Default Suggestions/Recommendations for Handling Mods?
Hey all,

I have long loved how creative and amazing the modders for the Sims 3 community are.

Unfortunately, I have now reached a point where I have so many mods that I use for Quality of Life that it's lagging/freezing my game consistently. It makes me sad because even after compacting all my CC, it's really the script/tuning mods that seem to be the issue.

I'm wondering how y'all handle the prospect of having too many mods, or if there's anything I might be missing in how to optimize it further.

To clarify, I'm playing 1.67 on Steam, and I have all expansion packs (except for Katy Perry Sweet Treats).

I've gone up and down the main Steam performance improvement guide, added the smooth patches, installed DXVK, and added Nraas Error Trap and Overwatch to the mix for help. I've tried a lot of different combinations of mods but I always end up either light on the mods I want to play with for performance sake (thus impacting my gameplay enjoyment), or heavy on the mods and also the lag/performance issues.

I guess I'm just feeling kind of sad and worried I may not be able to use more of the amazing mods here on this site, and I wonder how many mods y'all have been able to add before you started seeing issues.

Thank you so much!

I really doubt tuning mods are the issue unless maybe you tuned everything to fire every second? There's just no way "no autonomous ____", "lower wages", etc. could hurt performance. If you don't merge them, they can contribute to slow loading, but I don't think they'd impact performance even then.

The only mod I've ever had problems with was NRaas SP, which was why I got rid. Honestly, I think it's the only (working) mod I've heard people having performance issues with. (Still, lots of people run it fine.)

Are you sure it's general performance and not something broken (or just super laggy)? Like, try some 50/50 testing on a test world, assuming you get these issues in all gameplay and not just long saves or whatever (btw if it's only longer saves, considering you have Overwatch already for the worst, I would be looking at inventories: especially sims, but also chests and fridges).

Also, I'm not 100% sure about this, but I think compressing cc makes gameplay slower - because of the unpacking. It speeds up load times, though. Anyway, I don't do anything about that, and my game runs fine. I don't run all EPs/SPs any more, though. That's mainly for loading times with my cc, but there's some gameplay impact too. But I doubt you want to hear that!

Hey arinabean! Thank you for your reply! I have a few tuning mods, which I don't really think are the big issue. It's mostly the script mods, I think. I have quite a lot of them.... So I'll give the 50/50 testing a go and see what happens. I hadn't thought about the inventories, so that's something I could check too.

Recently, I was trying to play a legacy file on a custom world (it's not very old, I just started it like a week ago, so I ran a save cleaner on it and all that), so I don't think it's the file necessarily. I thought it might be the custom world, so I saved the family to the bin, and put them into Sunset Valley. It seemed okay until I started re-adding my mods. I don't use Nraas Story Progression because it makes my game unplayable. Although, I do run quite a few of the other Nraas mods, which were part of the mods I added back in, so maybe that's part of the issue.

If compressing the CC makes gameplay slower, I definitely don't want to do that! I play everything I have installed, and the biggest factor is the store stuff. So maybe I have to bite the bullet on trimming that stuff down. That will definitely take some time though.

And as for playing without certain EP/SPs, I still appreciate you mentioning it, because at the end of the day, I think I'm more hopeful for a miracle rather than face the truth that this is truly a 32-bit game that can't handle much hahaha

Anywho, thank you for the input!! I'll do some further testing and see if I can optimize any further.
