make sure you have the trainer off and and drop all your settings right down during the fight, this way you'll get the video at the end instead of a blank screen, once the cutscene has played out wait for the savegame and then put your settings back as they were, you may have to repaeat this again a bit later on with mayor quincy sharp
I have had the same issue. While I know the answer is Reverse Remote Batarang, but Batman can't move at all when Talia's taken hostage.
Is this really a performance issue to suggest tuning down video settings? The games runs perfectly fine in speed and responses. Besides, you can't adjust the video setting AT ALL during the game, except you quit and adjust from the Main Menu.
But I'll try and post back. Hope it'll really work. Thanks in advanced.
