And without vaync at least you can see a difference between 60 and 80 for example
See everyone, here comes one now.
Let me explain something to you. A 60Hz monitor only refreshes the screen 60 times a second. It is a physical impossibility for that monitor to display 120 frames per second. That means half the frames are discarded from the buffer. What do you think causes screen tearing and why it goes a way when you enable v-sync? It's caused by miscues between the buffer and the monitor refresh rate resulting in a portion of the screen being drawn with a different frame from the rest. V-sync forces the GPU to output at the same rate as the monitor.
The hertz (symbol Hz) is the unit of frequency in the International System of Units (SI). It is defined as one cycle per second. One of its most common uses is the description of the sine wave, particularly those used in radio and audio applications, such as the frequency of musical tones. The unit is named for Heinrich Rudolf Hertz, who was the first to conclusively prove the existence of electromagnetic waves.
The hertz is equivalent to cycles per second. In defining the second, the International Committee for Weights and Measures declared that "the standard to be employed is the transition between the hyperfine levels F = 4, M = 0 and F = 3, M = 0 of the ground state 2S1/2 of the cesium 133 atom, unperturbed by external fields, and that the frequency of this transition is assigned the value 9 192 631 770 hertz" thereby effectively defining the hertz and the second simultaneously.
In English, "hertz" is also used as the plural form. As an SI unit, Hz can be prefixed; commonly used multiples are kHz (kilohertz, 103 Hz), MHz (megahertz, 106 Hz), GHz (gigahertz, 109 Hz) and THz (terahertz, 1012 Hz). One hertz simply means "one cycle per second" (typically that which is being counted is a complete cycle); 100 Hz means "one hundred cycles per second", and so on. The unit may be applied to any periodic event—for example, a clock might be said to tick at 1 Hz, or a human heart might be said to beat at 1.2 Hz. The rate at which aperiodic or stochastic events (such as radioactive decay) occur is expressed in becquerels, not hertz. Whereas 1 Hz is 1 cycle per second, 1 Bq is 1 aperiodic event per second.
Note the part that reads "1Hz is 1 cycle per second"Edited by GoDucks2014 - 10/3/14 at 5:55pm
