Path tracing is inefficient compared to Ray Tracing. This is just a DxR(Hybrid Ray Tracing) benchmark. We won't see fully Ray Traced game until video card compute power triples. Even than hybrid ray tracing still looks better than just a standard game.
DXR will initially be used to supplement current rendering techniques such as screen space reflections, for example, to fill in data from geometry that’s either occluded or off-screen. This will lead to a material increase in visual quality for these effects in the near future. Over the next several years, however, we expect an increase in utilization of DXR for techniques that are simply impractical for rasterization, such as true global illumination. Eventually, raytracing may completely replace rasterization as the standard algorithm for rendering 3D scenes. That said, until everyone has a light-field display on their desk, rasterization will continue to be an excellent match for the common case of rendering content to a flat grid of square pixels, supplemented by raytracing for true 3D effects.
