Hello,
I am getting an drop of 10-15 FPS as I add box or any collider to mesh. Is this normal or I am missing something.
Thanks
No it’s not normal. Just adding a box collider to a object should not make a noticeable difference… unless there is something in your scene or in your scripts that as a result of the collider cost a lot.
What else is in the scene? What else is on the object that receives the collider?
Check the profiler, it should give you a break down of the cost of each script or process. If it is Unity’s physics you will be able to tell.
