It doesn't work on chrome on linux for me. But my android phone (LG) and Windows Edge seem to run it fine.

Does it really do anything on mobile?

Anyone got some example results they can share with us, including hardware/OS/software you're running and what kind of speed up was found?

It works on my Note 3, but not on my S7. The N3 results are about 1.5/3.0 for me. Though wildly varying between runs.

Edit: It works on my windows PCs (even in a qemu KVM instance using the std vga, but of course the emulated GPU is slower). However, it doesn't seem to like any browser on linux.

I'm confused -- there's a section mentioning a benchmark, but I can't find the results anywhere on the page. Chrome 54 on macOS 10.12.1.

There are sections for "PURE JAVASCRIPT" and "JAVASCRIPT & TURBO.JS", but they only display a triangle/circle illustration.

Open the console and look for errors?

I thought about it, but there's not really much I can do.

testData is undefined on line 28 of benchmark.js.

Sounds like WebGL didn't initialize. Do other WebGL demos work in your browser? If yes, I'd report this issue to the dev.

weird:

> Ah snap! There was no error compiling the test kernel or running it, but the numbers don't check out. Please report your browser (+ version) and hardware configuration to us, so we can try to fix this. Deviation was 0.673000000262012.

Latest Chrome on a macbook air. Looks like at least one other person has had this issue, I'll report my experience as well. https://github.com/turbo/js/issues/1
