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. (UL).
The RX 6600 XT doesn't do so well in the 3DMark DXR Featuretest, but once more we're only looking at minimal differences between the Pulse and Gaming Pro OC. It is the latter card which comes in just about the fastest of the two, but a difference of 0.09FPS is all there is.
