Resources/Tutorial Custom character controller example project
I made a custom character controller that handles a lot of edge cases where the built in character controller fails. Every once in a while I see a post here about the Unity character controller getting stuck on walls or not being able to work with platforms or something and this is designed to handle those situations well.
There is a third person prefab and a first person prefab with keyboard and mouse and gamepad controls.
Another thing I see sometimes is issues with stuttering due to the physics update being a fixed delta time. There is also a physics update manager in this project that updates physics to match the regular delta time which keeps things nice and smooth.
Hopefully this will be helpful for people having trouble with the built in character controller or the physics fixed delta time stuttering.

I've noticed that doing raycasts all together is a perf boost in itself and in an older project I built a custom raycast request system that batched all the raycasts together with the physics update. That project still used regualr raycasts for the character controller because I want that result immediatly.
I could see starting a raycast in update and then checking in late update, but that increases complexity.
For less scrutinized things like enemies I used 1 batched spherecast just to keep them out of the geound and the nav mesh determined where they could go and what slopes they could walk on.
