Why Your Game Starts Lagging If your game starts lagging the moment you add lots of objects, it’s probably not the graphics. Naive collision detection checks every object against every other one and the work explodes fast. That’s why performance collapses. Quadtrees fix this by dividing space, so objects only check collisions with nearby objects instead of everything on screen. This is how games stay fast. #computerscience #algorithms #programming #GameDev #techtok
