It was also slow when I didn't have CC, I've removed my CC too and it's still laggy. ChillNana Please remove your entire Sims 4 game folder from DocumentsElectronic Arts you can just place it on your desktop. Going into the gallery is unbearable, the mouse is slow and laggy and pictures won't even load. It used to work fine, but it got all slow and laggy. Someone please help me, I've tried to repair the game, delete all cache, all videos and screenshots, and have even set it to 32 bit. Occasionally it would, but it would come back again, CAS isn't laggy anymore, but gameplay when moving with WASD or turning the camera can be super laggy, if I have a household of 1 it's laggy, if I have a household of 8 it's laggy. I quit the game for a few months, hoping it would go away. SimCity 4 has to perform a lot of calculations and there are usually a lot of items on the screen, hence you might have problems with the game moving along quickly no matter what kind of hardware you’re running. Even CAS was slow and laggy, my mouse was all laggy too. I have tried to run SimCity 4 on three top of the line systems with monster video cards and it still runs slow. I went and created a sim and the game when I bought a house and all that stuff ran really slow. When I first got the Sims 4 it ran perfectly fine and was fast, about 7 months ago, it started acting really slow and laggy, a week or two after I got City Living, I thought that City Living was the problem so I uninstalled my game and didn't let the City Living Expansion download into my game again.
