Ray Traced Reflections Ray Percentages Comparison
In the above shots, you can see the impact of ray count on image noise (without DLSS or TAA) with ray-traced reflections enabled. As you can see, the noise intensity increases quite significantly below 50%. There’s a notable difference even between 70% and 100%.
In the case of shadows, the number of shadow-casting lights doesn’t affect the quality by that much unless you dial it down all the way to quarter resolution. At 50% or half resolution, only a few select shadows disappear compared to full-resolution RT Shadows.
Finally, there’s the matter of performance. Looking at the charts, you can see that even the quality preset of DLSS improves frame rates by more than 60%. Falling back to performance nets you more than twice as much performance while ultra-performance pushes the gains past the 2.5x mark.
