I didn't know what Construct was so I went to the homepage for clues. That intro spinning cube demo runs at a solid 4 fps with graphical glitches on a not exactly slow phone (Pixel 7), give or take, and is a quite terrible introduction for a "Cutting-edge technology that runs right inside your browser like magic."

Then again the entire section on "game engine performance matters" only compares the performance of "JavaScript" (V8? Safari? Who knows!) vs. Game Maker Language and doesn't at any point compare anything about the performance of the actual game engine.

But it is cool that they're switching to WebGPU. Should make native app ports more viable to drastically improve performance and resource utilization
