Weekly Reminder about mac's fps on ascension

Well weekly whenever ascension is around. The fps rate on ascension for mac players ranges from 10-20 (aka unplayable) for the last about 5 rotations. It never used to be like this and I don't know why it happened. Please at least address the situation as I'd like to be able to play the mode normally without having to disconnect at some point and hope it returns to normal. Thanks.
