The planet snaps around when you move with your mouse, it's pretty jarring.

Generally even with WASD I do notice a little bit of delay too, but maybe that's just me being picky

Please don't create new threads for known issues. This has been reported 4 times on this forum alone now, and is mentioned on the front page.

I apologize. It's frankly easy to gloss over the information since the mod is pretty straight forward

I recommend having a FAQ at the top of the page before it gets overwhelming. I see in one post you linked to try disabling the parallax, I'll try that.
Thank you for your patience.
