It seems that the performance of webgpu has not improved much compared to webgl.Do I need to set some parameters to achieve the expected performance？

I’m not sure to understand what are the numbers we can see in the screenshots… For WebGPU related optimizations, you can have a look at:

About webgpu vs webgl2 rendering performance

See Render performance - #2 by sebavan for more context about WebGPU performance compared to WebGL. However, so much difference between WebGPU and WebGL is not normal, are you able to setup a repro in the Playground (or somewhere else)?

Why WebGPU backend is slower?

See the current status of WebGPU implementation and words about performance here: WebGPU Status | Babylon.js Documentation The problem is that there are still API calls to the browser and those are taking time. In WebGL2, with VAO, you have a single call to setup the vertex and index buffers. In WebGPU you have a call to set the index buffer and one or more calls to setup the vertex buffers (on average 3 calls if you have position, normals and uvs). In addition to these calls, you need to call s…
