Arc System Works has released a performance-focused patch for Marvel Tokon: Fighting Souls following a brief maintenance window. The update aims to resolve major technical issues on PC that have impacted the game's launch, despite its strong reception on PlayStation 5.

While PS5 players experienced a generally smooth release, PC players reported significant frame rate drops, lag, and high CPU usage. These technical problems, combined with mandatory PSN account requirements and a lack of Linux-based platform support, led to a wave of negative reviews on Steam.

The new PC-centric patch addresses several root causes of performance degradation:

- Reduced CPU Usage: Fixes high CPU load occurring during startup and reduces system strain caused by periodic audio processing during matches.- Performance Drop Resolution: Eliminates frame drops caused by the game repeatedly checking for available audio inputs during gameplay.Resolution Frame Rates: Resolves frame rate drops tied to specific screen resolutions.
Alongside direct performance fixes, the patch prompts PC players to run a shader warm-up sequence upon launching the updated build. The auto-graphics quality feature has also been adjusted to select visual profiles that better match a player's system specifications.
Additionally, the update resolves cross-platform bugs affecting settings and lobbies:

- Battle Settings: Fixes an issue where custom colors and items would reset to default upon restarting the game.- Online Lobby: Resolves unresponsive button inputs during mini-game events when action icons were toggled on.- Early feedback from PC players indicates noticeable improvements in smoothness and stability.

The technical fixes may encourage PS5 players to re-enable cross-play after many previously turned it off to avoid performance-related match instability.
