As I've been saying since the game was in beta: They have no idea how to develop PC games.

There are currently over 150,000 files in the game directory. A standard hard drive, no matter how defragmented, CANNOT LOAD THAT EFFICIENTLY, EVER.

If they went the route of any reliable developer (giant pack files) then the stuttering issue (including load times) would be greatly lessened without the need to buy a SSD.

Non-edit: Apparently I was going to post this 3 days ago but never did.
