Hi. Is there any word about Adaptive Vsync in future releases of CCC drivers from AMD ?

I haven't heard anything, but I would never use such a feature anyway.  The whole point of using vsync is to prevent tearing, and that thing disables vsync whenever the frame rate drops below the refresh rate.

So if you have an especially resource-intensive game that stays below 60fps most of the time, you will have tearing most of the time.

The vastly superior solution for that type of game is to have vsync with triple buffering, which eliminates tearing and allows the maximum possible frame rate.

The problem with that, of course, is that most games don't allow you to enable triple buffering in their options, which means you have to force it with a third-party program like D3DOverrider (I say "like", but that's actually the only program I know which does it).

What would really be awesome is if AMD could figure out how to allow forced triple buffering without pissing off Microsoft, which has decreed that the number of buffers in a Direct3D program must be specified at the application level.  It would be so much easier if we could just check a box as with OpenGL.

AMD will never have this feature, because nVidia has Adaptive Vsync. TomsHardware article Here and Here The first being nVidia Adaptive Vsync (on a GTX 690) and second being AMD RadeonPro Dynamic Vsync (on the HD 7990)

There's two approaches there.  One is: "They have it, and it's cool, so we need it also, but we'll call it something different".  The other is "They have it, and it's lame, so we'll showcase something else, then point and laugh."  In this case, as Thanny said, it's lame.  However, the tricky part is still trying to figure out which one they will pick, because whether it's cool, or whether it's lame doesn't always matter.  That's marketing of technical widgets like adaptive vsync, in a nutshell.
