@etaaa_5 There are a number of reasons why installing a new OS might cause Sims 4 to lag, but the timing could be a coincidence as well. Just as a test, please start a new save and let me know whether it lags. Please continue to test with no mods or custom content present.
Please also run a dxdiag and attach it to a post.

I tried doing your tips and nothing changed, I'm so sad about this thing.
@etaaa_5 Please provide a dxdiag, as I mentioned earlier. This is not a troubleshooting step but rather a type of system report I can read to look for errors and other problems.
Here's the dxdiag file
