What Actually Is Happening When a Videogame Loads? (And is loading an offline vs. online game different?)

245 views

Hi All!

Was very curious what actually occurs when loading a game up to play! I also was curious if the process is the same for a singleplayer game versus a multiplayer game?

Thanks!

There are two places things are stored for a game: Storage (Disk, Hard Drive, SSD, etc.) and memory (RAM). Storage (even SSDs) are slow compared to memory, so things need to be loaded from storage to memory to actually be used by the game. The GPU (graphics card) also has it’s own memory (VRAM) that 3D models and images need to be loaded into before they can be used so that takes some time as well.

There also might also be certain programming instructions like “take this one 3D model of a statue from storage and place 10 copies of it in memory,” or “generate this terrain based on random numbers,” that take processing time too.
