You could also try changing the fixed time step for physics. The smaller this value, the more times Unity calculates the physics of a scene. But be warned, making this value too small, say <= 0.005, will likely result in an unstable game, especially on a portable device.

The script above is best for bullets or small objects. You can manually force rigid body collisions tests:

public class example : MonoBehaviour {
    public RaycastHit hit;
    void Update() {
        if (rigidbody.SweepTest(transform.forward, out hit, 10))
            Debug.Log(hit.distance + "mts distance to obstacle");

    }
}
