Okay, I admit that I am bored. and I'm tired of studying, so I am copy+pasting some contents of the readme file for more info and posts and threads here.

PERFORMANCE TIPS
----------------
When you run The Sims Life Stories for the first time, the game will automatically configure its graphics options based on your machine's specs. If game performance seems sluggish or choppy, there are a few things you can try to improve things:

* Make sure your computer meets the game's system requirements (see threads above). If you do not meet these requirements, the game is unlikely to run acceptably.

* The number of Sims you have on your lot is one of the biggest factors in determining performance. Lots with low numbers of Sims (2 or less) will run more smoothly than lots with many Sims (3+). [you can have Max. of 4 sims on a lot though ]

* In the game, go to the Graphics/Performance Options panel. Reducing or turning off options will improve the game's performance. Reflections, Screen Size, and Smooth Edges are the options that will affect your frame rate the most, followed by Shadows and Lighting.

* Close all other applications while running the game, including anti-virus software which often runs in the background.

* Some large community lots in the game (like the Starlight Cafe) may be slow when scrolling around. Frame rate should pick up considerably when the camera stops moving and you are interacting with the Sims.

* Adding RAM to your system is a very efficient way to improve performance.

* Defragment your hard drive regularly for optimal disk performance (Start>All Programs>Accessories>System Tools>Disk Defragmenter).
