@AlanCray Did you already try to make a new game cfg as your old one could be blocking it if not give this a try as well as try a clean boot to be sure a program is not making a issue. As well as your video card is only mid range so it will not pull off the FPS a high end card in BF4, As well as this issue is from win 10 update from the sounds of it. So your best bet if all this fails to help is set everything to low in game for now and keep off all this in game as stated in my first post :] ....
In game video settings right side set to custom and set everything to LOW but last three turn them off ....
1-antialiasing deferred off
2-antialiasing post off
3-ambient occlusion off
on left side be sure vertical sync is off also set resolution scale to under 100 like 80 or 90 this will up you FPS
Try a clean boot : run a Clean Boot: https://support.microsoft.com/en-ca/kb/929135 >This should ensure that no programs are interfering in the background.
Below are programs known to make issues in BF4
Disable Mantle if you have it and try Direct X, Turn OFF Anti-Aliasing Deferred in video card settings in game. If you have page file turned off then turn it back on as this can make errors even with 32gigs ram.
Others have said if they uninstall MSI Afterburner issues / crashing is stopped. So if you have this installed remove program and test BF4. Also look at other programs as Asus Game First Service...ROG Game First , Razer synapse, Razer Cortex, Qualcomm Killer Service , Fraps, EVGA Precision, Geforce experience, be sure to turn off the streaming function that is enabled by default ,Raptr, RivaTuner , ASRock eXtreme Tuner, Steam, Skype, aero ,Overwolf extra program in teamspeak and xfire are known to make issues as well. And I am sure more programs not in my list yet turn one off at a time and test BF4.
Uninstall the HD Audio Driver from the video card driver install add/remove programs. This silly thing makes issues in BF4 for some. Reboot then repair BF4 to be safe.
If all this fails to fix it then try this...
C:\Users\your PC Name\Documents\Battlefield 4
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. Even if its not a new install it is still worth trying as the game cfg could be mucked up.
1- Go to my Documents and remove BF4 folder place it on your Desktop for now.
2- Be warned you do have to set up your in game settings again.
3-Repair BF4
4- When done go test your game. If it fails reboot your PC and run repair game again and test BF4.
