Microsoft's DirectX 12 Ultimate brings ray tracing effects to more

More efforts are underway to bring ray traced visuals to more of your games. Microsoft has introduced a DirectX 12 Ultimate framework that makes ray tracing and other visual effects both more efficient and more flexible. A new inline ray tracing technique gives more control over the lighting effects that make more sense for certain games, GPU shaders can invoke ray tracing without talking to the CPU and streaming engines can more efficiently load ray tracing shaders as you roam around. Your games won't demand as much from your system as they did before.

Ray tracing will come to more games with a new Vulkan SDK
