The History of CGI in Games: From Early Experiments to the Gold Standard

Do you remember your first games? We started with “Tamagotchi” and “Tetris,” with its simple shapes and basic visuals, and then moved on to fully realized 3D games. Computer graphics in gaming have come a long way—from pixels to full photorealism. Today, these are no longer flat worlds, but carefully crafted digital universes with precise physics, geometry, and lighting. So, when did the journey of CGI in games actually begin?

CGI Video Games: The Atari Era

It’s no secret that before the advent of home computers, entertainment meant arcade machines. Game developers used vector graphics instead of pixels: points on a coordinate system were connected with lines to form shapes and objects. The games looked like animated blueprints or frames from the sci-fi films of that time. A striking example of vector graphics creating the illusion of 3D was Atari’s Battlezone (1980).

Players looked through a periscope, seeing a barren landscape and angular tanks drawn with glowing vector lines on the screen. By today’s standards, it may seem extremely minimalist and primitive. However, in the early 1980s, it was considered a breakthrough—a first step into 3D space that left players breathless.

The development of computer graphics in games was largely defined by sprites—small pixel blocks used to represent characters, objects, and interface elements. The level of detail and color palette was minimal, but this didn’t limit the creation of games like Donkey Kong (1980) and Pac-Man (1981). Characters consisted of just a few dozen pixels. In Pac-Man, technical limitations meant the main character was simply a yellow circle that ate objects, while in Donkey Kong—there was Jumpman (later Mario) and a giant gorilla.

Creating game graphics came with technical challenges: memory was measured in kilobytes, and every pixel counted. Artists had to get creative, reusing colors, simplifying shapes, and often relying on flickering sprite animations. It wasn’t until the late 1980s that 16-bit consoles appeared. The Sega Genesis and SNES expanded color palettes and improved image resolution. This marked what many consider the golden age of game development, giving us classics like Sonic, Super Mario World, and F-Zero.

3D Graphics in Games: The PlayStation and N64 Era

The mid-1990s marked a turning point in the evolution of pixel-based graphics. The shift from 2D to 3D models allowed for more vivid characters with volume, depth, and angles. Game developers began exploring polygons—small triangles used to build three-dimensional shapes. In addition, to make 3D graphics look realistic, programmers and CGI artists had to tackle more fundamental challenges:

1. Texturing. Early CGI games looked lifeless, so adding detail became a priority. Grass on lawns, brick walls, grains of sand—these became possible only because artists learned how to wrap flat images around three-dimensional objects.
2. Z-Buffering. This technology ensured that objects closer to the camera correctly obscured those farther away, giving the game scene a sense of depth.
3. Anti-Aliasing. Early 3D models were too angular and sharp. To make the visuals smoother and more pleasing to the eye, polygon edges were smoothed.

Which Games Became Icons in the Early 3D Era?

In 1996, Nintendo announced the release of Super Mario 64 for the N64 console. Many were skeptical about such changes, wondering how players would control a character in three-dimensional space and judge distances. Shigeru Miyamoto’s team designed the joystick to control walking speed and jump height. In addition, they “tamed” the camera: it followed Mario and could be zoomed in and out.

While Nintendo was teaching players to master the joystick, Core Design introduced a heroine made entirely of polygons. Lara Croft from Tomb Raider became a true star in CGI games. The world saw realistic character proportions, abandoned tombs, and ancient traps. Lara moved, ran, flipped, and fired dual pistols, making millions of players forget that her arms and legs were just a collection of textured triangles. She came to life in the imagination of players, proving that the graphics had done their job. As we know, the game later inspired films starring Angelina Jolie.

The phenomenon of 3D gaming in the mid-1990s was Final Fantasy VII for the PlayStation. The three-dimensional gameplay was combined with pre-rendered CGI videos. During cutscenes, the screen displayed highly detailed character faces, Cloud’s realistic hair, and Aeris’s tears. This striking contrast evoked strong emotions and captured players’ imaginations.

CGI for Games: The PS2, Xbox, and GameCube Era

The early 2000s expanded the technological and technical possibilities of video game development. With the release of the PS2, Xbox, and GameCube, the world saw more complex computer graphics gradually approaching realism. A key change was the evolution of polygons and an increase in their number. 3D characters were no longer angular and gained more detail, while their movements became noticeably more natural.

Major changes also occurred in lighting techniques. Games began using shaders to control color, light, shadows, reflections, and transparency. Thanks to these, scenes appeared dynamic and realistic. For example, in Doom 3, flashlight lighting became a key gameplay element, creating a tense atmosphere and affecting spatial perception. In Half-Life 2, artists paid close attention to detail, achieving realistic faces with expressive emotions. CGI reached a new level of simulation and physics.

Shortly after, games began adopting the language of cinema. The story became part of the experience rather than just a background element. CGI cutscenes played a key role in this, setting a new standard for quality. Studios like Blur Studio and Digic Pictures created cinematic videos with high levels of detail, enhancing the drama and bringing games closer to full-fledged films.

The Evolution of Game Graphics Toward Realism and Photorealism

The late 2000s saw the release of new computer programs that improved game graphics in terms of physics, animation, and scale. Objects in scenes were no longer static backgrounds—they responded to the player’s actions. Moreover, in the early 2010s, texture quality increased, adding more detail, realism, and immersion into virtual environments.

As mentioned earlier, the gaming industry drew inspiration from cinema. Motion capture technology, successful in films like The Lord of the Rings and Avatar, found its way into video games. A prime example is The Last of Us, where the characters’ emotions are conveyed through subtle facial expressions and movements, making them feel alive. Notably, The Last of Us Part II won two major awards—the Golden Joystick Awards and The Game Awards 2020. Animation, game design, and sound were outstanding, and fans praised the lifelike realism of the scenes.

At that time, games like Grand Theft Auto V and The Elder Scrolls V: Skyrim set a new standard. Players experienced vibrant, dynamic worlds where every detail enhanced the sense of presence.

The evolution of CGI, combined with player feedback, pushed artists toward photorealism. A key development was the introduction of ray tracing technology. Ray tracing simulates the behavior of light with maximum accuracy. Reflections, light refraction, soft shadows, and global illumination in game scenes are calculated based on physics, not imitation. Of course, creating photorealistic visuals requires more powerful PCs—but what wouldn’t you do for high-quality CGI?
