Why my Sims 4 is so slow while the computer is not at full load?
I have a big family (8 Sims) in a large home with thousands of objects. Now, my game is extremely laggy and slow. I need to wait half a minute to switch Sims and about 10 seconds to select an object to pop out an option bubble.
In order to figure out the bottleneck, I kept monitoring my computer when playing the game. But I was surprised that my computer was not under max load at all when gaming:
RAM capacity: 32GB, but only around 15GB used
CPU: 8 cores. I understand only 2 cores were used by the Sims 4, but even the 2 cores were not at full load, running at around 70%
VRAM capacity: dedicated 8GB, but only around 6.5GB used; Shared video RAM: sometimes 1 GB, sometimes 0.1GB
GPU: running at around 67%
Temperature: CPU was around 65 Celsius degree, GPU was around 56 Celsius degree
The drivers are all up-to-date
The game was running under 4K with DirectX 11.
I don't use any CC, and I installed all DLCs.
The game version: 1.107.151.1020 DX11
The game ran smoothly when I switched to another family without thousands of objects. But I have played the big family for years, and I don't want to start over with a new family. Can someone please give me hints on the potential bottleneck for the game? Explain why my Sims 4 is running so slow while the computer is not at full load?
