💻 The start of the ray tracing craze in PC games with the RTX 20 cards in 2018
Article summary:
The year 2018 marked the beginning of a revolution in the world of PC gaming thanks to the launch of the GeForce RTX 2080 and RTX 2080 Ti graphics cards, which introduced ray tracing (Ray Tracing) into the experience of playing on a personal computer. Although the number of games supporting this technology was initially limited, it drew broad interest from the gaming and development communities, changing the graphics landscape and leading to continuous progress in hardware and software. In this article, we will discuss ray tracing technology, its impact, and the challenges associated with it in the gaming sector.
⚙️ What is ray tracing technology (Ray Tracing)?
Ray tracing is a graphics technology that simulates the interaction of light with scenes and objects in the virtual world with high precision, providing highly realistic lighting, shadows, and reflections that were not possible with traditional techniques such as Rasterization.
Ray tracing simulates the paths of light rays from their sources until they reach the eye or camera, while calculating reflections and refractions on different surfaces. This process is complex and requires a great deal of computational power from graphics processing units (GPUs).
🧠 The rise of GeForce RTX 20 cards: the beginning of this technology’s rise
In 2018, NVIDIA introduced its new “RTX 20” generation of cards, which aimed to support ray tracing in games in a practical way, through dedicated processing units called RT Cores, alongside boosting computational processing capabilities with Tensor Cores for artificial intelligence.
The GeForce RTX 2080 and RTX 2080 Ti cards took center stage, and they were the first two cards to bear the RTX name, offering dedicated support for ray tracing technology at the performance level.
🔍 The reality of game support for ray tracing in 2018
Despite the great excitement surrounding the launch of these cards, game support for ray tracing technology was limited at that time, due to:
- The need for developers to build game engines compatible with ray tracing.
- The high performance requirements, which made fully implementing the technology a challenge on hardware.
A small number of games supported ray tracing at launch, and most of them were technical demos or games that received updates adding partial support, which led to the impression that the technology was “pushing beyond the limits of the hardware” rather than being a truly used feature.
A qualitative leap started by the RTX 2080 in the world of gaming, even if the beginning was modest
🚀 The technology behind RTX 20 cards
The new cards used:
- RT Cores: dedicated cores for ray tracing calculations that facilitate realistic ray tracing tasks.
- Tensor Cores: to enhance AI performance used in technologies such as DLSS (Deep Learning Super Sampling) to improve performance while maintaining image quality.
- Faster memory and more advanced CUDA cores.
This set of technologies made it possible to achieve a practical and robust ray tracing experience in games in the future.
🎮 The development of game support for ray tracing after 2018
Since the launch of the RTX 2080, game support has gradually expanded, especially with major players in the market such as:
- Control
- Metro Exodus
- Battlefield V
Many games began adding ray tracing options for a deeper experience of realism and more impactful graphics.
NVIDIA and AMD also helped develop software tools and technologies to support ray tracing on a broader scale, while game developers continued to improve performance.
🔐 The technical challenges of ray tracing technology
Despite the progress, there are technical obstacles such as:
- The need for intensive computational power, which places a burden on the GPU and affects frame rates (FPS).
- Programming complexities involved in integrating and tracking ray tracing within game engines.
- High memory and storage requirements for complex light-tracing patterns.
Solutions such as DLSS used artificial intelligence to reduce these burdens and accelerate performance, making the technology more viable for adoption in the future.
Ray tracing is not just a design enhancement, but a real revolution in graphics quality
☁️ The impact of ray tracing technology on the future of computing and technology
NVIDIA’s focus on supporting ray tracing, as it did with the RTX 20 cards, opens many doors:
- Developing cloud computing to provide high-quality games via streaming (Cloud Gaming) with high-definition ray tracing.
- Increasing reliance on specialized processors that combine graphics processing and artificial intelligence.
- Driving innovations in areas such as virtual reality (VR) and augmented reality (AR), which require advanced lighting quality and realism.
🔧 Technical tips for gamers and game developers
📌 For gamers:
- Make sure to update your graphics card drivers to support ray tracing and new AI tools.
- Use ray tracing settings moderately to ensure a balance between performance and graphics quality.
- Pay attention to the device’s power requirements and heat when enabling these technologies.
📌 For developers:
- Use game engines that support ray tracing such as Unreal Engine and Unity.
- Adopt AI technologies for dynamic performance optimization.
- Follow updates to graphics libraries and GPU technologies to make the best possible use of them.
Enhancing the gaming experience goes through leveraging every modern technology such as Ray Tracing and AI
🔚 In the end
The launch of ray tracing technology with the GeForce RTX 2080 and RTX 2080 Ti cards in 2018 was an important turning point in the world of PC gaming. Despite the limited game support at the time, this step laid the foundation for what is now known as the modern graphics revolution.
The move toward more realistic graphics and precise lighting models, in addition to harnessing artificial intelligence technologies, makes the future bright for gamers and developers alike.
Technology summary:
The ray tracing technology launched with the RTX 20 cards made realism in PC games a permanent goal, and today it is an integral part of the technological evolution of the gaming industry.
