So I started having an issue where it looked like everything was vibrating, first of all checked the post process stuff, wasn’t that, checked any dynamic settings or movable settings, wasn’t them.
Turns out, the scale of collision directly effects some sort of stepping, if you create a box with standard collision (Not bsp), move around on it, it should be fine, scale in the x and y axis by a large amount and the larger you go the more you will vibrate while traversing.
Thought I would post this for future reference for other people with similar problem.
It would be good if the engine can detect the threshold and add a subdivision equivalent to collision to ensure this isn’t an issue.
In short: Make your collision boxes smaller!
