Microsoft has officially announced its intent to move security measures out of the kernel, following the Crowdstrike disaster a few short months ago. The removal of kernel access for security solutions would likely revolutionise running Windows games on the Steam Deck and other Linux systems.
I got battlefield 5 and explicitly rebought it for Steam to play on the Deck. Like a year later they rugpulled Linux support because 2042 has done so badly that they had to start maintaining their old games again.
