Re: Sims 3 missing textures+blurry worlds Help
@BrownNy13 Your graphics card should be able to handle 60 fps, or a lot higher, unless you happen to be playing on a 4k monitor. Even at 2k, the card shouldn't have any issues generally running the game at or close to 144 fps. Sims 3 produces framerate drops all by itself, especially on complicated lots (like World Adventures tombs) and in inclement weather (rain, snow, hail), but I'm surprised you'd see anything as low as 39.
On the other hand, custom content can be significantly more demanding than base game items, in particular high-poly cc. So if you use a lot of it, you'll get much lower framerates than in the vanilla game.
More relevantly though, and I meant to mention this last night, if you're playing in a broken or overly complicated world, performance can tank on even the strongest systems because the game engine itself can't keep up with all the data it needs to process. Isla Paradiso is one example of a world that's so broken in its default state it's basically impossible to play properly. There are plenty of similarly broken custom worlds, and some that are made well but are too large or too detailed to run well.
For IP itself, you can play in a fixed version of the world, edit it yourself, or use the pack's features in other worlds. The rest of the content of the pack is completely fine and works in any world where the water is deep enough.
If you want to get a baseline for performance, try running the game in Sunset Valley, Riverview, or Twinbrook. Then compare that with what you're seeing in your existing saves.
