Weird lag in build/buy mode and sometimes in Live Mode too

@JeanVW

ECO very likely includes a massive FPS drop. If a computer is already a little on the slow side, it may have been there earlier. Laptops are naturally a lot slower than desktops and people seem to like them for some reason. My Intel NUC is very new and quite fast. So, removing ECO gave it a much needed speed boost.

I tested this by putting ECO back in and removing Paranormal. I got a speed boost, but not nearly as big as removing ECO.

If you have a computer that's more on the slower side, I'm willing to bet if you disable more packs, it would run better. Some packs will naturally include a bigger game lag than others. ECO's lag is just very large.  I'm willing to bet if you disable Seasons, the game speed would increase a LOT. You would just have to decide which packs you can live without if you seriously want a speed boost.

It makes perfect sense. The Sims 3 was the same way. They released so many packs that the game got so bad, it would barely even run if you had them all. They even designed the game launcher so you could Choose to disable some packs on the fly if you wanted better performance. It got so bad that the game was unplayable unless you disabled half the packs. The Sims 3 had less packs than 4 but it was a bigger problem because Sims 3 was Open World. Every pack included a massive game lag. Sims 4 they removed the Open World so they were able to release more packs before they started effecting performance. But it was bound to happen eventually.

I wouldn't be surprised if a launcher change was coming in a future update before long.
