Ok I've found the problem. It's the notification panel, once you clear it, you won't have lag in the buy mode
I've tried this tonight with no luck.
So far, going to the Map / Travel clears the lag up for me.
I also have No Mods, using a Rog Strix Scar 17 & was surprised I even have this issue when entering Build Buy Mode.
Still would love to play ECO but it sounds like too much hassle! Such a pity and waste of money and I'm running it on an imac! A mac was supposed to answer all my prayers. It's made life worse! I can't even be a musician anymore let alone play a game!
