Staring at the plumbob. It spins. It glows. You read the same tip about "moving objects" for the thousandth time, and suddenly, you realize you've been sitting there for five minutes. If you play The Sims 4, the Sims 4 loading screen isn't just a transition; it’s a lifestyle. Sometimes it’s a quick five-second breather. Other times, it’s a grueling test of patience that makes you want to Alt+F4 and go outside.
Honestly, the loading experience in this game is a bit of a paradox. Back in 2014, when the game launched, the return of loading screens was a huge controversy. We came from the "open world" of The Sims 3 where you could watch your Sim bike across town in real-time. Then, Maxis gave us a "closed" environment. The trade-off was supposed to be performance. But as the DLC list grew—reaching over 80 packs by 2026—the weight of that code started dragging those screens down again.
Why the Sims 4 Loading Screen Hits a Wall
It’s rarely just one thing. Most players blame their computer, but even a high-end rig with a 4090 and 64GB of RAM can get stuck in a loading loop. Why? Because the game engine, which is over a decade old at this point, struggles with "bloat."
Every time you hit a Sims 4 loading screen, the game is doing a massive inventory check. It’s looking at your save file. It’s checking every piece of Custom Content (CC) you’ve installed. It’s calculating the relationships of every NPC in the world. If you have a legacy save that’s been running for ten generations, that file is massive. The game has to process all those dead ancestors and their complex family trees before it lets you into the Goth manor.
Then there's the "simulation lag" issue. Sometimes the loading screen doesn't finish because the game is stuck trying to figure out where a specific Sim is supposed to be standing. If you've ever had a screen go on for ten minutes only to find your Sim standing in the middle of a sidewalk three blocks away, that’s the culprit.
The Mod Factor
Let's talk about mods. We love them. We need them. But your 50GB "Mods" folder is the primary reason your Sims 4 loading screen feels like an eternity.
When the game starts or transitions between lots, it has to "index" every single package file. If you have thousands of individual hair recolors or tiny decor items, the game reads them one by one. Professional modders like TwistedMexi—who is basically a hero in the community for tools like Better BuildBuy—often point out that Script Mods (like MC Command Center) are usually faster to load than thousands of loose .package files. This is because script mods execute code, while 3D assets require heavy lifting from the GPU and drive.
Ways to Actually Speed Things Up
You don't need a new PC. Well, maybe you do, but try these first.
First, the "localthumbcache.package" file. Delete it. Now. It’s located in your Documents/Electronic Arts/The Sims 4 folder. This file stores temporary data and images of your gallery and items. Over time, it gets corrupted or just unnecessarily huge. Deleting it is totally safe; the game just generates a fresh, clean one the next time you boot up. It's the "turn it off and on again" of the Sims world.
- Merge your CC. This is a pro move. Use a tool like Sims 4 Studio to merge 50 individual shirt files into one single package. The game handles one large file much faster than 50 small ones.
- Clear the Notifications. Believe it or not, having hundreds of unread wall notifications in your save can slow down transitions.
- The "Save As" Trick. Never just hit "Save." Use "Save As" and create a new file. This prevents the "Save Scaling" bug where a single file keeps growing in size due to overwritten data fragments.
Hardware Realities
If you are still running The Sims 4 on a mechanical Hard Drive (HDD), I’m sorry, but you’re fighting a losing battle. The jump from an HDD to a Solid State Drive (SSD) is the single biggest improvement you can make. We’re talking about cutting a two-minute Sims 4 loading screen down to 15 seconds. In 2026, NVMe M.2 drives are cheap enough that there's really no reason to play on an old spinning disk.
Beyond the Wait: Customizing the Vibe
Did you know you can change how the screen looks? Since the 2019 "rebrand" that gave us the bright blue UI, many players have complained about eye strain. It’s bright. It’s loud. It’s... a lot.
The modding community has created hundreds of "Loading Screen Overrides." You can swap the clinical blue for a soft pink, a dark mode, or even a nostalgic Sims 2-style background. These mods don't usually affect loading times—unless the image file is massive—but they make the wait a lot more pleasant. Some creators even use "Ghibli-style" landscapes or screenshots of the various worlds like Henford-on-Bagley. It changes the psychology of the wait. Instead of staring at a spinning plumbob, you’re looking at art.

When the Screen Never Ends (Infinite Loading)
We’ve all been there. The music keeps playing, the tips keep cycling, but the lot never loads. This is the "Infinite Loading Screen."
Usually, this happens because of a broken mod after a game update. Whenever EA drops a patch, things break. If you're stuck, the "50/50 method" is your only hope. Take half your mods out. Try to load. If it works, the problem is in the other half. Keep dividing until you find the broken file. It’s tedious. It’s boring. But it works.
Also, check your "Tray" folder. This is where your saved households and lots live. If you’ve downloaded a house from the Gallery that used "MoveObjects" excessively or has "corrupted" items, it can hang the loading process indefinitely because the game engine can't figure out where to place the objects.
Practical Steps to Optimize Your Game Today
If you want to spend more time playing and less time scrolling on your phone while the screen loads, follow these specific steps.
- Check your Mods folder for "Deep Folders." The game struggles to read mods that are buried more than one sub-folder deep (e.g., Mods/Clothes/Summer/Shirts is too deep for script mods). Keep it simple.
- Disable "Show at Startup" for the Sims 4 Gallery. This stops the game from trying to connect to the internet and fetch community data the second you open the app.
- Run the "Repair" tool in the EA App. Sometimes files just get wonky. A repair check compares your local files to the master versions on the server and replaces anything that’s been corrupted.
- Limit your "Pack" usage. This sounds painful, but if you have a lower-end laptop, try disabling packs you don't use. There are "Sims 4 Mod Configurator" tools that let you toggle packs on and off without uninstalling them. Do you really need Bust the Dust and My Wedding Stories active if you're just doing a Rags to Riches run in the desert? Probably not.
The Sims 4 loading screen is a technical necessity, but it shouldn't be a barrier. By managing your cache files and keeping your CC organized, you can keep the transitions snappy. Keep your save files "lean" by occasionally deleting unplayed households and clearing out the inventory of Sims you aren't currently playing. These small maintenance tasks add up to a much smoother experience.
