this might be a long shot considering i don't even have the game on pc but there might be a small chance that there is an option to not play cutscenes and that the pc version has it turned on. is all i can help you with sorry
I've looked, there is no such setting, thanks for trying though.
So while it was on sale on Steam I bought and installed SFIV:AE and when I play arcade mode no matter who I choose I don't get to see their intro or ending, I verified my steam install just to make sure all files were there. Anyone else have this issue?
