Mod that makes double speed/ultra speed faster?

I'm pretty sure CyberBob's on MTS is still current even though he hasn't been around for years. His mod (all of the various flavors) only edits one game resource; it's not likely any of the later patches even touched that one thing.

I would never use any of these mods myself. My game already falls all over itself when run on the two high speeds, trying to make it simulate the entire world even faster would only be asking for trouble. I happen to think this kind of mod is much better suited for games that do not have an open world and so many sims to control all at once, even when we are only really focusing on our active household.

Are you talking about like how the sims 4 has super speed when sims are asleep or at work? I don't think I've heard of a mod like that for sims 3.
