Description
This PR introduces two new examples to compare the performance of WebGL and WebGPU renderers using a non-optimized GLTF scene. The scene consists of approximately 800 meshes and 140,000 vertices.
The goal of these examples is to provide a direct comparison of rendering performance between WebGL and WebGPU. This will help identify areas for optimization and guide further development of the WebGPURenderer.
