Simulation Lag. Get A Better Computer?

I'm a little confused exactly what lag is being referred to here. From personal experience I can say once I upgraded my pc all lag (as in shuddering screen when trying to move around) has been eliminated. And this is with tons upon tons of cc. I can play on a 64x64 3 story cluttered lot with 0 issues. I couldn't with the bad pc.

If you mean the lag that happens where sims stare off into nothing before doing anything you tell them, or stop doing things to stand there then I still have that kind of lag.

But I honestly think most issues people complain about can be solved with a better pc
