Sims 2 Ultimate Collection Lag

Hello, I posted on here once before, but since then I have gotten a new laptop which fixed my previous problem. However on my new laptop I am experiencing low fps and lag spikes (10-25 fps unpaused and 20-40 fps while paused). I have already tried running the game on low at 800x600 resolution, but the low fps persists. I have also tried using the graphic rules that's provided on here, still low fps. I have also completely removed SecuROM.

I am running Windows 8 bootcamp on my Macbook pro. I think my system is good enough to run Sims 2 on low-medium at least, but please correct me if I'm wrong.

I'd appreciate any help given.
