In computer science and software engineering, busy-waiting, busy-looping or spinning is a technique in which a process repeatedly checks to see if a condition is true, such as whether keyboard input or a lock is available. Spinning can also be used to generate an arbitrary time delay, a technique that was necessary on systems that lacked a ...
If the game's controller produces additional feedback (rumble, the Wii Remote's speaker, etc.), then the display lag will cause this feedback to not accurately match up with the visuals on-screen, possibly causing extra disorientation (e.g. feeling the controller rumble a split second before a crash into a wall). TV viewers can be affected as well.
A typical example is when computer's graphical user interface (such as Microsoft Windows [a]) no longer responds to the user typing on the keyboard or moving the mouse. The term covers a wide range of behaviors in both clients and servers, and is not limited to graphical user interface issues.

It is caused by ...

Windows Vista introduced a hybrid sleep feature, which saves the contents of memory to hard disk but instead of powering down, enters sleep mode. If the power is lost, the computer can resume as if hibernated. Windows 7 introduced compression to the hibernation file and set the default size to 75% of the total physical memory. [18]
The typing loads between hands differs for each of the keyboard layouts. On QWERTY keyboards, 56% of the typing strokes are done by the left hand. As the right hand is dominant for the majority of people, the Dvorak keyboard puts the more often used keys on the right hand side, thereby having 56% of the typing strokes done by the right hand.
