Invisible Objects
Certain objects have become invisible. "Mortimer's Secret" bookcase, and the left end version of the cottage living upper cabinet are invisible, regardless of game mode. however, they do become visible in outside lighting, and can be highlighted and interacted with. (Also, the bookcase's glass detail and shadows remain.) Mods are disabled, I've repaired the game, and I've deleted caches.
@Hotchar Please remove the -dx11 command line argument and instead force Sims 4 to use the Nvidia graphics card. Right-click the desktop, select the Nvidia Control Panel, click Manage 3D Settings > Global settings, and choose the high-performance Nvidia processor. If this works, in that the game is in DX11 mode—you can check the version in the lower-right corner of the Main Menu—it's fine to try forcing the Nvidia GPU only in Program settings, for TS4_x64 and TS4_Launcher_x64. But please do try global settings first, as I've heard from a few people who say the program settings didn't apply.
Let me know what's still invisible, if anything, and whether your problem looks like this known issue:
Please also make sure you haven't enabled laptop mode in the graphics settings; it would be in the lower-right corner, below post processing and uncompressed sim textures.
