If a monitor is 60hz refresh rate, don't any frames over 60 just get tossed? True some video cards will process really high FPS, but as I understand it the card loops to the monitor's buffer and Vsync enabled tells your video card to synchronize it's actions with the monitor. I read at Tom's hardware that "Vsync" was created to support CRT monitors and with Vsync turned off you can experience "tearing" as the two devices fall out of sync and the card puts more frame in the buffer than the monitor can actually display.
So Vsync off will allow the video card to render frames as fast as it wants to regardless of the ability of your monitor to keep up.
Vsync on will coordinate the video card and monitor but FPS can drop off quite a lot. The video card is told to wait until the monitor is ready to receive new data.
Nvidia cards have an adaptive Vsync option which enables the synchronization only when FPS exceeds the monitor's refresh rate, otherwise it is off.
This sound right?
