Xvfb - is it possible to improve image quality?

Question

linux

Good day colleagues. I am writing a node.js script that takes html animation and renders a video from it. When run on a local machine, it produces high-quality 1080p 60fps https://www.youtube.com/watch?v=z2mcrlOE_ss
But I need to run this business on the server - I tried to wrap it in a docker container, put Xvfb in it and run it in it. The same code produces terrible video quality (fps is far from 60) https://www.youtube.com/watch?v=GEx0DGegpB0
Tell me, is it possible to emulate a display on the server that will give out 60fps? Perhaps you should use another utility, or some options for customizing Xvfb (I looked at the documentation, I found only screen resolution and dpi there)
