Marvel Tōkon: Fighting Souls PC Port — Every Major Problem, Community Fix, and Why the Steam Rating Is So Low

• Persistent micro-stuttering and frame pacing failure: The game's built-in FPS limiter introduces recurring frame timing spikes roughly every 30 frames, causing judder even on high-end hardware. Players report getting only 45 FPS on systems that easily run other demanding titles like Tekken 8 and Street Fighter 6 .
• Abnormally high CPU usage: During the open beta (July 24-26, 2026), the engine was found to pin CPU cores unnecessarily. The day-one patch partially addressed this, but many players still report excessive CPU load .
• Shader compilation stutter on load: The game forces unnecessary shader recompilation cycles at startup and during matches unless the shader warm-up option is manually enabled .
• Easy Anti-Cheat blocking Linux/Steam Deck: The kernel-level anti-cheat prevents the game from launching on SteamOS, Proton, or any Linux environment, locking out a significant portion of PC players entirely .
• Mandatory PSN login with performance overhead: The required PlayStation Network overlay reportedly tanks performance on PC, and repeated sign-in friction is widely reported .
• Launch failures and black screens: Some players cannot get the game to boot at all, with no error messaging. The anti-cheat component has been reported to open into a black window, pinning the CPU for up to half an hour before the game loads .
• Region lockout: The game is unavailable for purchase or launch in 132 countries on Steam due to Sony's PSN account requirement, repeating the exact controversy from the Helldivers 2 launch in 2024 .

The 58–59 FPS Cap and Riva Tuner Workaround

One of the most widely reported issues is the framerate getting stuck at 58–59 FPS, even on powerful hardware. The culprit appears to be a conflict between the game's native 60 FPS lock and certain background software. The most widely recommended fix is to disable the in-game FPS limiter and use an external tool, such as RivaTuner Statistics Server (RTSS), to cap the frame rate at a clean 60 FPS. The game's own limiter is the source of the frame-timing spikes roughly every 30 frames .

Additionally, some users on the Steam Community report that simply disabling antivirus software like Malwarebytes immediately resolved the cap, restoring a steady 60 FPS in menus and matches .

The Epic Games Store Background Theory

A widely circulated community "fix" — reported by Polygon from Discord chatter — claims that running the Epic Games Store launcher in the background, even if you own the game on Steam, improves performance. The theory is that since Marvel Tōkon runs on Unreal Engine 5 and communicates with Epic's backend services, having the launcher active resolves some frame-pacing issue. Polygon notes this is one of the more difficult-to-believe suggestions, and results are reportedly inconsistent .

Other Community-Suggested Fixes

The community has compiled a long checklist of workarounds, none of which work for everyone :

• Enable Shader Warm-Up at launch and wait for it to complete before matchmaking.
• Disable Frame Generation (DLSS 3 FG causes frame-time spikes).
• Switch to exclusive fullscreen (borderless windowed adds input latency).
• Disable the NVIDIA App overlay and any other GPU overlay software.
• Pause or close OBS, Discord, or any screen-capture/streaming software during play.
• Disable the PSN overlay if possible via Steam launch options (unconfirmed).
• Lower graphics settings — though many high-end users report the same stutter regardless of settings.

Multiplayer and Competitive Impact: One-Sided Rollback and Crossplay Chaos

The PC issues do not stay on PC. The broken performance directly impacts online multiplayer, creating a nightmare for both PC and PS5 players .

• One-sided rollback: When a PC player's frame rate drops, the rollback netcode becomes asymmetric. The PC player experiences a delay of up to ~8 frames while their PS5 opponent sees a normal match. PS5 players are effectively punished by queueing with PC users .
• PS5 players disabling crossplay: In response to the one-sided rollback and general instability, PS5 players are actively disabling crossplay in their settings to avoid matching with PC opponents, further fragmenting the player base that crossplay was supposed to unite .
• Tournament ban on PC: Just two days after launch, the major weekly fighting game tournament Tampa Never Sleeps cancelled its PC bracket outright, moving all competition to PS5 because the PC version was deemed too unstable for competitive play .
• Prominent streamers switching to console: FGC icon MaximilianDood uninstalled the PC version live on stream, calling it "really sh*t" and "too frustrating," declaring he would play only the PS5 version going forward . Other fighting game content creators have publicly followed suit.

Developer Response and Patch Status

Arc System Works issued a formal apology during the open beta weekend and promised a slate of day-one improvements, including reduced CPU usage, frame rate fixes, shader compilation improvements, OBS/Discord compatibility fixes, and rollback netcode updates . However, the day-one patch did not resolve the core issues — the same stuttering, frame cap, and rollback problems persisted at launch . As of August 9, 2026, neither Arc System Works nor Sony has announced a dedicated post-launch PC performance patch. The developers have acknowledged ongoing investigation but have not committed to a timeline .

Steam Rating: A Disastrous Reception

The game launched to a "Mixed" rating on Steam, a disastrous reception for a high-profile Sony-published fighting game. Early counts showed roughly 40% positive out of 617 reviews (60% negative) . PC Gamer reported around 56% negative out of nearly 1,600 reviews on launch day . Later reporting from August 7 showed 43% positive (488 positive, 647 negative out of 1,135 reviews) . The rating has fluctuated between roughly 40% and 44% positive.
