CUDA Ray Tracing 2x Faster Than RTX: My CUDA Ray Tracing Journey
A showcase of my projects and portfolio.
While there are many contributing factors, one likely explanation—pointed out by Tanguy Fautré (GPSnoopy) —the author of RayTracingInVulkan, shared his insights on why procedural ray tracing may underperform on NVIDIA RTX GPUs: Supporting this theory, RayTracingInVulkan consistently benchmarks better on AMD cards, such as the Radeon RX 6900 XT, which perform BVH traversal using compute units rather than dedicated RT hardware. And with the help of Nsight Compute, I wasn't just reading theory—I was hands-on, exploring real bottlenecks, discovering how latency hiding works, learning about warp scheduling, cache behavior, and so much more.
