IVE BEEN GETTING LAGSPIKES WITH THE NEW UPDATES INSTALLED

Okay i've been getting really annoying lagspikes ever since i updated my sims 4. Firstly the game loads a bit slow now and once it starts the lag spikes are already present 
I will get like 70-100 fps for 5 seconds and then after i get up to 20 or something for 1-2 seconds and its very annoying PLS HELP!!

PS: I got a fairly good gaming pc and my sims 4 worked perfectly before the update

The game can get slow when you have outdated Custom Content.

Uhm can you elaborate on outdated Custom Content sir?
and also i tried to rollback my nvidia driver and that solved the problem but after 2 days give the lagspikes went back

Update : I also tried to delete a bunch of useless stuff and the lagspikes went away but after some time it went back  WTF is this

The best way to check is to move your folder [username]\Documents\Electronic Arts\The Sims 4 to your desktop.
You then start a complete new game, no downloads, no unwanted additional stuff.
Still lag, then it must be the specs of your computer.

(You can always move your old The Sims 4 folder from your desktop back to Documents\Electronic Arts)
