The PS5 and Xbox Series X|S versions of Assetto Corsa Competizione now supports cross-platform multiplayer.
Hopping onto online races via “Quick Join” will see matchmaking with cross-play on by default. Public Multiplayer, Competition Servers (which offers hour-long races) and Private Leagues includes cross-play.
However, there are no cross-play parties.
Assetto Corsa Competizione, the official game for the GT World Challenge, has continued to be updated with free content and paid DLC. Expect to see the tracks and cars from the 2024 season, which includes the Nurburgring Nordschleife, coming soon.
