Three new RTX/DXR Ray Tracing Demos have been publicly released

One of the biggest complaints that have been levelled at Nvidia's RTX ray tracing has always been its lack of software support. Yes, it's great that the technology is there, but until it is used by a large number of games, it is hard to see ray tracing as a useful hardware feature, especially when every ray tracing enabled game needs a traditional, non-raytraced version of each graphical effect.    

Today, Nvidia has taken two actions which will help bring ray tracing to more PC gamers. First, their latest Geforce 425.31 driver now supports DXR ray tracing on both Pascal and non-RTX Turing series graphics cards, allowing ray traced graphical effects to be used on graphics cards which lack support for ray tracing acceleration. On top of this, Nvidia has worked with developers to publically release three new tech demos which showcase DXR-based ray tracing in action. 

These actions accomplish two things, as first, it allows users to non-RTX hardware to see what Ray Tracing can add to their games and second they have allowed PC gamers to see ray tracing in action over a large amount of new software. Yes, these tech demos will run at very low framerates on non-RTX hardware, but at least it will run and showcase the graphical potential that ray tracing offers. 

The first of Nvidia's three tech demos is their Star Wars "Reflections" demo, which was created using Unreal Engine 4 using Star Wars assets from ILMxLAB. Originally, this demo ran on four Volta V100 graphics cards to run in real-time, now it can run on a single RTX series graphics card in real-time. This demo used both Nvidia RT cores for ray tracing acceleration and Nvidia's DLSS algorithm to accelerate the demo's performance further. 

Next up we have Mundfish's demo for Atomic Hearts, which used Unreal Engine 4 and DXR raytraced shadows and reflections to offer a unique take on USSR-style robotics alongside creepy mannequins and strange creatures. 

This demo uses Nvidia's DLSS technology alongside its ray traced effects to deliver increased performance on RTX series graphics cards.  


Nvidia's third and final tech demo is for Justice, one of China's most popular MMOs. This tech demo uses ray-traced reflections, shadows and caustics to enhance the game's visuals and also utilised DLSS. 

Within this demo, Nvidia's RTX features can be turned on and off using F5, with F8 toggling ray tracing on its own while F9 enables and disables DLSS on compatible systems. 

All of these tech demos are available to download today, with links to each being available on Nvidia's website

Justice crashes my PC whilst loading, literally a hard freeze (no bsod) have to press the reset button ! !

Seeing 48 fps on the Stomr Trooper demo and fps in the 90s for the creepy Atomic Heart..Quote

I'm getting 24fps at 1080p on the Storm trooper reflections demo with my 4790K @4.4Ghz, 16GB 2133Mhz Ram and 1080Ti.

Still downloading the Atomic Heart demo so will update once it's done.

EDIT: Atomic Heart lows of 10fps during the disco ball headed bot and peaks to 58fps with the manequins.Quote

Getting pretty much exactly 24fps as well, [email protected], 3200 CL14 and RTX 2060 at 1440p. Looks gorgeous, but I didn't realise the demo was this short.Quote
