I'd like to add a tip on this that might help others having this issue.
If laptop mode is stuck on. Meaning won't turn off. Move the Options.ini file from the Sms 4 folder to the desktop. - C:\Users\Username\Documents\Electronic Arts\The Sims 4
Launch the game to help create a new one. You will need to reset all options again, but this will help reset laptop mode to off. Which is the default setting.
I came across this tip from Crinrict when she was trying to help someone else with the laptop mode stuck on issue.
“It should work if it's turned on but you might have performance issues if you do that.”
Seriously? You’re saying that we might have performance issues with terrain pain with laptop mode on, like indefinitely? I’ve always used terrain paint and it’s worked fine. My laptop can barely keep up with the game as it is, I absolutely cannot turn off laptop mode.
I don't work or have any association with EA. I give advice to the best of my knowledge and cannot be held responsible for any damage done to your computer/game.
Please only contact me via PM when asked to do so.
