The beta testing of Marvel Tokon: Fighting Souls on PS5 has been mostly smooth, with minor connectivity issues, while the PC version has faced significant performance complaints from players. Arc System Works has acknowledged these challenges and is investigating them, providing troubleshooting steps such as warming up shaders, disabling frame generation, and turning off anti-cheat features. There are speculations about Sony's involvement in background operations related to the game, but these claims lack concrete evidence. The official launch is approaching, and optimization work for the PC version is necessary, although feedback for the PS5 version remains positive.
