I got negative value for the GPU time while checking last commits/examples update on threejs release164.

I know webgpu is fast but this seems too fast haha :D

Hi @RenaudRohlinger , do you need help to investigate this issue and calm down the m3 max ? :D

The calculation from here seem correct : https://webgpu.github.io/webgpu-samples/?sample=bundleCulling

Even with my M1 Max Pro and iPhone 12, I am unable to reproduce this issue, nor the one described in https://github.com/RenaudRohlinger/stats-gl/issues/11.

Without encountering these bugs myself, it's difficult for me to diagnose and fix the issue. Could you clarify if the problem seems to originate from the Three.js side or the stats-gl side?

You can try logging the values with console.log(gl.info.render.timestamp) in the examples to confirm this. /cc @Makio64.

This console.log return me : gl is undefined I cloned three.js and changed the example of batch adding some log on stats.gl but its always null Your example https://stats.renaudrohlinger.com/ works as expected ( bellow screenshot )
