Arc System Works has released a performance-focused patch for Marvel Tōkon: Fighting Souls on Steam. The update arrives shortly after players reported significant stability issues, including micro-stuttering and high CPU load, which have persisted since the game's launch on August 6, 2026.
Confirmed Changes
The update implements several technical fixes to address performance bottlenecks on PC:
- CPU Optimization: Multiple changes reduce overall CPU load, specifically addressing high usage during the startup process and additional system strain caused by periodic audio processing during matches.
- Frame Rate Stability: Developers addressed a bug where the game continuously scanned for available audio inputs, a process that frequently triggered sudden performance drops.
- Resolution Fixes: A specific issue causing frame rate degradation when using certain display resolutions has been resolved.
- Settings Persistence: The patch fixes a bug that caused custom colors and items to revert to default settings after restarting the game.
- Lobby Improvements: Buttons that previously became unresponsive during open lobby mini-games when action icons were enabled have been corrected.
- Graphics Detection: Auto-detection for graphics quality has been improved to better align with individual system specifications.
Required Player Actions
Players on Steam should ensure their client has downloaded the latest version. Upon the first launch following the update, the game will prompt you to warm up your shaders. It is recommended that you complete this step to ensure optimal stability and frame pacing while playing.
