When I play biodefense, or doodle jump the framerate drops so low that its unplayable. I tried restarting and respringint, as well as freeing up memory in sbsettings. I don't know what else to try On more investigation, it seems almost all my apps are suffering. Sonic plays well but other iPhone games don't. I think all the iPad games have low frame rates, as well as the videos I have. What's going on?
