HW RT is a big deal. It sounded like devs will have to develop their own algorithms to lower the workload on the GPU or CPU when making use of the RT hardware on the PS5(Instructions on how to fill up the BVH). The BVH structures he showed are fundamental datastructures used for ray tracing workloads but the algorithms to work with the BVH are where I would have expected them to invest more in that. At least he mentioned that devs were able to use the RT hardware for reflections with minimal impact on the GPU.
