The WebGPU tech demo is designed to showcase advanced rendering techniques such as deferred rendering with over 400 dynamic lights, Hi-Z screen space reflections, and cascaded shadow mapping. However, users are currently facing issues, including a persistent loading indicator and errors indicating no available GPU adapters. These problems seem particularly evident on the latest version of Chrome running on Windows 11, leading to frustrations among users. Overall, while the technology promises significant enhancements in graphic rendering capabilities, the slow adoption across various platforms is a noted challenge.
