Be careful of setting your FOV too high... It messes with your sens and ADS.

At release I had no probs running it on ultra, but after a session yesterday was getting much lower fps and had to drop to high. Any ideas why this might be?
Play for 5 minutes - crash
Try to rejoin - fail
Play for 20 minutes - crash
Think i'll give up on this until some more patches.
I'd change your Origin account password pronto & set up the extra Login Verification in My Account > Security
Do it now and then you should be OK + Virus/Malware the crap out of your PC to be sure.
If someone did use your account then they could have used the MBT LAW from another player/vehicle.
i went from 90 fov in BF3.. because ADS fov was all the same unlike BF4 where i have gone down to 78 anything lower just makes it feel to console like on a 27" monitor
also fov doesn't effect vehicles or 3rd person view like it did in BF3 so lower fov is actually better then higher fov for infantry where as it was the opposite in BF3.
Contact Live Support.
Sounds like someone has access to your account and switched email.
Get the virus/spyware checks running while you do
Since they patched the server's i have found the game a lot more stable i now may only get a server crash a couple of times a day however pc crashing for me happens atleast 5+ times a day (depending on how much i play) atm and is really annoying i dont understand why there has not been a patch since release day for client side it just seems really really slow....
..snip.. also if you are using hotmail consider changing to a better email provider like gmail as my hotmail has been attacked/hacked countless times but my gmail "touch on wood" has never been hacked in the 3 + years i have used it!
