Nick S. said: Hi Memm, thank you for the kind words! I'm sorry you're experiencing lag with them; I've asked to see if there are any news regarding animation lag and if there's anything users can do to improve the situation while Roll20 works on a fix. While not everyone seems to have the problems, it's widespread enough that it should be handled quickly by Roll20 (one could hope). There's also a known bug with audio + animations that drastically worsens the experience. After Roll20 re-encodes the animations they tend to be around 1mb each (and were ~10mb max before that), so in theory they shouldn't be causing such cpu spike; I'm hoping they can fix the platform soon so we can enjoy them properly. I'll let you know if they mention any fixes. In the meantime the only thing that comes to mind that might help (besides no audio, if you're being hit by that bug) is hardware acceleration, but that's usually enabled by default on most browsers. Worst case scenario, the Layer Up update will be ready for testing in around a month if they keep to their schedule. It will be a new layer that supports animations with areas of effect and hidden parts made specifically for weather, so hopefully they'll have the solution by then. I'm sorry I don't have better news yet, but there's not much more I can do but wait for Roll20 at this point :/ Yeah, unfortunately the problem is with the way Roll20 handles animations. Normally my CPU usage is -- even in a campaign with 5 years worth of stuff and large maps filled with assets -- around 5-10%. However, as soon as I add one 25x25 weather animation the CPU usage goes all the way up to 45%. Add in another and the CPU usage is ~80%. Third one clogs the computer. That's just bonkers. That said, these weather animations are superb. Shame that Roll20 doesn't work well with animations :/
