The 3DMark DirectX Raytracing Test requires a graphics card with drivers that support DirectX Raytracing (DXR) Tier 1.1.
If you have a compatible card, first check that you have the latest drivers.
If you are certain your card should support DXR Tier 1.1, and you still see this error message, try wiping your graphics drivers and then reinstalling the latest drivers for your graphics card.
AMD
All AMD Radeon RX 6000 Series graphics cards support DXR Tier 1.1.
Older AMD cards do not have DXR support and cannot run this test.
NVIDIA
All NVIDIA GeForce RTX 20-series, RTX 30-series and professional RTX-series graphics cards support DXR Tier 1.1.
While some older GeForce GTX 10-series cards have DXR drivers and can run Port Royal, these drivers do not have DXR Tier 1.1 support.
