没配置好没发挥出显卡的性能,虽说集成显卡对3D不怎么好,可是也不至于看影片会一卡一卡的就好像没打驱动或使用了 软3D加速一样```
PS:本人还是初学者````如解决方法涉及比较深的地方还请达人们能详细说明`万分感谢`````
