Only three games use NVIDIA RTX extensions -- everything else is DXR

In an interview with WCCF Tech, NVIDIA's Brian Burke revealed there are just three games that do not use Microsoft’s DirectX Raytracing (DXR). The vast majority of RTX-supported titles use an implementation of DXR so these games should be compatible with AMD's soon-to-be-out Radeon RX 6000 series.

W Burke said only Quake II RTX, Wolfenstein: Youngblood and JX3 use NVIDIA-made RTX extensions. This is because these games use the Vulkan API and at the moment the Vulkan Ray Tracing extensions aren't ready yet.

NVIDIA says there's nothing stopping AMD from making its own Vulkan ray-tracing extensions. Or alternatively, AMD could use NVIDIA's Vulkan ray-tracing extensions. Intel is reportedly considering to use NVIDIA's RTX extensions for Vulkan for its upcoming Xe-HPG GPUs. The NVIDIA RTX extensions are open for other manufacturers to use, but for obvious reasons, AMD isn't inclined to adopt it.

Both Nvidia and AMD GPUs with ray-tracing acceleration will be able to use the current industry standard, which is Microsoft’s DXR. This clarifies previous confusion around Cyberpunk 2077, which was incorrectly claimed to only support ray tracing on Nvidia GPUs, but as it uses DXR, ray tracing will work on AMD’s RX 6000 series cards. Nvidia also claims there is also nothing stopping AMD from creating its own RT-extension for Vulkan while the Khronos Group finalises its official extension for industry-wide use.
