What are normal framerates to expect here, with working graphics drivers on a modern laptop with Intel embedded graphics? I'm asking because I have the suspicion my Firefox is not using hardware acceleration, at least not properly. In my case, it reaches roughly 30 fps.

I'm barely getting 12fps on a 2016 MBP with latest Chrome stable.

  Author here. Are you getting any warnings? Does it say it is using WebGL 1 or 2 on the left side? I am getting 60 FPS on Windows Chrome 64 with WebGL 2 on a 5 year old Radeon 7870 and it's mostly idle. I have implemented fallback to WebGL 1 for other platforms than Windows, because there were bugs that I don't have the platforms to test on (I tested on Linux in VMWare, but only WebGL 1 as WebGL2 is blocked on VM), and that path is not very optimized. Still I was getting 60 FPS on Linux Chrome in a VM as well. Firefox in Linux VM was slower though, at 30 FPS or so. There might still be optimizations I can make and I could add more configuration settings for texture sizes. How does http://madebyevan.com/webgl-water/ http://madebyevan.com/webgl-water/ look in comparison? Is it smooth? Most of my water code is copied from his version. What's your OS and browser?

    I am getting only 30 FPS, Error: WebGL: texImage2D: Conversion requires pixel reformatting. Firefox 52.6 ESR on Windows 7, on a beefy ThinkPad W541.

      I checked the specs comparison at (https://www.videocardbenchmark.net/compare.php?cmp%5B%5D=2623&cmp%5B%5D=324 https://www.videocardbenchmark.net/compare.php?cmp%5B%5D=262...) and it says my card is about 4 times beefier than yours even if it is a year older, so maybe 30 FPS is expected. Thanks for the error report on texImage2D though. I will make an issue on the repo.

  For me it's slower on chrome too, FWIW.

I have an Intel iGPU plus a mobile nvidia GPU -- nvidia drivers take care that most things that don't explicitly ask for the nvidia card (games, machine learning) run on the iGPU to keep power use down. The iGPU is the one on the i5 7200u, and gives 25fps.

For Firefox, go to about:support and scroll down to the graphics section. Also make sure "use hardware acceleration when available" in the performance section of preferences is enabled. For Chrome, go to chrome:gpu For any of them, note that Windows may update the GPU driver a bit after startup and it disables GPU acceleration of open browsers until they're restarted.

  Thanks for the hint, though I'm facing the issue on Ubuntu only (on Windows, everything seems fine). I think I've made the same investigation before, but to no avail. HW_COMPOSITING says "unavailable by default: Hardware compositing is disabled", and OPENGL_COMPOSITING something similar. This corresponds with my experience of jumpy scrolling and Youtube making the the fans go berserk. But apparently, WebGL isn't affected by this and performs okay.

    If you use KDE, try disabling compositing with Shift+Alt+F12.

      I'm on Unity (and probably Gnome Shell sooner or later).

Same here, I am on a laptop that changes between Intel and NVidia dynamically.
