nvidia graphic card
Regardless of which card you are using, your game should work - so step 1, we'll get it working for the Intel.
Lagging and Crashing
OK I'm thinking even with your 4 cores, you still don't have a huge CPU, so I'd take off the CPU count limiter - when you have 2 you are limiting your CPU to 1.9 MHz. Which is what is going to be causing you to lag and crash.
Securerom is going to be causing some of your lagging. There is a remove securom tool, that with your noCD Hack will ensure that it doesn't come back and that will sort out some things.
Removing Securom and adding a No CD Hack
You've got 2917Mb texture memory, so it isn't lack of texture memory that is causing the pink flashing.
Pink Flashing is caused by a texture memory leak. It is what happens when you have loaded too many textures in texture memory, and the ones that pink flash, are the ones that have been overwritten. In a perfect world, the program would have been written to reload those textures back into Texture memory, but Sims 2 wasn't. Hence the flashing.
So the way to deal with that is two-fold:
check for texture bloat - how big are your thumbnail files (in the folder My Documents/EA/The Sims 2/Thumbnails) if they are larger than about 40-50M for all but CAS (which shouldn't sit at higher than 100M) then you need to regenerate your thumbnails.
You do that by deleting the contents of your thumbnail folder, then going into game and going through the catalogs in buy mode and build mode - all pages.
Also - how much CC have you in game? It's not so much the amount of CC, as the amount of large textures which can cause the game to have problems with texture memory. So for example if you have a gazillion beddings, try cutting it down to 50 or less. There's a tutorial here about how to default replace your bedding textures as well, which means that 50CC + 37EA beddings is still a great range.
You don't need to weed out all your CC, just reduce the recolours that use a texture 512x512 or greater.
So I removed Securom (didn't know that was an issue with Windows 8.1 too), however after I used the Securum removal tool and wanted to use the TrashReg, it didn't find any lincense info. Is it possible that the removal tool removed that too already?
I also stopped limiting the CPUs, however my config-log file still tells me it's only 1.9 I've got the feeling that lags got a bit better, especially in neighborhoodview (the cars run a bit smoother), however not much.
I deleted the thumbnail folder and loaded the game. As soon as I was on the lot, I got the pink flashing (usually it just happens after some playing). It crashed soon after, so I loaded the game again and it was fine this time. I clicked through the cataloge as you said. I didn't have time to play that long yesterday, but I played for some hours today. I did get some pink textures on Sims, but none on objects and the textures on Sims also vanished when I reloaded the lot. So I guess it helped? I also noticed the thumnail folder is much smaller now.
I have a bit over 8 GB in my game and I'm pretty sure I have a lot of 1024x1024 textures. I know a lot of my own textures are that large and also some of other creators I download a lot from. Not so much beddings (altough I guess I should go through them too), but simply objects. Is there a way to batch-reduce them? Or can I force the game to use a smaller version of the textures (they all have multiple LODs)? Also, does it make a difference that many of the objects are slaved?
Well, the bad news is that it's only recognising 2 CPU - which is the 1.9 which is not enough to run Sims 2 in high resolution. Unfortunately because Sims 2 is an old game and was made before there were quad and octo cores there's not a lot I can do to make it recognise more.
So unfortunately that means that you'll need to lower your cpu usage to make it lag less.
That means we'll need to turn some things off.
Events, PiP, etc.
