Here are a few posts related to WebGPU perf vs WebGL:

• Render performance - #2 by sebavan
• Why WebGPU backend is slower? - #3 by Evgeni_Popov
• Why WebGPU backend is slower? - #5 by Evgeni_Popov
• 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？ - #2 by Evgeni_Popov

Especially when doing a scene heavy on GPU particles, I was supper surprised to see webGL just hands down out performs the webGPU engine in this case.

It would be nice to have a repro, because in our testing, the compute shader version used in WebGPU was faster than the feedback buffer implementation in WebGL.
