The Riftbreaker has gotten a demo out, and it's raytraced enabled. Not only that but it's BY FAR the best showcase for RT Shadows when combined with its day/night cycle. The transition from day to night is jaw dropping when it happens. Performance is quite good as well! 75% of 4K All max holds 60 fps on an RX 6800.

(unfortunately I didn't make a transition gif yet; here's from AMD)
