To achieve real-time framerates, it was necessary to partially scale back reflection quality during camera movement and the amount of geometry visible in reflections. Tracing rays for every frame was resource-intensive and required a great deal of optimization work in other areas. It was, however, computationally taxing to run so many calculations in real-time. As this is fundamentally similar to how light behaves in real life, it can achieve amazingly realistic results.

Ray-tracing techniques emulate this effect: an algorithm simulates light rays, tracing them from the imaginary eye, or camera, to the light source. Everything we see in the real world is a result of light interacting with the objects in our view. In contrast to many game engines, we here at Enscape already realized the value of showcasing ray-traced lighting and reflection calculations and have done so in our real-time engine.
