NVIDIA’s Deep Learning Supersampling (DLSS) is a technology native to RTX cards which, through the power of onboard AI, can intelligently increase the resolution of rendered frames in games. DLSS is actually now available for VR, and we’re just starting to see more games support the performance-boosting tech—namely, the Stalker-inspired survival shooter Into the Radius VR (2020).

DLSS is a feature available on RTX 20/30-series GPUs, but must be included by individual developers. Now about six months after the release of the DLSS 2.1 update, which included support for VR headsets, developers CM Games took a step as one of the first to include support for the technology.

Granted, Into The Radius isn’t the absolute first VR game (or rather, VR-supported game) to adopt DLSS. Only two months after DLSS 2.1 released with VR support, battle simulator War Thunder (2013) announced it had enabled DLSS as well, however users found mixed results when playing the game in VR.

What does DLSS do exactly? Road to VR’s Ben Lang describes it best in his initial reporting on DLSS for VR:

The goal is to achieve the same resolution and level of detail as a natively rendered frame of the same resolution, and to do the whole thing more efficiently. Doing so means more graphical processing power is available for other things like better lighting, textures, or simply increasing the framerate overall.

For instance, a game with support for DLSS may render its native frame at 1,920 × 1,080 and then use DLSS to up-res the frame to 3,840 × 2,160. In many cases this is faster and preserves a nearly identical level of detail compared to natively rendering the frame at 3,840 × 2,160 in the first place.

If you’re looking for something more visual, War Thunder released a side-by-side comparison of how the game looks with DLSS toggled on and off. This is of course a flatscreen comparison, but the basic concept is the same.

We’re hoping to see more PC VR games support DLSS, however the global shortage of 30-series cards, and 20-series cards only providing meager performance increases over the 10-series in traditional rendering cases, may have made it too niche for a majority of developers to spend time on.

Do you know of any other VR games which have included DLSS? Let us know in the comments below!
