GeForce RTX 30 vs. AMD Radeon RX 6000 Series Vulkan Ray-Tracing On Linux
The Quake II RTX performance was quite low on the Radeon Software for Linux 21.30 driver build.
Ray-Tracing In Vulkan is an open-source demo/benchmark of Vulkan RT capabilities. It depends upon the scene, but in some scenarios the RDNA2 ray-tracing performance is very good against NVIDIA's RTX 30 series and their latest proprietary driver.
But in other scenes, the RDNA2 performance was struggling like with the Quake II RTX benchmarks.
