Many laptops now come equipped with two graphics cards-- an integrated card by Intel (which is weaker and used for everyday tasks such as web browsing and word processing) and a dedicated graphics card by Nvidia or AMD. The Sims 4, like the Sims 3, defaults to the integrated card, which causes poorer graphics and can cause some glitches (deformed baby). Here is a walkthrough for how to set your game to run using the Nvidia card.@ceejay402
has kindly provided instructions for AMD cards in the second post!
Step one: Right click on the desktop and select NVIDIA Control Panel.
Step 2: Once the program opens, select Manage 3D Settings
Step 3: Next, click on Program Settings
Step 4: Click on Add
Step 5: In the pop-up, select The Sims 4 and click Add Selected Program.
Step 6: Click on the dropdown next to the number 2. and select High-Performance NVIDIA Processor
Step 7: Click on Apply.
Step 8: Click on Desktop and then make sure that Display GPU Activity Icon in the Notification Center
Step 9: Look at the bottom right screen of the taskbar. You should see a new icon there that is a black and gray square. You may need to click the little arrow to the left of the icons to find this icon. When the game is running, the icon will be colored as in the screenshot.
To confirm that everything worked, run the game. When it is up, you can click the square icon and you should see The Sims 4 listed as a program using the Nvidia GPU.
I hope this helps! Feel free to ask questions.
