I don't know a lot since I have never tried running the game myself but I think it might be mainly to make zips possible on older lower end hardware. I have a 3060 and I am able to hit the 60fps cap pretty much without drops but my friend who is on a 1660s hovers around 45fps so he wouldn't be able to zip. I saw the runner wormdog using it so I would suggest asking in chat or yt comments or just asking in the dc server.
