Unity Collision Cheat-Sheet - Discrete vs Continuous

Each collision mode offers a unique collision mechanic. Knowing which one to use is key for solid gameplay and performance.
Discrete is the most performant option and should be used whenever possible. Calculations collisions each fixed step.
Continuous uses a sweeping algorithm to guarantee collisions from a linear motion, but is quite a bit more expensive than discrete and only hits static colliders (no RB).
Continuous dynamic is the same as continuous, but hits dynamic colliders (and is more expensive).
Continuous speculative creates a bounding box around itself and its next projected frame position according to its current linear and angular motion. Anything caught within will collide.

    A fun trick I like to use in some instances is stretch the projectile's collider according to its velocity. This way it still detects collisions at high speeds on discrete mode! :)

    Scale a collider is costly iirc. Maybe the cost is higher than the benefit.

    Nice! I have wondered about this for a while. There are so many Unity options that have no explanation tips, you could make a dozen videos like this easily, and I'd watch every one of them. By the way, you are mentioned in the Credits section of the game I am making, for all your great tutorials. Thanks!

    For the problem of ghost collisions with rotaion in speculative mode one solution that I can think of is to lag the collider of the rotating object based on its speed, so that when it ghost collides the actual mesh would be leading the collider.
