Aerith - just replied to the same question in Valmars thread amusingly:
Workstation lag is due to the amount of recipes on screen after TFP decided to allow you to view all recipes anywhere.
THE ONLY WAY currently, to solve it, is via less recipes. There may be a way to disable the feature that TFP added...in which case, making a multitude of different workstations to gate recipes would be the only fix.
Type a random series of letters (ex. Dgsjrksy) into your "search" bar to hide all the recipes and nullify all lag for now.
Cheers!
