Thanks @puzzlezaddict ! I'll give those a try.
My theory about it being an algorithm that doesn't scale in build mode was wrong btw. I can make the lag inside build mode go away by clicking '...' just like I can make it go away outside of build mode by clicking '...'. That suggests that a state is flipped when transitioning between the two modes causing lag, and hitting '...' unflips it so everything works well again. There is nothing in build mode or live mode that is lagging on its own.
Quick update on my situation.
Bad News:
I enabled the FPS counter in Origin, and it was showing ~7fps ☹️. Using '...' stopped working for me after the latest update.
Good News:
I was able to fix it. I removed everything inside my C:\Users\<user>\Documents\Electronic Arts\The Sims 4\Mods folder (including Resource.cfg), then I started the game, and things ran great. Afterwards, I added all the mods back in one by one (except for the Resource.cfg file, the game had generated a new one for me). No I'm getting a steady ~90-100fps regardless of what I do. I can hop in and out of buy mode and cas with no issue. Not sure what changed, all the mods are the same. Still, worth a shot.
This could also work for people without any mods. Just delete everything in that folder (probably just Resource.cfg) and see what happens. Couldn't hurt right?
For the record. I have every pack installed and active except for Paranormal while getting 90-100fps. Hope this helps someone!
*edit* Bad News Again:
This stopped working as soon as I traveled to another neighborhood. But at least clicking '...' works again.
Eco totally drained my Mac, so had to uninstall. Not missing it at all, as it's incompatible with some of my other packs. How man celebs have turbines all over their cell homes? lol
@GednaaMe too. ECO completely destroys my framerate. I want to investigate how to remove some of the more... laggy... features in a mod without losing some of the assets, furniture, clothes, power generation, etc. Might not be too easy.
ECO adds a LOT of features that makes off-the-grid viable. Without them, it's practically impossible. But it ruins the framerate. If I can turn off those features in a mod without losing the objects, that would be optimal. Otherwise, I'll have to weigh my options.
Ok I've found the problem. It's the notification panel, once you clear it, you won't have lag in the buy mode
You are right Hakhob, I have a fps counter displayed when I play I cleared it and it just jumped from a disgraceful 15fps to 120Fps! then i accidently click gameplay icon, and jumped back to build mode, and i'm back at just 15fps, and now I have no notification board to clear, because It's already empty, now what do i do ?
And if you just click again in the build mode, then click in the panel notification (without clear it). I found that solution for me.
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!
