Hello!

I recently reinstalled Sims 3 and got some of the nraas package (Overwatch, Traffic, Register, Tempest, Story Progression, Error Trap, Autosave) together with the smooth mod.

But the simulation lag is absolutely awful. Its best in the early morning right after a reset. But rather quickly the game slows to a crawl, sims start stuttering, speed 3 is completely unusable. I've tried to set the settings I have read about are performant(like removing leaves, traffic delta to -500, story progression to snail pace, wild animals to 0, no limos and force taxis) yet every day the lag gets worse and worse up until the reset.


Overwatch warns me about an increasing number of vehicles being deleted every day, 20000, 30000, 40000. Not sure if that's the cause but felt relevant to mention.

Does anyone have an idea how I could resolve this?

What happens if you remove the Smooth Patch?

Have you made sure your game is on the same patch level as the current NRaas mods are made for? That would be 1.67 or 1.69.

I have the origin / ea version, which is 1.70 I think? Most downloads list 1.69 as the latest and thats what I grabbed.

Do you have a Mac? If so, the Smooth Patch doesn't work, or at least there wasn't a Mac version the last time I checked. And yes, all mods, at least the ones you install the normal way, work equally well (or don't work) on both patches 1.69 and 1.70.

The overspawning of vehicles can definitely be a significant part of the issue here, or perhaps the entire issue. Try using Traffic to disable performance limos, the biggest offender here. Click on City Hall and select:

NRaas > Traffic > Routing > Allow Performance Career Limos > False

Let us know how much that helps with overall performance. If you're still seeing issues, please list the full specs of your Mac: everything under About This Mac except for the serial number... that is, if you do have a Mac. Please also list the packs you've installed and the world(s) you're playing in.

Not playing on a mac. As I said limos are disabled. Packs: all of them.

The city is Barnacle Bay.

I also tried disabling food trucks and icecream trucks and that didn't help either.

After installing...some pack, I can't remember which because I bought them a few at a time, but after that, I had to get Nona's No Limos mod to keep the limos cleared out, even though I had limos turned off in Traffic. Prior to that I had maybe 10 cars being removed each night, but it suddenly rose to several thousand like what you are seeing, and after installing Nona's mod it went back down to maybe one or two a night.

Not sure if this will help with your lagging issue, but it might be worth a shot.

That reduced the daily vehicle purge to 10-20. Thank you so much! The lag isn't completely gone but the difference is night and day.

There is also a bug with the Tour Bus from the Music Career that could also be causing the issue.

I too am seeing tens of thousands of vehicles in the cleanup log. What I don't understand is how this many vehicle records can manifest in such a small place and in such a short amount of time.

Equally confusing is that the only Limo's I've seen are those that my Sim uses. I guess it couldn't hurt to try that Limo fix mod for the sake of ruling that out. I haven't touched any of those other settings that relate to vehicles either. That is probably the next port of call.

Thanks to the contributors for all the handy dandy information.
