P roton, the tool developed by Valve, the company behind the Steam store, has just received a major update. Based on WINE (Wine is Not an Emulator), Proton is a compatibility layer that enables Windows-only games to run in Linux.
With the latest update, Proton now supports Nvidia’s DLSS tech with DX11 and DX12 games. DLSS (Deep Learning Super Sampling) makes it possible for people with Nvidia RTX GPUs to use AI to upscale games with minimal image-quality loss while boosting performance. This will be a big boon to Linux gamers wanting to play graphically intensive games on lower-end kit. You do need a modern Nvidia GPU, however. Support for BattlEye anti-cheat engine will also enable a lot more Windows games to run on Linux. This will be useful for the Steam Deck handheld, which runs a Linux distro, because some of the biggest PC games use anti-cheat tools.
