Marvel Tokon: Fighting Souls, Arc System Works' new tag fighter, launched last week to starkly different receptions depending on platform: PlayStation 5 players have had a smooth experience, while PC players struggled with poor optimisation, low frame rates and stability problems. On Monday, Arc System Works released a patch aimed at fixing these issues, and many PC players are now reporting that the game finally runs as intended.

The patch reduces CPU usage by fixing high startup load and unnecessary periodic audio checks, addresses sudden frame-rate drops caused by constant audio-input scanning, and corrects frame rate issues tied to certain resolutions. It also fixes bugs affecting battle customisation settings and unresponsive buttons in online lobby mini-games, and improves automatic graphics-quality detection. PC players are advised to re-warm shaders after installing the update for smoother performance. Separately, Polygon's review notes the game itself, a 4v4 tag fighter featuring 20 Marvel characters with more planned, feels sluggish in its core combat despite the improved technical performance.
