Virtual reality sickness may have undesirable consequences beyond the sickness itself. For example, Crowley (1987) argued that flight simulator sickness could discourage pilots from using flight simulators, reduce the efficiency of training through distraction and the encouragement of adaptive behaviors that are unfavorable for performance, compromise ground safety or flight safety when sick ...
Too much video game playing may cause vision problems. [11] Extensive viewing of the screen can cause eye strain, as the cornea, pupil, and iris are not intended for mass viewing sessions of electronic devices. Using video games for too long may also cause headaches, dizziness, and chances of vomiting from focusing on a screen.
As all clients experience some delay, implementing these methods to minimize the effect on players is important for smooth gameplay. Lag causes numerous problems for issues such as accurate rendering of the game state and hit detection. [7] In many games, lag is often frowned upon because it disrupts normal gameplay.
Stuttering could have a significant negative cognitive and affective impact on the person who stutters. Joseph Sheehan described this in terms of an analogy to an iceberg, with the immediately visible and audible symptoms of stuttering above the waterline and a broader set of symptoms such as negative emotions hidden below the surface.

Micro stuttering is a quality defect that manifests as irregular delays between frames rendered by a graphics processing unit (GPU). It causes the instantaneous frame rate of the longest delay to be significantly lower than the frame rate reported by benchmarking applications such as 3DMark , which usually calculate the average frame rate over ...
A typical video tearing artifact (simulated image) Screen tearing [1] is a visual artifact in video display where a display device shows information from multiple frames in a single screen draw.
The dopamine hypothesis of stuttering attributes to the phenomenon of stuttering a hyperactive and disturbed dopaminergic signal transduction in the brain. The theory is derived from observations in medical neuroimaging and from the empirical response of some antipsychotics and their antagonistic effects on the dopamine receptor.
Cluttering is sometimes confused with stuttering. Both communication disorders break the normal flow of speech, but they are distinct. A stutterer has a coherent pattern of thoughts, but may have a difficult time vocally expressing those thoughts; in contrast, a clutterer has no problem putting thoughts into words, but those thoughts become disorganized during speaking.
