Hi Orangesaft77 if not done yet try this to help get FPS up with Direct x . If you want my steps to rule out windows making the issue let me know and I will post them. I hope this helps you.
Run the game as Administrator:
Go to the Origin games folder (C:\Program Files (x86)\Origin Games\Battlefield 4) and find Bf4.exe. Right click it and go to PROPERTIES, then COMPATIBILITY and check the box next to RUN THIS PROGRAM AS ADMINISTRATOR.
Do the same with BF4_x86.exe as well.
Run Origin as Administrator:
Go to C:\Program Files (x86)\Origin and right click on Origin.exe and go to properties. Then go to compatibility tab and check the box next to RUN AS ADMIN.
Disable Origin in game:
In Origin - Application settings - Origin in Game - disable Origin in game
===============================================================
Origin Cloud Storage turn it off
Origin, settings, General
==========================================================
In game video settings turn off weapon DOF if off try on
============================================================
If this still fails to fix it you could try this
BF4 folder in my documents holds game configs and screen shots even if BF4 is installed on different drive. When you uninstall BF4 it does NOT remove this folder. So when you install the game again you can still have the same issues.
1- Go to my Documents and remove BF4 folder place it on your Desktop or trash.
2- Be warned you do have to set up your in game settings again.
3-Repair BF4
4- When done go test your game.
