Marvel Tōkon: Fighting Souls launched today, but PC players are facing issues not seen on PlayStation 5: low FPS and constant stuttering.

What Caused the Problem?

Developer Arc System Works admitted that the PC version struggled with serious performance issues during last month's open beta and promised a day-one patch to address them. However, players continued to report similar problems on Steam at launch. Reddit user DavidsSymphony noted that even on high-end hardware like the RTX 5090 and Ryzen 7 9800X3D, stuttering occurs at the lowest settings and cannot be fixed by users alone.

This is Arc System Works' first title developed in Unreal Engine 5. Their previous games (Guilty Gear Strive, Dragon Ball FighterZ) used Unreal Engine 4, and the engine transition is believed to be a factor in these performance issues.

What Did the Day-One Patch Fix?

The first update mainly focused on improvements for the PC version. According to the patch notes, the main changes include:

Despite these improvements, the overall rating on Steam remained Mixed after the patch, with only 43 percent of players leaving positive feedback.

Steam Deck Players Left Out

Aside from the PC performance issues, Marvel Tōkon does not launch at all on SteamOS or Linux. Possible reasons include the game's anti-cheat system and the requirement for PlayStation PC Overlay. Arc System Works has yet to make an official statement, so Steam Deck owners are advised to wait for official support.

Community Workarounds

Since the patch alone hasn't solved everything, the community has shared temporary solutions they've tried. While we can't guarantee results, these are worth testing:

1. Manually trigger shader warmup in graphics settings to precompile shaders before entering a match.
2. Disable Steam Overlay and background game recording in Steam settings.
3. Turn off Discord overlay, Xbox Game Bar, and monitoring tools like MSI Afterburner.
4. Switch from borderless to full screen mode.
5. Update your graphics card drivers.
6. If you encounter anti-cheat errors, delete the eos_eac_setup folder in the game directory, then verify game files via Steam.

If none of these steps work, try reinstalling the game cleanly as corrupted installation files can also cause stuttering.

DLC Roadmap Already Announced

While performance issues are in the spotlight, Arc System Works has revealed the Season 1 content. The first new character, Phoenix Cyclops, is coming this fall. Inspired by the 2012 Avengers vs. X-Men storyline, this version of Cyclops wields the cosmic power of the Phoenix Force.
