Marvel Tōkon: Fighting Souls launched with substantial technical issues on PC, with players reporting frame stuttering, matchmaking failures, and excessive CPU load during its opening week. The problems prompted the community to investigate solutions independently whilst awaiting an official response from the developer.

Players uncovered several workarounds with mixed success rates, including enabling the game's automatic graphics configuration instead of manual settings, using external tools like RivaTuner or Nvidia Control Panel to enforce stable 60 FPS frame rates, and in one unusual case, running the Epic Game Store in the background. Arc System Works responded by announcing PC performance improvements would release the same day, offering the prospect of both developer-led fixes and community-sourced solutions addressing the launch instability.
