Support for Steam on Linux NVIDIA DLSS Comes to Select Windows Games

0

Valve has long tried to get game developers and publishers to see Linux as a serious, profitable gaming platform, and not just because it likes the open source operating system. He basically wants the games to be free from Windows and Microsoft development frameworks and eventually to be available on his own Linux-based Steam operating system. Steam OS and Steam Machines have largely failed, but Valve still seems to be pushing for Linux support for Windows games and its latest attempt is to make NVIDIA’s sophisticated DLSS technology work on some of these titles.

Short for Deep Learning Super Sampling, DLSS is NVIDIA’s marketing term for oversampling which involves AI and machine learning to optimize the process. In a nutshell, machine learning determines which parts of a picture frame are of most interest to gamers and, therefore, should be oversampled rather than applying it to the whole frame and all at once. real. The result, at least in theory, is faster frame rates that don’t noticeably degrade the graphics.

Of course, NVIDIA DLSS is proprietary technology specifically designed for Windows. The odds of NVIDIA making it natively available on Linux are almost nil, which is why Valve is taking a different route. It works with NVIDIA to make DLSS work through Steam Photon, Valve’s modified version of the popular WINE software that allows Windows programs to run on Linux and some Unix-like operating systems.

While that sounds like great news, there are a few captures that almost make it look like a chimera. As Ars Technica notes, there are less than 60 games that support NVIDIA DLSS on Windows and even fewer of these work well on Linux through Steam Photon.

And there is the situation where NVIDIA does not have as many fans and users on Linux compared to AMD due to the quality of its graphics drivers. The AMD version of DLSS called FidelityFX Super Resolution was also recently announced and ironically it even works on NVIDIA cards that don’t support DLSS. Of course, there is still no hard evidence of this technology in practice, and it’s likely AMD won’t bother making it available on Linux either.
