NVIDIA brings ray tracing to some GeForce GTX cards today

NVIDIA brings ray tracing to some GeForce GTX cards today

You can download the new GeForce Game Ready drivers with DXR support on Pascal-based graphics cards right here.

Nvidia's decision to allow users of the GTX series to experience the Ray-Tracing technology and not limiting it to the RTX GPUs is a step forward. However, besides the GTX 1660 TI and GTX 1660, these cards are built on Nvidia's last-gen Pascal architecture, which means the 10-series cards will need to use their CUDA cores to chew through ray-tracing calculations.

All AAA games with ray tracing use different methods.

In Battlefield V, for example (above, click to enlarge), the GTX 1660 Ti is actually neck-and-neck with the GTX 1080, as is the GTX 1660 with the GTX 1070.

Nvidia explains ray tracing in a video released Thursday, just in time for a new driver for GeForce GTX GPUs and new demos demonstrating the technology, according to a press release.

In terms of compatibility, this new driver supports DXR on the TITAN XP, TITAN X, GTX 1080Ti, GTX 1080, GTX 1070Ti, GTX 1070, GTX 1060 (6GB), GTX 1660Ti, GTX 1660 and the TITAN V. As a result, lighter DXR games will naturally work better with lower-end GTX graphics cards, and heavier DXR games will likely be completely unplayable. Long baked into the DXR specification itself - which is designed encourage ray tracing hardware development while also allowing it to be implemented via traditional compute shaders - the addition of DXR support in cards without hardware support for it is a small but important step in the deployment of the API and its underlying technology. As such, Nvidia says GeForce GTX gamers should expect to run ray tracing at Low quality, perhaps paired with a reduction in other graphics effects, and probably at 1080p resolution. The Turing architecture is advanced and provides more room for ray tracing as it can execute floating point and integer instructions at the same time.

You can also note that the only card that was able to deliver over 30 FPS at 1440p in a single title, Shadow of The Tomb Raider, was the GTX 1080 Ti which averaged around 34 FPS. The performance will naturally be better on Nvidia's RTX line of GPUs. DLSS requires Nvidia's Tensor cores, which are not present on the GTX 10 or GTX 16 GPUs. You can also pick up the latest Game Ready driver here, or by checking GeForce Experience if you have it installed. These cards also come with all new branding to reflect the change: RTX. So in Battlefield 5 uses the Reflections method, the authors' Shadow of the Tomb Raider applied the Shadows method, while the developers Metro Exodus made a symbiosis between global illumination and background shading.

Graphics processing unit making company Nvidia released its line of GPUs which come with Ray-Tracing technology back in August past year.
