Hah! I was just typing more or less the same thing, and the new post indicator popped up with your message before posting. I will post my same-ish response anyway. : PConsidering that the Radeon RX 580 is about 50% faster than the GeForce GTX 680 you can not in any meaningful say compare the Xe-HPG with either of them.
So, you expect an 8+ year old GTX 680 to meet the recommended requirements for Raytracing? >_>I suspect the requirements derive from support for the DirectX 12_2 ray tracing, which MSFT apparently leaked already includes for Xe-HPG.
