Just wanna chime in here, that I think John is merely describing that the redrawing of the background image’s new position, is slow. So the parallax effect isn’t smooth.
If understood correctly, I’m here to say +1 – I’ve in fact abandoned the parallax effect in Beaver Builder, because of the slow redrawing. Perhaps the js/css can be improved?
I tested this by deactivating cores of my CPU, and deactivating the GPU (using only intel graphics) and the less computing power, the slower the parallax bg images is redrawn.
But it’s still not scrolling smoothly when with full CPU and GPU resources available… At least not if the computer also has other tabs open, or not much idle RAM left.
So yeah, if the parallax code can be optimised, I hope you’ll consider doing so:)
Side note:
Consider adding a translate effect (text overlay fading to 0% opacity when scrolling). Neat, and it requires less computer power than parallax, and as such loads/scrolls much faster:)
