~ How old is your Gaming rig?as I had a NVidia GTX 750 three PC's ago, I now have my own built PC, & my card is NVidia GTX 2080 , I was having graphic issues with my NVidia 1070, (my last PC) but that was mainly due to my CPU being not strong enough to run the Video card properly!!( the CPU & Mother board were over 7 years old & needed upgrading! The Video card was only 4 years old)
~ I have every game for the Sims 4, so it is only natural for things to get laggy, though in the Sims 4 they just tend to not show, I was helping Simmers on a FB Sims page with PC & Gaming problems, (#SAA) so going by what they experienced (though I have not experienced lag in the Sims 4, just graphics getting blurry, & my eyes don't need that!) the lag happened to me in the Sims 3 ( I had to upgrade three times to handle the load of all the EX & SP & store content, in fact my NV GTX 750 was what I came into the Sims 4 with)
~ So maybe look at what you need to run what you have installed & if in doubt get in contact with EA Help/EA Answers as they will tell you straight out what is needed for what games you have installed, I am so sorry I could not help you with this but going to the people whom know the game as they built it will be faster! (& also if the CC or Mesh is HQ, it needs a high end PC with a High end Graphics card to make them show properly,( also a heads up they are very high in Polies & with just a few of those HQ meshes/CC in your PC will impact your game performance! So avoid them if at all possible till you upgrade your PC! Not saying yours are, but just in case they are they do impact game play if your PC can not handle them!)
