I've had nothing but problems with lagging to where I can't play the game. Tried all of the suggestions and I thought it was going to work.
Started with my project family. In it I had two sets of heirs and so I thought it might be too much doing two families, even though they are on different saves, they do interconnect.
Moved them out, then decided to return one of my families. Did fine for a while, then it starts to lag HORRIBLY and the icing on the cake just happened. My sim is swimming to build his athletic skills, wife is heading home from work, he starts making weird sounds and I see the sign that he is drowning.
He is beside the ladder for heavens sake, what is wrong? Naturally, it continues the lagging and with his wife coming home and the popup telling of how great a job she did and has gotten a raise, I can't seem to move from her icon to his to get him to climb the ladder.
Even if I could, one second play, next second freeze for five or more real time seconds, one second play, freeze for more real time seconds, one more second play, more time freezing.
By the time it decides to stop the stupid lagging, he has died and there goes my plans for the ending of this story line.
I know I am venting, but still, this is just total stupidity of the constant lagging.
I am going to have to redo my ending, move my widow and her twins out of IP and uninstall it. I'm going to reinstall SEA that I had no problems with, but had to remove so I could play IP. But, still can't play IP.
There is no lagging in my other towns, MV, DV, MF, AS, RV, SV, none of them lag, just IP. I do have problems with WA now, none before IP. Bet they will stop when I uninstall IP.
