Nvidia GeForce RTX 2080 Super Video Card Review

Port Royal is the first benchmark dedicated to real-time Ray Tracing.  You can use Port Royal to test and compare real-time ray tracing performance on any graphics card provided you are running the correct version of Windows 10 and Microsoft DirectX Raytracing.

Unlike with other 3DMark benchmarks Port Royal is only a single scene and focused completely on GPU performance.

Sadly I only have a single RTX card in the Hardware Asylum Labs so you will only get a single score.  At least until you hit the Overclocked section.
