What exactly is Ray Tracing and why does it matter?

Ray tracing is a rendering method that can generate amazingly realistic lighting impacts. The system utilises an algorithm that can trace a path of light and then work out how the light interacts with an object giving you an ultra-realistic depiction of that object in the space.

In its purest form, ray-tracing is becoming more and more realistic, with how an object affects that light is why it’s becoming more lifelike. The main benefit of the hardware architecture that is designed with ray-tracing processing built in is the opportunity to make these light traces and calculations.

When we talk about “light”, we also talk about colour. With the way that light interacts with objects, it produces colour depending on what colours are absorbed and which are reflected on the object. So with this in mind, with ray tracing, you can create almost lifelike images that you can barely tell are computer graphics.

The new benefits of cards like the EVGA Geforce RTX 2080 with the Turing micro-architecture, is there is now a dedicated hardware platform to perform these calculations. Turing is the code name for the GPU micro-architecture developed by Nvidia as the successor to the older Volta architecture. We know that some GTX cards will support Ray tracing but at the cost of resourcing, which still makes the newer RTX line a more attractive purchase for serious gamers.
