thanks!..i have the gamebooster but still i have lags/freezes..im gonna try the number 2 and number 4...... lessening vehicles and lots of sims but how can i do that is there any programs that do that..i try clicking the (overwatch) but how can i download that and even the (Register)..how can i do that...thank you for this and im so sorry for being a noob...

ok i tried everything gameboosters,overwatch,fps limiter, register, i even downloaded sunset valley fixed world but luckily it improved a bit, i create a new game it works with just minor freezes,but when i load my savegame..it will have freezes most of the time especially when i rotate the camera and using the ultra fast button,,,,the house is 4 floors from up to down..and i have 7 sims there including pets...can you recommend me some solution on this please...so that sims 3 will run smoothly... thank you and im so soory for asking questions like these im just only a noob i just love this game and i dot want to give up on it..

Well having a house that size, and that many sims would give a lot of games lag. I don't ever have more than 2, maybe 3 floors, and try not to have over 5 sims, including their pets.
So I would recommend trying to play with a smaller family and house/lot, and see if that helps at all.

Hello,

After you applied the Sunset Valley fix, did you clear the caches as the post at modthesims says? http://www.modthesims.info/wiki.php?title=Game%20Help:Sims%203%20Delete%20Cache%20Files

yup! i delete it....i try playing a small family and it runs with only minor of lags(but i can live with that for now).im gonna install world adventures today and download fix worlds. Im hoping that there will be no lags/freezes this time.. il try deleting lots and households in edit town mode and see if it will work...BTW THANK YOU!! FOR REPLYING NOW MY SIMS 3 RUNS WITH ONLY MINOR FREEZES..but if there are mods suggestions programs that will make sims 3 runs more smoothly without this minor lags PLEASE LET ME KNOW IM LOVING THIS GAME but this pesky lags ruining it...
Im gonna install world adventures today im gonna try my luck..

Hello,

AND IM SOOO SORRY FOR BEING A NOOB...

Hello,

The only fix to that problem - as far as I remember from past experience - is just not using that function. Don't ALT+TAB out of the game. You can try playing in windowed mode. Maybe even temporary, until you've done your stuff and then switch back to fullcreen.

ok tenkz ill just switched to windowed mode if im gonna do something then switched back to fullscreen..and THANK YOU!!!!NOW I CAN PLAY SIMS 3 SMOOTHLY to bad i can add WA it will lag if im gonna add that expansion..
