Intense Lag!!

[Minty]

I take it you have patched right up to date? There's some issues with game play caused by the last patch. If you have the likes of Late Night as well there's problems caused by the amount of traffic on the road (especially taxis) in game.

You may wish to consider getting Twallan's Master Controller mod, which amongst others user cleans up events off screen that can make your game lag (such as electronic equipment like TVs and stereos being left on in lots overnight when there's no one watching them - public lots are the pits for this). Even if they're happening off-screen, it will deal with them.

It will also get rid of "homeless Sims" ie. the loads of paparazzi popping up since Late Night, as well as giving you an option to scrub them in game using annihilate.

Many people find Twallan's mods highly effective in running their game more smoothly, you may wish to give these a try. As they are .packages as opposed to Sims3Packs, they are easy to install (drop into your Mods\packages folder, that's it!) and remove as required.
