The 'new era' of Rainbow Six Siege means you're going to need some newer hardware if you want to play
Announced in February, Rainbow Six Siege X makes some major changes to Ubisoft's venerable team-based shooter, including a move to free-to-play (kind of) and its first permanent mode in a decade. And yes, with 10 years under the bridge it also comes to the table with some new and rather more demanding hardware requirements.
Rainbow Six Siege X isn't quite a sequel, although it is somewhat confusingly described as an "update to the existing game, to a new game"—joining the ambiguous ranks of Overwatch 2 and Hunt: Showdown 1896.
