cliping is when stuff pops in and out of view, wich i have never seen on a radeon other than when its the fault of the game or api. i assume you are talking about tearing were you see horisontal ripples run through your screen and textures distoring for a split second when the video card looses its vertical syncronsation with the monitor. thats realy cool if they did fix it, now if only nvidia can do the same.
