Re: Help: Cannot run BF4 in x64, but works in x86
@TheMegosh are you using an AMD card?
If using Mantle drivers on AMD and crashing in X64 version then:
Go to C:\Users\Administrator\Documents\Battlefield 4\settings and delete the file "PROFSAVE_profile" (or you could just move it somewhere else on your PC for safekeeping).This will also reset keybindings and graphics settings so you will need to do them again when you launch the game.
