Is that only when using mods? What do you see when all of them are disabled?

In the main game menu ck3.exe uses 2.4gb on my modest rig. At the start of a new game, 3.6gb.

I was only looking at physical memory. To get that many page faults I'd think you might be short of memory overall, perhaps running a lot of other stuff at the same time?

If you exit all other apps before starting the game does that still happen? What size page file do you have? I recommend at least 16gb these days, in some cases up to 64gb.

BTW where is that dialog? It's not one I'm familiar with.

Okay, I recommend at least a 32gb maximum these days, in some cases up to 64gb!
