Directx Error BF4

** TEMPORARY SOLUTION: **

The game has a settings file leak, where it gets slower and slower every time you make a change to any jet keybindings in settings.

To reset it delete the PROFSAVE_profile file in your My Documents/Battleifeld 4/settings directory and start over.

You'll have to rebind all keys again, which also count towards your max # of settings changes.

This is an issue with both jet and helicopter bindings

THIS IS A MAJOR BUG WHICH EA HAS YET TO ACKNOWLEDGE

For those who are PC savvy, here is a regex to find/remove all of the invalid entries in the PROFSAVE_profile file

^GstKeyBinding\.[a-z]+\.Concept.*\.(([4-9][0-9]*)|([0-9][0-9]+))\.[a-z]+ [0-9]+$

My PROFSAVE_profile file had over 327,000 invalid entries in it

So, if you know how to do regex search/replaces, you can bind as many keys as you can until the game crashes, then do a search/remove using the string above, then continue binding your remaining controls. If it locks up again, rinse and repeat until your bindings are all set. I only had to do it once, but YMMV.
