Arc System Works Scrambles to Fix Marvel Tōkon Before August Launch as Beta Crumbles on PC

Marvel Tōkon: Fighting Souls, the upcoming tag-team fighter from Guilty Gear developer Arc System Works, is facing a rocky road to its August 6th PC release after a troubled open beta weekend revealed a string of platform-specific problems. Players on PC have flooded social media and Reddit with complaints ranging from severe frame rate drops to unresponsive input buffering, painting a concerning picture for a game now just days away from its full commercial launch.

At the center of the criticism is what players describe as dangerously poor CPU optimization. Community analysis on Reddit suggests the game hammers a single CPU thread — a problem reportedly tied to anti-cheat software and the PS5-centric architecture the port appears to be built around. Players have also flagged the presence of five Sony sub-services running continuously in the background during gameplay, adding unnecessary load and drawing unfavorable comparisons to notoriously troubled PC ports of the past.

Input handling has emerged as a separate but equally serious concern. One player conducted hands-on testing and reported that input buffering is 'virtually nonexistent,' making it difficult to execute combo chains reliably. Directional motion inputs for special moves are being misread or outright dropped, which is a particularly damaging flaw for a fighting game where frame-precise execution is fundamental to the experience. For competitive players, this alone could render the game unplayable at a high level.

The mandatory PlayStation Network sign-in requirement is adding further friction. Players report being forced to sign in every time they close and relaunch the game, a recurring complaint that has dogged Sony-published PC titles for years. Combined with the fact that the game is already blocked in over 100 countries due to this same PSN linking policy, the requirement is doing real damage to goodwill heading into launch week.

Arc System Works acknowledged the situation over the weekend, issuing a public apology and confirming the team is actively investigating. The studio shared a series of community-suggested troubleshooting steps — including enabling the 'execute shader warmup' setting in graphics options — though it was careful to note these are not officially confirmed fixes. With the full release less than two weeks away at time of writing, the window for meaningful technical corrections is narrow, and player confidence in the port's day-one readiness appears shaky at best.
