Nvidia VXGI and RTX Hardware

Just a general question regarding VXGI and the new RTX cards. Will VXGI benefit from the RT cores of the new RTX lineup to increase performance, or will we need to use RTX specific tools to take advantage of them? I am developing a game in UE4 with VXGI, and if it will improve performance by using RTX, that is even better. VXGI 2.0 is already a massive improvement. Thanks!
