Analysis — Phantasy Star Online 2 on the Steam Machine

CPU vs GPU

MMOs get CPU-bound exactly where it matters: crowded hubs and raids with dozens of players drawing at once. Cutting the visible-player limit or character detail helps there far more than dropping resolution.

Community check

ProtonDB is more cautious than Valve's Deck Unsupported rating: 207 reports average Silver (runs with minor issues), so expect to read a fix or two before it's smooth.

On the couch

Steam lists only partial controller support — some menus or modes may still want a mouse, and Steam Input's community layouts are the first thing to try.
