Sims 1 Rerelease lag

So far, the only issue I'm having with the game this far is lag. It's not a lot, and primarily affected live mode after several minutes of playing. CAS and B&B were fine, no issues there. I only had the one Sim, in the Vanilla House, and it was day 2 of living there (technically day one if you click on the funds to see how many days they've lived in their house) when things starting visibly taking a couple seconds longer than they should.
