NVIDIA has released the Game Ready Driver 425.31 WHQL which enables ray tracing for GeForce GTX graphics cards - a capability previously reserved for the company's RTX series of graphics cards. This change "enables millions more gamers with GeForce GTX GPUs to experience ray tracing for the first time ever", as the list of DXR-capable graphics cards from NVIDIA has grown considerably as of today.
The list of NVIDIA GPUs that are DXR-capable now includes (in addition to the RTX series):
- GeForce GTX 1660 Ti
- GeForce GTX 1660
- NVIDIA TITAN Xp (2017)
- NVIDIA TITAN X (2016)
- GeForce GTX 1080 Ti
- GeForce GTX 1080
- GeForce GTX 1070 Ti
- GeForce GTX 1070
- GeForce GTX 1060 6GB
- Laptops with equivalent Pascal and Turing-architecture GPUs
NVIDIA previously warned of a performance deficit when comparing even high-end Pascal GPUs such as the GTX 1080 Ti to the Turing-based RTX 20-series GPUs when this driver update was discussed during GTC, and their position is that for the best experience dedicated ray tracing cores will be required, and will make a measurable impact - with or without DLSS (a feature that requires the RT cores of the RTX series of GPUs).
"With dedicated RT cores, GeForce RTX GPUs provide up to 2-3x faster performance in ray-traced games, enabling more effects, higher ray counts, and higher resolutions for the best experience. With this new driver however, GeForce GTX 1060 6GB and higher GPUs can execute ray-tracing instructions on traditional shader cores, giving gamers a taste, albeit at lower RT quality settings and resolutions, of how ray tracing will dramatically change the way games are experienced."
In addition to the driver release which enables the visual goodies associated with real-time ray tracing, NVIDIA has also released a trio of tech demos on GeForce.com which you can freely download to check out ray tracing first hand on GTX and RTX graphics cards. Not only will these demos give you a taste of what you might expect from games that incorporate DXR features, but like any good demo they will help users get a sense of how their system might handle these effects.
The demos released include, via NVIDIA:
Atomic Heart RTX tech demo - Atomic Heart tech demo is a beautifully detailed tech demo from Mundfish that features ray traced reflections and shadows, as well as NVIDIA DLSS technology.
Justice tech demo - Justice tech demo hails from China, and features ray traced reflections, shadows, and NVIDIA DLSS technology. It is the first time that real time ray tracing has been used for caustics.
Reflections tech demo - The Reflections tech demo was created by Epic Games in collaboration with ILMxLAB and NVIDIA. Reflections offers a sneak peek at gaming’s cinematic future with a stunning, witty demo that showcases ray-traced reflections, ray-traced area light shadows, ray-traced ambient occlusion for characters and NVIDIA DLSS technology.
The download page for the tech demos can be found here.
And now to editorialize briefly, I'll point out that one of the aspects of the RTX launch that did not exactly work to NVIDIA's advantage was (obviously) the lack of software to take advantage of their hardware ray tracing capabilities and DLSS, with just a few high-profile titles to date offering support. 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. Looking back to the early days of dedicated 3D accelerators the tech demo has been an integral part of the GPU experience, showcasing new features and providing enthusiasts with a taste of what a hardware upgrade can provide. The more demos showcasing the effects possible with NVIDIA's ray tracing hardware available, the more Pascal GPU owners will have the ability to check out these features on their own systems without making a purchase of any kind, and if they find the effects compelling it just might drive sales of the RTX 20-series in the endless quest for better performance. It really should have been this way from the start, but at least it has been corrected now - to the benefit of the consumer.
