Games don't really support video cards heh. My guess is that you haven't installed the relevant drivers or that those drivers suck ass for OpenGL. Does it work well with Q3?

I download latest radeon drivers in oficial site,wolfcamql and quake3 is work normal, but ql is not work normal

Try resetting your driver's configuration to its defaults if you changed anything (I actually had that problem once). Try resetting your QL config as well perhaps. Apart from that... no idea. Except maybe trying older drivers.

Thanks I try latter and reported

Good, bye
