I think there is a lot of potential in this glitch, you get a huge speed boost right after clipping into the ground. I tried mashing dash and was able to maintain that speed for a screen length or so, but I wasn't able to reproduce it reliably. If you nail the trick first try you can skip acorn maker without slowing down at all.

here it is used to skip the acorn maker: https://gfycat.com/gifs/detail/ElasticIdealisticArcherfish right before the acorn maker on another grass thing: https://gfycat.com/gifs/detail/IncompatibleDependentAsiansmallclawedotter right at the beginning of forest follies: https://gfycat.com/gifs/detail/GrizzledVillainousCommongonolek

I was only able to clip into the dirt/grass platforms on forest follies, I think it may be a bug with that piece of terrain.

If you want to see what kind of FPS you'll have before buying the game you can download the demo at http://www.croteam.com/talosprinciple/

I benchmark 200 fps on minimum settings in the demo and all the tricks work fine on my machine.

A lot of the tricks are impossible for me on certain video settings, I think the physics are some how related to your FPS or something like that. Maybe it's a similar issue for you? I had to screw around for a couple hours in the settings before I could get the paint bucket skip in B to work

Yeah, it also broke that section for me as well. You can use a single box to climb the tree directly across from the blue laser source, and then jump on the wall from there in about 15 seconds though.
