Previous discussions on this topic indicate that higher end machines can and do install everything at once, and have no such limitations on the size of the resulting dbc's. The problem you're describing is the result of the limitations of your hardware (and, to a lesser degree, to a badly coded Launcher, which nevertheless works alright if your computer does not suck).
As for stuff not showing up in-game, sounds like you've got PEBKAC gumming up the decrapification process.
I think my machine is more than enough to handle The Sims 3.
My specs:
i7 2600
GTX 590
8G ram
Intel 510 SSD
Windows 7 x64
I've asked other people using the same content pack as mine. They seem to be fine. If you mean there's PEBKAC does that mean I should decrapify all the sims3pack by myself again?
Thanks.
Yeah, of course it can "handle" TS3. Read conversations between members here, however, and it is obvious that your specs play a major role in how well the Launcher functions. My computer's specs exceed those of your own in several respects and it still can't handle Launcher installations as well as some better machines can; ask Witch. The Launcher is shit and simply does not work as well as you seem to think it "should" unless you've got a really good machine.
And yeah, there's a reason why you're not supposed to download decrapified files. I don't *think* decrapifying them again will help if they were already decrapified using an outdated s3rc (correct me if I'm wrong, someone). Just download the raw files like everyone else. If we're misinterpreting and you *did* start with raw files, then PEBKAC still stands as the most likely issue. Make sure you're using the proper tools, and using them correctly. The instructions are right there.
