3. Display lag - Wikipedia

   en.wikipedia.org/wiki/Display_lag

   This lag time has been measured as high as 68 ms, [1] or the equivalent of 3-4 frames on a 60 Hz display. Display lag is not to be confused with pixel response time, which is the amount of time it takes for a pixel to change from one brightness value to another. Currently the majority of manufacturers quote the pixel response time, but neglect ...

   en.wikipedia.org/wiki/Lag_(video_games)

   Generally a lag below 100 ms (10 hz or fps) is considered to be necessary for playability. The lowest ping physically possible for a connection between opposite points on Earth crossing half of the planet is 133 ms. Other causes of lag result commonly in a lag below a playable 20 ms (50 hz or fps), or in the loss, corruption or jitter of the game.

5. Input lag - Wikipedia

   en.wikipedia.org/wiki/Input_lag

   Input lag or input latency is the amount of time that passes between sending an electrical signal and the occurrence of a corresponding action.. In video games the term is often used to describe any latency between input and the game engine, monitor, or any other part of the signal chain reacting to that input, though all contributions of input lag are cumulative.

6. Clock drift - Wikipedia

   en.wikipedia.org/wiki/Clock_drift

   Computer programs often need high quality random numbers, especially for cryptography. [4] There are several similar ways clock drift can be used to build random number generators (RNGs). One way to build a hardware random number generator is to use two independent clock crystals , one that for instance ticks 100 times per second and one that ...

7. Focus stealing - Wikipedia

   en.wikipedia.org/wiki/Focus_stealing

   This may be a few keystrokes due to reaction time, or may be more if the user's attention is not on the computer screen, e.g. typing while looking at the keyboard or while reading copy to the side, or if processor lag causes a delay (sometimes of several seconds) between the focus stealing event and the newly focused window displaying on the ...
