BF4 PC KEY BINDING PROBLEMS

This is a problem with the file:

<DRIVE>:\USERS\<USERNAME>\My Documents\Battlefield 4\Settings\PROFSAVE_profile

It's getting too large for BF4 to process because BF4 is writing thousands of duplicate copies of each key binding to the file, making it 100's of thousands of lines long.

Edit this file (I used excel because I'm familiar with it)  and look for lines like the one below:

GstKeyBinding.default.ConceptSpectatorSquadDown.1.axis 24

Remove any lines that contain a middle number greater than 2.. There will be thousands of them, so you'll need to find an automated way to do it.

I brought the file in to Excel as a "." delimited file, wrote a formula that put a "remove" string in to a cell if the middle number was greater than 2, then sorted on that cell and deleted everything that contained the word "remove" on the line, then strung it all back together and pasted it in to a text file, then replaced the original PROFSAVE_Profile with my newly minted de-duped one.. Works fine

You'll have to do this every time you change your key bindings, so get them right and then leave them alone.
