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 3DMark DXR benchmark is a test of raw ray tracing performance and wow, the 4090 delivers in spades here, offering well over double the performance of the RTX 3090 Ti. Later in this review, we test four different games with ray tracing, but this is a very promising start.
