Wow, this is extremely impressive. Usually when I run a WebGL demo, my fans start blasting, but my machine seemed to handle this fine.

There's a lot of frames where you are not doing anything, so the image doesn't need to be updated, unlike most games where you always need to be refreshing the screen. Also, I believe that power management for webGL in general is/was quite bad. If I recall correctly, it didn't automatically adapt GPU power usage to the application, but rather it ran on a fixed power level. Maybe I'm wrong or misremembering, though; it would be great if someone else with more knowledge on the topic can give more details.

  The biggest issue is that a lot of GPUs are blacklisted by browser vendors to force software rendering due to bugs in the GPU drivers that might cause security or overall software reliability issues. And a lot of those GPUs are AMD GPUs. And a lot of those AMD GPUs are in MacBooks. Thus why a lot of MacBook users complain about WebGL stuff pegging their CPU and kicking in the fans.

    Do you have a source for that? (And maybe a list of GPUs that are blacklisted as well, so I know what to look out for with some customers?)

      Interesting. Found this on a quick search: https://www.khronos.org/webgl/wiki/BlacklistsAndWhitelists https://www.khronos.org/webgl/wiki/BlacklistsAndWhitelists And the more detailed list for firefox (though only NVIDIA and Intel GPUs on MacOS are reported to be disabled for security issues): https://wiki.mozilla.org/Blocklisting/Blocked_Graphics_Drivers https://wiki.mozilla.org/Blocklisting/Blocked_Graphics_Drive...

        For the first link > This page was last edited on 3 June 2015 For the second link > This page was last modified on 9 March 2016 There's no way that I'm aware of to find the complete black/whitelists of each browser. The only way I've been able to figure it out before is to disable the blacklisting and see how performance in a WebGL app fairs.

Yeah, I don't even have a graphics card in this laptop and it handled it fan-less the entire time with a smooth framerate. Seems very well made.
