What is Real-Time VFX in Video Games?

Real-time VFX is an incredible visual tool in gaming that helps create a sense of immersion, set specific tones, create visual feedback for players, and acts as a communication device from the game to the player. From incredible superpowers to foggy urban streets and roaring fires, game VFX’s role is not to be understated and is growing more potent with each passing year.

Real-time VFX for games is one of Magic Media’s cornerstone services, with which we have years of experience working on a diverse range of projects, from indie to AAA. Let’s uncover what game VFX is and how it changes game development’s possibilities.

The Roles of Real-Time Game VFX

Real-time game VFX fulfills several roles. It plays an important role in player communication so that they inherently understand what is happening throughout their gameplay experience. In most games, certain effects mean specific things universally. Blue or white magical effects in fantasy games often represent healing, whereas red could mean a damaging effect. This also applies to more common effects such as fire, water, wind, and more, where we intrinsically understand their effects because they’ve been well-communicated visually.

Real-time video game VFX also plays a significant role in immersing players in the game world. Some horror games, like the classic Silent Hill 2, make plentiful use of real-time VFX to create a foggy, unknowable atmosphere, which helps dial up the game’s palpable sense of tension. Magical worlds like the realm of Vanaheim in God of War Ragnarok use real-time VFX to create an extraordinary and other-worldly atmosphere, with multicolored visual phenomenons that would be impossible to see in real life.

Real-Time Game VFX Techniques

Several different techniques are used to create the desired real-time game VFX. Particle systems are used to create effects such as smoke, fire, sparks, and magical spell effects. Particle effects are defined by numerous small particles whose properties can be adjusted to generate an effect. Their size, color, velocity, lifespan, and much more can be adjusted to produce various effects. These robust options make particle effects one of the most powerful techniques in real-time video game VFX.

Shaders are programs that draw on a system’s GPU to manipulate objects in real-time. Pixel shaders, for example, are GPU-based programs that control the color and lighting of individual on-screen pixels. They can be used for dynamic lighting effects, reflection, and refraction, and are only limited by the imagination of the developers creating them.

Responsive Real-Time Game VFX

Perhaps one of the biggest strengths of real-time video game VFX is its responsiveness to player actions. Inflicting damage upon enemies is a common example, where blood effects are produced in response to the attack. Preparing magical attacks is often accompanied by appropriately colored effects emanating from the player or their weapon of choice. Enemy weak spots, a common combat gameplay mechanic, will often glow with a particular color and visually respond when attacked to communicate with the player they successfully struck a critical spot.

Gamers, whether experienced or not, will more often than not be able to intuit the results of their actions in games with high-quality real-time game VFX. Though these communication devices formed in real-time VFX might not be overly noticeable to some, especially regular gamers, the absence of it could have a profound effect on one’s ability to understand actions and their results in games. It’s critical to design real-time game VFX with practicality in mind as well as its aesthetics. Its role is more critical to player experience and engagement than many realize.
