NVIDIA latest driver update enables Ray Tracing for GeForce GTX cards

The GTX GPUs that support the new Ray-Tracing technology update are GeForce GTX 1660ti, GTX 1660, Titan XP (2017), Titan X (2016), GTX 1080ti, GTX 1080, GTX 1070ti, GTX 1070, GTX 1060 6GB and the laptops that are equipped with equivalent Pascal and Turing-architecture GPUs. To make it simple, the workload on processing the ray tracing increases with the number of rays involved.

The new DirectX Raytracing drivers are available now to download, and support raytracing on GTX cards, surprisingly.

The wider support for ray tracing also means we'll likely see greater support from developers, which solves that portion of the chicken an egg conundrum at least.

Battlefield V, Shadow of the Tomb Raider, and Metro Exodus now support real-time ray tracing. For the simple - if not obvious - fact that none of the GeForce GTX series cards has the necessary RT Cores that are present on the RTX cards. All of the tuning for DXR support has presumably been done exclusively on Nvidia GPUs, so how AMD cards would perform in these workloads or with these features enabled is still unknown. With basic reflections on Battlefield V, on the other hand, you'll see 30 fps on the 1080 Ti compared to 68.3 on the 2080 Ti. 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. Star Wars Reflections is a good demo of ambient occlusion, but the company says it also uses a lot of advanced reflections, which makes it more demanding on non-RTX cards. Unhelpfully, all of Nvidia's graphs are for 2560×1440 performance on High or Ultra settings - something they themselves previously warned simply wouldn't be possible on a GTX card when they first announced this actually happening.

The video also breaks down how the graphics card renders images in-game, and Tony Tamasi, VP of technical marketing at Nvidia uses "Metro Exodus" as an example. Here, at 1440p resolution, the GTX 1080 Ti hit a more impressive 50.6 fps, with the GTX 1660 Ti on 36.8fps, naturally considerably behind the RTX cards like the vanilla 2080 which managed 72.8 fps (with DLSS).

This post originally appeared on Tom's Guide. Microsoft used their own fallback layer for a time, but for the public release it was going to be up to GPU manufacturers to provide support, including their own fallback layer. If you want ray tracing with playable frame rates though, only an RTX branded graphics card will be able to pull that off. A couple of hours ago, we informed you about the new driver that allows NVIDIA's Pascal GPUs to run real-time ray tracing effects via the DXR API. Thanks to this new driver there are now "tens of millions of DXR GPUs" in consumer PCs.

While Nvidia coaxed ray tracing into working on non-RTX GPUs with this driver, the experience won't be optimal.

If you're a GTX graphics card owner with a taste for trying ray tracing, an adaptive sync monitor should help significantly.

NVIDIA also highlighted that there are 4 different types of workloads for ray-tracing - ambient occlusion, shadows, reflections, and global illumination.
