BF4 has encountered an error and needs to close - all of a sudden?!

Thanks to a community post, I've finally solved this issue. It's not down to my hardware or my software config. It's down to the fact that after however many months of gameplay it's been decided that I can't use MSAA any more and have had to find a way to reconfigure my gfx settings outside of the game (because you can't even do something that simple without the game being live and stable).
And this suggestion wasn't made by EA or a clever dev. it was discovered by a community member with time and patience.
FYI it was 'DiamondLightning' who stuck it in small words so I could get to the bottom of the issue quickly.
Looks like the community outdoes EA on every level once again.

Thanks Community members!

For those people coming here looking for a fix - atidxx64.dll had an error caused by BF4. (I'm running ATI cards). The issue is MSAA (or so I've read). I fixed mine easily by using AMD Gaming Evolved software (RAPTR) as it has a game gfx optimiser - using this I was able to disable MSAA and other graphics options outisde of the game without modding files or uninstalling anything. As my cards are low-level now I simply reset the graphics to "performance" and this immediately cured the problem as it removed MSAA among other things.
Hope this helps someone in future.
