Arc System Works identified two critical audio-system bugs that caused frame rates to drop below 60 FPS on high-end PCs for Marvel Tōkon: Fighting Souls, which launched on August 6. A patch of approximately 10 GB was released on August 10, improving the game's Steam approval rating from around 39% to approximately 46% by August 11. The PC version faced severe stuttering and input lag, leading to negative reviews, while the PS5 version received acclaim. The patch addressed three main issues: a CPU-heavy startup routine, an unnecessary audio-processing task during matches, and a polling loop for audio input devices. Players were advised to accept a shader warm-up prompt on first launch to ensure optimal performance. Despite the improvements, issues like the PSN account requirement and Linux compatibility remain unresolved.
