Sims 4 crashing unexpectedly

Google AI says today: 

My Q: did maxis crash the sims 4 with their new marketplace causing integrated graphics issue for pcs

AI Answer: While there wasn't a single catastrophic "crash" event for all PC users, the launch of The Sims 4 Marketplace and the accompanying game updates in March 2026 (and previous significant updates in 2024) caused widespread instability, specifically for players using integrated graphics or older hardware.

Key Issues Reported

Marketplace & Mod Conflicts: The introduction of a built-in marketplace for paid custom content reportedly broke over 90% of existing mods. This led to frequent game crashes, "white screen" errors, and broken user interfaces (UI) for players with active mod folders.

DirectX 11 Transition: Maxis transitioned the game to DirectX 11, which significantly improved performance for newer PCs but caused integrated graphics drivers (like Intel Iris or UHD) to fail. Many players on older laptops found the game unplayable unless they manually reverted to DirectX 9.

The "Shopping Cart" Button: A controversial, pulsating "shopping cart" icon added to the UI was cited as a major performance drain on lower-end systems and an accessibility issue.

Recommended Fixes for Graphics Issues

If your game is crashing on a PC with integrated graphics, try these common community-verified steps:

Switch to DirectX 9 Mode: Open your EA App Game Library, click Manage > View Properties, and add -dx9 to the command line box to bypass DX11-related driver failures.

Force High-Performance GPU: If you have a laptop with both integrated and dedicated graphics, use the Windows Graphics Settings to force TS4_x64.exe to use the "High Performance" (Nvidia/AMD) option instead of "Power Saving" (Integrated).

Clear Cache Files: Go to Documents\Electronic Arts\The Sims 4 and delete the localthumbcache.package file to clear temporary data that often causes UI glitches.

Update Intel Drivers: Ensure you have the latest Intel Graphics Driver installed, as older versions are incompatible with the recent engine updates.

Its not you. I also have an i7 more than enough power and 1T to work with and this buffoonery has literally crashed my computer. I pay every month for 24/7 on call IT. Well worth my money. THEY cant even fix what this has triggered in my Iris Integrated graphics. Last night I was able to FINALLY get the Iris upgraded but Sims crash corrupted my graphics files and now I can play but nothing saves. I do not own one mod. Nothing custom other than what I have downloaded directly from the gallery. TALK about p-ode. 

My game has taken to crashing sometimes since yesterday's (March 23rd) update patch. Also buildings keep disappearing from worlds since then. All was perfectly OK before the patch.
