For me ATT is an alternative for CCC. I have the best performance by using only the Driver + ATT. I know how to make it work with CCC, but if I would use that ATT would be useless for my need. I have a problem with video files, and old problem that many users seem to have from time to time, generaly speaking (ATI, Nvidia users -happens with a new driver release or so...). All the video files that use OVERLAY function are "BLACK" - sound play but no video, unless I chose a different rendering mode. The thing is they look better with overlay and even If I would chose a different rendering mode, I couldn't use video streaming which is Overlay only. For some reasons I can change Overlay settings from ATT: Unchecking "Application Decide" and using personal setting doesn't seem to work. Cause as soon as I'm out of that panel, it resets back. Any suggestion beside using Crappy Control Central ? PS. Only de VIDEO shows a black image, the rest is fine.
