DXR seemed far more CPU and memory demand require CPU with 6C/12T Core i7 8700 and above or 8C/16T Ryzen 7 2700 and above, RTX 2070 and above and 16GB RAM than DirectX 11.1 recommended system requirements.
I hope to see first Ray Tracing game in November, Battlefield V could be the first Ray Tracing game. Still no news when Shadow of Tomb Raider patch will support Ray Tracing after patch 5 issued on 31 October.
