7Flower7Child7 I take it the clean boot didn't help? Please try it if you haven't already.
Please also disable Game Mode and Game Bar, both under Windows Settings > Gaming.
If that doesn't help, please open Windows Settings > System > Display > Graphics > Default graphics settings, and if you see "Variable refresh rate" and/or "Optimizations for windowed games," turn both off. I'm not sure what settings you'd see given your GPU, but for other models of Surface laptop, these settings don't always get along well with Sims 4. Those all have Intel processors and graphics chips though, so it may not apply in your case. But it's still an easy test.
i did do the boot thing, I'm not too sure if it did anything but now sims runs as a background process? don't know what i did wrong..
