Nvidia’s RTX cards could create a breakthrough for eye-tracked rendering

During the presentation of its GeForce RTX 2080 graphics cards last week, Nvidia spent most of its time on ray tracing. This is the high-end light modeling tech that could bring a new level of realism to games. But these new cards can do more than just ray tracing. One of the other potential standout features is variable-rate shading, which is a powerful feature that is an important prerequisite to another technology called foveated rendering.Dynamic foveated rendering is a process that only fully renders the part of the screen you are looking at. Everything outside of that circle of focus is only as detailed as your brain needs to convince you it is real. This is beneficial because it saves the graphical horsepower of a computer only for the part of the image that matters, and all of the power that foveated rendering saves can get put back into making the focal point look even better.
