Open world video games require a lot of processing power because they have to manage vast virtual environments in real-time, including many interactive elements, non-player characters, and complex visual effects.
Open-world video games are often very demanding because they need to display an enormous amount of detail in real time. Each texture (the visual surface of an object or character) must be loaded into memory to be displayed accurately. The more numerous and detailed these textures are, the harder the graphics card and processor have to work. The rendering distance also plays a significant role: the farther you can see, the more the system has to calculate what is displayed in the distance. Additionally, there are visual effects such as shadows and lighting, reflections on water, foliage that moves with the wind, and realistic weather that changes. All of this requires a substantial amount of calculations performed continuously, explaining why these beautiful open worlds consume so many computing resources.
Open-world games must constantly manage and update a ton of dynamic elements. When a player progresses or interacts with the environment, there are hundreds of simultaneous events to monitor continuously. If the weather changes suddenly, developers calculate in real-time how the rain affects visibility, NPC behavior, or even the puddles forming on the ground. When you enter a village, every character you encounter follows their daily routine, moves, speaks, and reacts autonomously. All this places a demand on processors for ongoing real-time calculations, requiring a lot of resources to keep a living and responsive universe.
Open-world video games constantly deal with numerous physical interactions, such as gravity, object collisions, and the precise propagation of fire, water, and weather elements. Each object can react individually and in real-time to surrounding events: an arrow shot can pierce a barrel that explodes, sending debris in all directions. This level of realism involves frequent and complex calculations, often resource-intensive, as the game must simultaneously account for every object, every projectile, and every movement to create a believable simulation. The larger and more detailed the world, the more numerous and complicated these calculations become for the processor to manage.
Open-world video games feature NPCs (non-player characters) capable of dynamically reacting to the player's actions. This requires the computer to constantly calculate decisions in real time: where the characters are going, how they react to an event, what route they take to navigate around an obstacle, or what attitude they adopt in response to the player's actions. This artificial intelligence must be convincing and varied so that each interaction feels real. As a result, significant computing power is needed to simultaneously manage the realistic behaviors, decisions, and dialogues of dozens, if not hundreds, of involved characters in real time. Everything must be fluid, credible, and coherent, which places a heavy burden on the computing capacity of machines.
An open-world video game contains an astronomical amount of information such as environments, characters, sounds, and events. It's impossible to load everything into memory at once; it would be far too heavy. Therefore, the game continuously loads data as you explore, in real-time and discreetly in the background: this is streaming. This means that the hard drive or SSD is working almost all the time. The game must anticipate your movements to load the next part before you even arrive, in order to avoid crashes or annoying slowdowns. All of this requires a good bandwidth from the storage, a significant amount of RAM, and a highly optimized management of these resources to ensure that your exploration remains smooth and immersive.
Did you know that some studios use complex weather systems that influence not only the visual environment but also the physical reactions of characters, vehicles, or objects? This requires additional computing power, adding to the technical complexity of open-world games.
Did you know that to create a believable world, some video games use 'procedural algorithms' capable of automatically generating entire landscapes, vegetation, and various objects? This requires significant real-time computing power to continuously produce new areas.
The famous game GTA V features a map covering over 127 square kilometers to explore without any loading screens. This immersive fluidity requires significant hardware resources for the continuous management of the game's data.
To provide credible artificial intelligence, certain open-world video games must simulate thousands of non-player characters (NPCs) in real-time, each with their own daily routines, which represents a significant computational load.
The first thing to check is to refer to the recommended configuration for the game in question or to use online tools dedicated to comparing video games and graphics performance. You can also conduct a real-world test with a benchmarking application to precisely identify the limitations of your GPU.
Mainly, the graphics card (GPU) and the amount of system memory (RAM) influence graphical performance and the quick loading of environments. The processor (CPU) also plays a very important role in managing complex interactions, physical simulations, and the artificial intelligences present in open-world games.
Yes, in many cases, increasing the amount of RAM helps reduce slowdowns related to frequent data loading. This allows the game to keep more elements of the virtual world in memory, limiting stutters and improving smoothness during exploration.
You could start by reducing the display distance or the density of dynamic elements (characters, terrain details). These settings consume a significant amount of processing power, and lowering them provides a substantial performance boost while maintaining an enjoyable level of immersion.
Open-world games must load a massive amount of textual, graphical, and audio data from complex and detailed environments. The larger and more interactive the world, the more significant the initial loading times are likely to be, in order to avoid excessive loading during gameplay.
Open-world video games display a greater amount of graphical elements and require constant loading of significant data from the virtual world. They utilize considerable system resources to manage a vast interactive map, dynamic AI, and advanced physical simulations, which explains why you might experience slowdowns.
