From today onward, you won't need an RTX-specific GPU to see ray-tracing in action, as the latest GeForce driver unlocks DXR support on a wider range of graphics cards. This certainly proves the point that Nvidia is trying to emphasize, ray tracing works better on Turing.
You can download the Nvidia 425.31 Game Ready driver here. While not true in-game benchmarks, they do force GPUs to render ray tracing in real-time. (Our guide to the best graphics cards can help you choose one.) Those GPUs feature dedicated RT cores that accelerate ray tracing, paired with dedicated tensor cores that leverage Nvidia's supercomputers to make games run faster via AI-enhanced supersampling. The drivers, which have always been baked into the DirectX Ray-tracing (DXR) API, will now enable GeForce GTX graphics cards to utilise the feature, albeit on a software level.More news: Khloe Kardashian invites ex Tristan Thompson to daughter's party
At 1920×1080, the GeForce GTX 1080 Ti is capable of maintaining frame rates above 50fps in two of the three titles when running below "Ultra" quality.
In its defense, these benchmarks were run at 2560x1440 resolution with graphics settings set to Ultra. But Nvidia's early discussions of DXR also emphasized that the performance impact of enabling ray tracing was ruinous - heavy enough that only specialty cards like Turing could handle it in the first place.More news: Dutch fertility doctor used own sperm to father at least 49 children
It's a neat video that breaks down the various ray tracing technologies into consumable chunks, including ray-traced ambient occlusion, shadows, real-time reflections, and global illumination. Be warned: All three leverage multiple ray tracing techniques, and Nvidia's numbers show them chugging hard on GTX graphics cards using the same strenuous settings mentioned above.

Here's the data they shared with us, but note that this is obviously created to show how its RTX GPUs are better at this, and is not benchmark charts showing the basic ray tracing they are launching today.More news: Playstation Network: Here’s How To Change The Date Of Birth
Unfortunately, things get worse for GTX cards as we move through the different types of ray tracing and up the complexity. 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. At the very least, you'll be able to see what the effect is like at home, on your own display, before investing in expensive new hardware. On top of that, NVIDIA has also launched a collection of new ray tracing tech demos that anyone with a supported GeForce card can download to get a better sense of what ray tracing adds to a game. I believe that 1080p would be a sweet spot but only for those who want to try the feature to see the difference and to assess whether getting an RTX card is worth it or not. It also released a few RTX tech demos for Atomic Heart, Justice and Relfections.
