Never had the TOP but, the alarms and simulators the mods now clean up still improved my already nicely performing game. I had only slight lag in IP, the other worlds I have were fine. Now IP has no lag either (except the momentary 3 am hiccup that it should have.)
Yes this is on a gaming rig that' is way over powered for the game but still got IP lag with my immortal sim (same game since release day of the base game) and now, that game flies like a new game - better really. IP quit lagging.
I suspect the Kraken or something else in IP was leaving too many simulators too and, the mods now clean them all up.
