- and Nvidia has unveiled DLSS 3.5, a new version of DLSS that adds 'ray reconstruction' - essentially AI-tuned denoising that boosts the quality of ray tracing effects on RTX graphics cards. The firm also announced a new community remaster of the legendary Half-Life 2, new DLSS 3 and Reflex titles and more.
So far, so standard. Normally these denoisers are hand-tuned, but the innovation is that Nvidia has trained an AI network that can achieve better results. It can use different methods with different ray-traced effects, recognise good pixels and discard bad pixels, and retain the high frequency detail that would normally be smoothed away by upscaling.
As well as improving fidelity, Nvidia says that replacing multiple denoising steps with a single AI-trained model can also lead to a slight performance advantage. They showed an example where Cyberpunk 2077 jumped from ~104 to ~112fps with ray reconstruction enabled. However, in general we should expect performance that's"about the same" with the feature enabled.
