CPU or GPU ray-casting ?

this may not be the right place to ask for my question.
I have the same BEPU physics game which does a ton of ray-casting at 10Hz, for which I am doing it in a separate thread while locking on "space.BroadPhase.Locker".
My desktop is i7-4790k and Geforece GTX980. As soon as I turn on ray-casting, the draw rate drops from 60fps to 18 fps. Surprisingly, i tried it on my 4 years old laptop, i7-2670QM and Qurado 1000M. The laptop is doing really smooth at 60fps draw rate.
I guess my desktop has some funny issue. How does the ray-casting work behind the scene? Is it software based ? Or GPU plays an important role?
