Please attach your Documents/Paradox/EU4/settings.txt. From your Documents/Paradox/EU4/logs/ folder, attach system.log (rename to system.txt to attach). What version # and checksum do you see a/ in the launcher and b/ in the main game menu, when loaded with NO mods active?

Does this happen from the moment you start a new game? Or start OK then get worse?

Note that you can see your actual fps by turning on that feature in Steam.

Try setting

multi_sampling=0
maxanisotropy=0

That aside I see no real problem in there. Clearly the issue is not fps or refresh rate.

One thing interesting though; of your 8gb of system memory, the nVidia takes away 4gb, and the Intel video another 4gb ... ! Presumably not at the same time, but still ...

I don't suppose forcing the game onto the Intel helps? It shouldn't of course , but worth a test run I think.

If so, it doesn't affect everyone with Win10. You could perhaps try running the game in Win7 compatibility mode, to test that theory.

I would say 30 fps is acceptable for a non-real time game, 20 or lower would be an issue though. But since you get the stuttering when fps is at 60, that's not related to your problem anyway.

BTW according to this story

the nVidia driver version you have is buggy. You should go onto the beta, or back to an earlier version.

Do you have the game and your Documents folder both on the same hard disk?

Assuming you now have EU4 installed in a Steam library on your SSD, try this: use Notepad to create a text file called userdir.txt in the folder that eu4.exe is in. In that file place a single dot, save and exit. That makes the game create the user files and gfx cache on that drive, not in C: where documents is.
