I just installed the Catalyst driver 10.5. The driver walked free (downloaded from Internet) not too bad and 3D is working. Then I installed ATI drivers, because the free driver does not support power control, the fan is running too, 3D train and wanted to see if with proper sound driver could pass through the HDMI (since it is the graphics card that must be part of the redirect apparently). The problem is always the same "tearing". There is no vertical sync x or xvideo but only on OpenGL. I am looking that someone will give the feedback for the Catalyst driver 10.5.
