For a competitive fighting game, inconsistent frame rates and delayed controls are more than launch-week inconveniences: they can determine whether a match feels fair. That is why the PC problems in Marvel Tōkon: Fighting Souls’ July 24-26 open beta matter more than a routine pre-release bug list.
Arc System Works apologized after the three-day PC beta was hit by poor performance, stuttering, instability during sessions, and control responsiveness problems. The developer acknowledged the disruption and said it is working on fixes before the full game arrives on PC and PlayStation 5 on August 6.
Performance is the largest concern because it affects every part of the game: training mode, local play, and online matches. Frame-rate drops can make timing unreliable, while stutter can disrupt combos, defensive reactions, and the fast team-based exchanges that define the game’s Marvel roster.

Players also encountered input buffering and motion-recognition complaints. Those issues may require more than a simple stability patch, since they affect how commands feel and how reliably special moves trigger. In a game built around explosive abilities such as Phoenix Cyclops’ Optic Blasts and Phoenix Force-powered attacks, controls need to be consistent at match speed.
Separate anti-cheat and authentication problems created a more direct barrier for some PC users. Anti-cheat-related behavior could affect performance or prevent a smooth startup, while PlayStation Network login prompts on reopening the beta complicated access for others. These are configuration-specific problems, but they can stop a player from reaching online play at all.

Before buying at launch, PC players should verify that post-beta updates address stutter, controller or keyboard input recognition, anti-cheat startup, and PSN sign-in behavior; if any remain unresolved, waiting for the first technical patch is the practical choice.
