FPS drop and Sttuttering

Hi @Marks-Lenin-Mao and welcome to Answers HQ!

I'm sorry but your Intel i3-6098P CPU is a low power CPU with only 2 cores. It's way under the minimum requirements for the game so I'm not surprised that you get FPS drops and stuttering.

You can try closing down all background applications and set sound quality to the lowest setting but I doubt it will help.

BF1 system requirements:

Just five weeks ago, I was playing the game at high settings. I've been playing with this processor for 1 year.

Ok that's kinda amazing if that's indeed your CPU, I guess what you have to ask yourself is what about your computer have changed in those 5 weeks? Does it happen if you play after a proper clean boot?

I haven't uploaded anything to my strange computer for 5 weeks. I don't have a different program. I have Amd drivers, Adobe Flash Player and Intel drivers. 
Could one of the Intel drivers be corrupted? 

Hey, @Marks-Lenin-Mao make sure that all drivers for windows and your drivers are up to date.

Try running a CCleaner to remove old temp files and cache and turn off any overlay programs for example Discord or Nvidia experience.

Let me know if this works or not for you. 🙂

These didn't work. I switched from Windows 10 to Windows 7. No difference between Directx 12 and directx 11. I uploaded the dxdiag file. Can you check?

The same problem exists in battlefield 4. But there is no problem in other games.

And that's the danger playing with hardware that is below the minimum required specs - for a while you might play just fine until a game, windows, or GPU update comes down and suddenly you can no longer play the game.
