A pause separates intent from a passing cursor
In a game, the cursor can sweep across several inventory slots, buttons, or map markers in a fraction of a second. If each crossing opened a tooltip immediately, labels would pile up visually and compete with the action. A short wait acts as a simple test of intent: the player has to hold the cursor over one target rather than merely pass through it.
The timer is part of the interface
When the pointer enters a target, the game starts a timer. Moving away before it runs out cancels the pending tooltip; staying put long enough lets the text appear. That small rule makes quick navigation feel quiet while still allowing a player to stop and inspect an unfamiliar item or control.
The delay is a tradeoff. Too little, and tooltips flicker into view during routine movement. Too much, and players may not realize that useful information is available, or may have to wait repeatedly while comparing items. Designers therefore have to consider what the tooltip is for: a brief label can appear sooner than a detailed explanation that would interrupt play.
The result is a subtle distinction between moving through a game interface and asking it a question. A cursor that keeps moving gets out of the way; one that settles signals, “Tell me more.”
