Here we revisit Control, this time with ray tracing effects set to High.

Turning on ray tracing effects in Control brings us the single biggest gain for PCIe 4.0 vs PCIe 3.0 from across all of our testing today – an improvement of 5% at 1080p. That was when comparing just the AMD test systems, but the 3900XT with PCIe 4.0 is still 2% faster than the 10900K at 1080p.

The margins shrink at 1440p, but we still see a 3% benefit to PCIe 4.0 when tested with the 3900XT. Lastly, the figures at 4K are essentially identical regardless of CPU or PCIe bandwidth.
