NVIDIA has released two new RTX demo videos showcasing the latest technology. In the first video, an Unreal Engine 4 attic scene is used with the ability to toggle on and off ray-traced reflections, shadows and translucency to see the impact the features have on the scene. You can also see how RTX Global Illumination adds dynamic range to the scene with multi-bounce indirect lighting. Finally, they demonstrate how DLSS can be used to boost the frame-rate while maintaining a high resolution. As well as the video, can download the demo as a standalone application from the NVIDIA developers website.
In the second video, we are shown a demonstration of RTX Direst Illumination as it casts realistic lighting in dynamic scenes that require computing shadows from millions of area lights. Until recently, this hasn’t been possible in video games in real-time.
