As promised at GDC, Nvidia has released its DirectX Raytracing (DXR) drivers for GTX cards today—grab them here. Okay, so they're not just for GTX cards, and they're Game Ready for Anno 1800, but DXR on GTX is arguably the highlight. The driver revision also sees a large jump, indicating this is a major update—Nvidia has gone from version 419.67 to 425.31.

There's plenty to discuss, but testing ray tracing performance on GTX cards will require some time—more than I can do in just a couple of hours. Nvidia has provided its own internal benchmark results, some of which I've included below. As usual, take these with a grain of salt, but most of the numbers appear to be in line with what I'm seeing. I'm using a different testbed (overclocked i7-8700K instead of i9-7900X), and my results so far are a bit higher than Nvidia's for the faster RTX cards like the 2080 Ti. But the GTX cards are much slower with ray tracing, so the CPU used won't matter much there.
