No, it makes no sense to use buffering at all if VSync disabled. It is to enable VSync (and thus have no tearing) but prevent FPS limitations (as OrbWeaver wrote). Absolutely. I mentioned FXAA just to say that it could be enforced from driver settings but triple buffering not working even when enforced. With NVidia it is double buffering by default. And there is only one option in driver settings, actually I don't know if it is for DirectX only or for OpenGL too. But is there any chance to tweak it from game configs or console?
