DirectX Raytracing feature test Real-time ray tracing is incredibly demanding. The latest graphics cards have dedicated hardware that’s optimized for ray-tracing. The 3DMark DirectX Raytracing feature test measures the performance of this dedicated hardware. Instead of using traditional rendering techniques, the whole scene is ray-traced and drawn in one pass. The result of the test depends entirely on ray-tracing performance. The DirectX Raytracing feature test is available now as a free update for 3DMark Advanced Edition from Steam and the UL Benchmarks website.
