    Not great on IE either but perfectly smooth on Chrome.

    It may not be that evident but more than a few of the flames don’t get faded out properly, instead at the end they instantly disappear.

    The animation isn’t that intense, only six images get transitoned over a small part of the screen. I’ve tried all possible tricks to improve it (all related to hardware acceleration) but it seems inherent to the browser to not handle it properly.

    Any ideas welcome.

    Okay, this is just weird. I just noticed that when I have Chrome open with the same pen, the one on Firefox suddenly runs smoothly.

    Anybody else even seeing what I’m referring to? Might be machine/OS related (although I doubt it). Could be good to rule that out.

    Not a clue how to solve it, even changing browser config settings has no effect.

    Firefox 66.0.5 Runs perfectly

    Okay, thanks for letting me know. All info is appreciated.

    Opening Chrome has no influence on IE’s performance but it definitely has an impact on Firefox, which I am rather amazed at.

    I’m using onboard graphics, it’ll be interesting to see what adding a graphics card does.

    Another detail – when I do a performance check in developer tools (perfectly fine at maximum frame rate), it suddenly also runs smoothly. And it even stays that way after recording has stopped. I’m baffled.

    Installed a graphics card recently and the animation is now smooth.
