Marvel Tōkon’s Open Beta On PC Is A Mess

The open beta for Sony and Arc System Works’ latest fighter, Marvel Tōkon: Fighting Souls, went live on PlayStation 5 and PC yesterday. Early feedback from PS5 players suggests the title is delivering the fast‑paced, tag‑team excitement reminiscent of the classic Marvel vs. Capcom series—once the PlayStation Network hiccups were ironed out.

PC players, however, are encountering a different reality. The Windows version appears to be a heavy drain on CPU resources, leaving many gamers frustrated with the performance they’re experiencing.

Social media and community forums are buzzing with complaints. Hundreds of posts on X and Reddit highlight lag and stutter, often pointing fingers at the “five Sony sub‑services” that launch when the game starts up. These technical snags are becoming a hot topic among the beta’s user base.

While the beta is still in its early stages, it’s crucial to note that the full release is slated for August 6—just under two weeks away.

I ran a series of performance tests on my own machine—equipped with a Ryzen 7 7700X, RTX 4080, and 64 GB of RAM—and, though I’m not a Digital Foundry specialist, I can attest that Marvel Tōkon still struggles even on medium graphics settings.

During gameplay, the title frequently consumed more than 95 % of the CPU and at times drew up to 5 GB of RAM. Additionally, six distinct instances of the PlayStation PC SDK Runtime launched at startup, yet they barely affected CPU or memory usage.

I shared a tweet titled “WHY IS MY COMPUTER TURNING INTO A YOUTUBE POOP” with a link and image.

After allowing the game to run for about half an hour, the performance issues largely subsided, with CPU usage dropping to roughly 60 %. Many speculate this is due to shader compilation during launch, but the fact that the problem recurs on every start rather than just the first suggests a deeper issue.

Even after letting the game run for half an hour, online matches still caused chaos. For some reason, likely due to the anti‑cheat system, the online mode drove CPU usage back up to 90 %. Initially I suspected a connectivity glitch or a cross‑play quirk, but the culprit was the game itself.

I can only hope that, as many tech‑savvy readers suspect, this is a temporary anti‑datamining safeguard on PC; otherwise, I can’t imagine how the developers will resolve these problems before launch.

Tōkon Warriors, we are actively investigating the gameplay and performance complaints currently surfacing on PC.

While our investigation proceeds, we’re sharing community‑recommended troubleshooting steps that may help improve performance…

The developers have taken to X to address the growing frustration among PC players, admitting that the current version of MARVEL Tōkon: Fighting Souls is suffering from gameplay and performance glitches. They confirmed that their team is actively investigating the problems and is already working on a fix, promising to release an update as soon as more information becomes available.

For those eager to jump into Marvel Tōkon on PC at the start of August, it may be prudent to wait until the Steam reviews are published before making a purchase, rather than buying on launch day.
