Metro Exodus update brings DLSS improvements to Nvidia RTX 20-series PCs

Metro Exodus Review

If you happen to own one of Nvidia’s latest RTX series graphics cards and are also struggling with performance problems in Metro Exodus, you’re in for some luck. A February 21 update for the title recently delivered enhancements to Nvidia’s deep learning supersampling (DLSS) feature and other fixes for low-specced PCs.

The first post-launch update — version 1.0.1.1 if you purchased the Epic Store, or version 1.0.0.1 if you purchased Steam — brings fixes and improvements for DLSS to “improve overall sharpness” in the game. It also delivers otherwise undisclosed “RTX fixes and optimizations.” Other than the fixes for Nvidia’s graphics cards, the update introduces general stability improvements, a VFX fix for DX11, and benchmarking tool enhancements.

However, the experience with DLSS is not always perfect. TechRadar notes that while DLSS is now usable, some gamers are reporting that enabling it in the latest Metro Exodus update could also break HDR functionality.  Regardless, it still would come as an improvement. We previously tested DLSS in the game before the patch and it wasn’t exactly perfect. There were blurs on most elements on the screen when DLSS was turned on, including on the guns and in the reflections in the water, so the update brings hope for a much better experience.

As announced at CES 2019, Nvidia’s DLSS technology leverages machine learning to render game visuals without causing performance issues or framerate drops. This is also partly accomplished with artificial intelligence on the tensor core found onboard the new RTX series graphics cards. The core can study a large sample of input frames and render scenes quickly, but Nvidia isn’t very clear on how it works beyond that. Along with Metro Exodus, only a select set of games will support the DLSS feature, including Battlefield V. 

DLSS is not to be confused with ray tracing, which is another hallmark feature of Nvidia. Ray tracing is a separate rendering technique which provides more realistic lighting effects in games. Just like with DLSS, it is only currently supported in Battlefield V. Other titles confirmed to get support for ray tracing in 2019 with future updates includes both Assetto Corsa and Shadow of the Tomb Raider. Several yet to be released games will get it as well, such as Atomic Heart, Enlisted, and Justice.

Nvidia RTX DLSS: everything you need to know
RTX 3090 installed inside a gaming PC.

Nvidia has two standout features on its RTX 30-series and RTX 40-series graphics cards: ray tracing and DLSS. The PlayStation 5 and Xbox Series X have both done a good job of introducing most people to ray tracing, but DLSS is still a little nebulous. It's a little complex, but it lets you play a game at a virtualized higher resolution, maintaining greater detail and higher frame rates without taxing your graphics card as much. It gives you the best of all worlds by harnessing the power of machine learning, and with the introduction of DLSS 3, the technology just got even more powerful.

But there's a little more to the story than that. Here's everything you need to know about DLSS, how it works, and what it can do for your PC games.

Nvidia has shared some happy news today -- the library of games that support DLSS is about to expand. With updates coming to plenty of new titles, there'll be more opportunities to try out DLSS for yourself.

Unfortunately, Nvidia's cutting-edge DLSS 3 tech is still quite elusive. Only six games are confirmed to support DLSS 3 close to the launch of the RTX 4090.

Nvidia's upcoming flagship, the RTX 4090, was tested in Cyberpunk 2077. It did a great job, but the results were far better with DLSS 3 enabled.

The card managed to surprise us in two ways. One, the maximum clock was higher than expected, and two, DLSS 3 actually managed to lower the card's power draw by a considerable amount.
