Consistent refresh rates, typically 60 frames per second, ensure that animations and interactions feel natural and responsive. Variations can cause jitter or lag, diminishing immersion. Studies have shown that smooth visual updates increase player satisfaction and reduce fatigue, especially in fast-paced genres like shooters or racing games.

b. Examples from classic and modern games demonstrating visual updates

  • Pac-Man: Basic sprite animation with frame cycling to animate ghosts and Pac-Man himself.
  • Modern titles: Games like «Fortnite» use rapid visual updates to render dynamic environments, character movements, and effects, all synchronized with the rendering cycle.

c. The psychology behind visual freshness and player immersion

Frequent visual updates contribute to a sense of vitality and realism, which psychologically enhances immersion. When players observe consistent and smooth animations, their brain perceives the game world as alive, fostering emotional engagement and sustained interest. This is why high refresh rates and dynamic visual renewal are critical, especially in narrative-rich or competitive games.

4. Case Study: «Chicken Road 2» as a Modern Illustration of Visual Renewal Cycles
