In StarCraft 2, some cutscenes are "animated" and don't use Direct3D, so when using RadeonPro's "Direct3D Tweak" vsync option (with triple buffering), these types of cutscenes aren't getting vsynced.
If I enable vsync via the "Visual" tab "Always on, unless app specifies", then these types of cutscenes do get vsynced. But then I'm concerned about having two vsyncs on at once. If I disable the "Direct3D Tweak" vsync, I'm concerned that I'll be losing triple buffering.
Does anyone know the effects of having two vsyncs on at the same time? Does one use triple-buffering while the other doesn't?
