I recently acquired an 8600GT, replacing my X800GTO. I normally like to play my MMO in one window and watch TV in another. With the x800GTO, this was no problem. With the 8600GT, though, whenever the game window is active, the TV becomes very choppy (although sound is fine). Is this a property of nVidia cards? I have tried disabling DirectX10 and lowering the graphical quality of the game, but the TV signal always become choppy.
