How do I animate a 3D background?

Hi!

I am new with Construct 3 and I'm trying to make a few simple games for a website.

This is my problem, I'm trying to animate a background by looping a set of images, a GIF, video or whatever method would be best. The idea is to give a 3D feeling to the background instead of a flat surface moving.

To explain better, he's a video of the image sequence;

So here's the problem, I can't tile these images because of their difference on the left and right area (because of the 3D perspective). I tried using a sprite animation but it's laggy even on a PC.

Looking for possible options to make this work better, so far the sprite animation just looks bad.

I would truly appreciate any help or suggestions : )
