On the images bellow you can see my sphere bouncing without CCD on the left, and with CCD on the right to prevent tunneling with faster velocities.
The ground surface is the same on both examples and it's the same sphere.
The restitution values are the same on both examples, but with CCD the sphere looses momentum after collision.
I have checked the sphere velocity on collision and with CCD enabled, it's much lower than without.
This might be explained from the force bullet is applying to prevent penetration.
Is there a way to improve the sphere collision response with CCD?
I'm trying to avoid setting an higher FPS on the simulation.
