A Number of GeForce GTX Graphics Cards Will Now Support Ray Tracing

15 April 2019

You can download the new graphics driver from Nvidia in order to enable this functionality, but keep in mind that "basic RT" effects are limited to just Pascal GPUs, and the GTX variants of its Turing cards, such as the GTX 1660 Ti and GTX 1660 (as well as laptops with equivalent GPUs).

Back at the GDC 2019 in mid-March, Nvidia CEO Jensen Huang revealed that real-time raytracing technology was about to become available to a lot more Nvidia GPU owners in the coming weeks.

You'll need to download the latest Game Ready driver for your specific card to use the feature. Apart from DXR support, the update also brings Game Ready drivers for Anno 1800.

If you want to have fun with real-time ray-tracing in games - a feature that is exclusive only on RTX 20-series cards thus far - then this is good news for you. As you can see below, even the company's newly-released GTX 1660 and 1660 Ti cards offer subpar performance. This matched the RTX 2060 without DLSS but I think the resolution and settings are something you should consider when running RTX titles on non-RTX cards.

NVIDIA is hosting several images that allow you to adjust the slider, as shown above, to compare what different scenes look like with ray tracing and DLSS turned on versus having them disabled. Battlefield 5 uses ray tracing for reflections, and Metro Exodus uses ray tracing for global illumination and ambient occlusion.

Right now, Nvidia now lists seven games/demos/benchmarks with DXR support. GTX cards, even those based on Turing-class GPUs, would not include the new specialized hardware functions that enable Nvidia's ray tracing support. For cards lower than GTX 1060 6GB, Nvidia has decided they have neither the frame buffer nor the required horsepower to make enabling ray tracing at all worth it.

The situation is pretty much similar in all other tests, including Justice, Atomic Heart, and Reflections RTX tech demos, as well as the Battlefield V game, where only at medium DXR effects, you can get over 60fps on GTX 1080 Ti at 1080p resolution. It is the first time that real time ray tracing has been used for caustics.

Still, if you want to see ray tracing with your own eyes, even a Low quality implementation is better than no ray tracing whatsoever, provided the game runs well enough to play. Fast forward to August 2018 and the announcement of the GeForce RTX 2080 Ti at Gamescom, and now Reflections: An Unreal Engine Real-Time Ray Tracing Demonstration could run on just one GeForce RTX consumer graphics card thanks to the Turing architecture's RT Cores that greatly accelerate ray tracing performance. By adding the previous generation of GPUs to the mix users now have a choice, and the new demos are a big a part of the story, too.
