@kixxinghae I wouldn't call your laptop incompatible. It's not a bad model, just not really a gaming computer, and its performance reflects that. Its graphics chip is always going to be slower than the dedicated cards that can run the game on high or ultra settings. The graphics chip is the limiting factor; the other components are better, relatively speaking, at least as long as they're performing as expected.
You can't really upgrade it either, other than adding more RAM. But before you go that route, check the Task Manager while playing and see whether you're running out of memory. The graphics chip will borrow some to do its processing, but even then, 8 GB total may be enough for Sims 4. If you are low on free memory though, it might be worth adding more.
Your model has one module soldered in, and one slot for a removable stick. I don't know whether your particular laptop has 8 GB RAM soldered and an empty slot, or 4 GB soldered and a 4 GB stick in the slot; you'd have to open it up to look. But either way, you could put an 8 GB stick in the accessible slot and have either 12 or 16 GB total. Like I said though, make sure memory is a factor before spending money on this.
Ther other thing you could do is try lowering some of the graphics settings. You may want sim detail on very high, but it's possible lowering it to high or medium will improve things enough on its own. It's at least worth trying, to find out whether this setting makes a difference. You can also try quitting and reloading before an event.
If neither of these makes a difference, you can try some hardware monitoring, to make sure the components in your laptop are performing as they should. Let me know if you're interested, and I'll post instructions.
