How many The Sims 3 packs do you play with at the same time?

I play the sims 3 with all packs installed, all store content and all necessary mods at max settings. This game always stuttered for me when running it at 60 fps or more but it is rock solid at 30 locked with nvidia inspector and doesn't stutter or hitch even once. I have no simulation lag either at 30, did get it at 60 though. The sims 4 has simulation lag no matter what and this is on a gaming rig I might add so I stick to sims 3.
