Marvel Tokon: Fighting Souls has launched with a badly performing Windows PC port, leaving players to try unconventional and largely unverified workarounds to reduce stuttering and frame drops. The game's Steam reviews have dropped to a 40% approval rating, with most negative feedback centred on technical performance rather than the game itself, and the problems are severe enough that some competitive players and tournaments are abandoning the PC version altogether.

Suggested fixes range from running the Epic Games Store in the background even when playing via Steam, to capping the framerate at exactly 59.9fps using third-party software Riva Tuner Statistics Server, though players report mixed results and it is unclear whether these actually help or act as placebos. Compounding matters, the game's netcode means one player's technical issues can worsen a match for their opponent even on a well-running PC, a phenomenon known as "one-sided rollback." Streamer Maximilian Dood switched to playing on PS5 mid-stream, the Tampa Never Sleeps tournament series has banned Windows PC players from its brackets, and some PS5 players are disabling crossplay entirely to avoid affected opponents.
