For future games Vulcan might be used, or DX12 or something else, we will all know more about that when it's announced. BF4 is over 2 years old now, you should not expect any new graphics API's being supported.

Thanks (Carbonic)

Mental was really a good API for me as I'm using a 144Hz display. but I guess it's all over unstill Vulcan APi comes on BF1 :D

eny solution on how to get bf4 stop lagg or hugg whatever it called (hack) 

on a 144Hz display?

For your Mantle issue try deleting the Mantle cache file located at:

C:\\Users\\<your pc>\\Documents\\Battlefield 4\\cache 

Also make sure Origin and the game is started as administrator.

I have now tried and one thing that semse to work like 70% other 20%game stop responing or stop working.

1, make Administration on BF4 and Origin.

2. Regedit change the word Battlefiled 4 TM to just Battlefield 4.

3. delete cache where Mental is being operative

    C:/User/documents/battlefield 4/cache

4. get in to the game settings change the Fullscreen from 1 to 0. while you at it change OverallGraphicsQuality to 3 or 4.

5. luanch the game and you will get more chance of getting inside the game starting Mental API.

if it stop working delete Cache file again and try one more 

this is what I did and it somehow works
