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.
Cache hierarchy, or multi-level cache, is a memory architecture that uses a hierarchy of memory stores based on varying access speeds to cache data.Highly requested data is cached in high-speed access memory stores, allowing swifter access by central processing unit (CPU) cores.
The virtual machine uses substantial memory. In Java, a composite object (class A which uses instances of B and C) is created using references to allocated instances of B and C. In C++ the memory and performance cost of these types of references can be avoided when the instance of B and/or C exists within A.
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.
This way, only the offending program crashes, and other programs are not affected by the misbehavior (whether accidental or intentional). Use of protected memory greatly enhances both the reliability and security of a computer system. Without protected memory, it is possible that a bug in one program will alter the memory used by another program.
Input/output operations per second (IOPS, pronounced eye-ops) is an input/output performance measurement used to characterize computer storage devices like hard disk drives (HDD), solid state drives (SSD), and storage area networks (SAN).
Often the effect is stronger on the target than on anything else hit. See also: Splash damage. Area of effect can also refer to spells and abilities that are non-damaging. For example, a powerful healing spell may affect anyone within a certain range of the caster (often only if they are a member of the caster's party). Some games also have ...
The introduction of color television technology made it necessary to lower that 60 FPS frequency by 0.1% to avoid "dot crawl", a display artifact appearing on legacy black-and-white displays, showing up on highly-color-saturated surfaces. It was found that by lowering the frame rate by 0.1%, the undesirable effect was minimized.
