If you have a nvidia GPU, then it may well be the fault of the latest drivers (390.25), which have been buggy, and it's especially notable under Chrome/Chromium (video/audio stuttering, problems with vsync, general slowness, high CPU usage, etc..).

Arch has a recent thread about it: https://bbs.archlinux.org/viewtopic.php?id=234241

I got solid 60FPS using Firefox Developer Edition on Arch, it would be interesting to see what the issue is for you (might be hardware, I'm running a Vega.)

Between 30 and 50 fps on Firefox 58, on Kubuntu, on a slow-ass Intel Celeron 3205U (1.50ghz) laptop.

Amazing. Just amazing.

Re: Vega — I think it's pretty clearly some sort of software issue — other people are having no trouble with mobile/embedded/iGPU hardware. This machine has an Nvidia GT 610 in it, which isn't high end gaming equipment. But it should be adequate for this demo.

You might wanna try activating the #ignore-gpu-blacklist in chrome://flags

But be aware that it can cause some collateral damage like broken websites (if you have it and it bothers you, you can simply turn the flag off again). For example, with my Haswell Intel GPU I had never any problems, but with my Radeon it results in some strange textures on some website. FF has no problems with neither of them.

Same here, 3 to 5 fps on Chrome and a consistent 60 fps on firefox 58. There's definitely something wrong with Chrome for linux. Try the Stripe docs page https://stripe.com/docs/api#error_handling , same issue. Buttery smooth scrolling on firefox but unusable on Chrome.

Anything under 10fps on a modern machine is almost certainly not benefitting from GPU acceleration.

Unless you try running a demanding AAA game in 8K resolution :D

60 FPS + negligible CPU on Chrome OS with Haswell though, interesting.

Yeah, clearly Haswell (+ my GPU) is capable of much more. Just not being utilized well.

I get ~60 fps on Broadwell Xeon, Xubuntu, Chromium, and a 1060 GPU.
