Possible fix for Performance / crashing related issues battlefield

[ZeroDamage]

If you are overclocking your system, remove the overclocks and go back to stock. It doesn't matter how long you've been overclocking your system, it is probably the problem. My game kept crashing and stuttering in game and everything. Once I disabled my overclocks, my game started playing great. I was even able to re-enable ultra-high and what not on my system without a hitch.

I think it's partly due to how much system resources this game requires. Even if you had a stable system, Battlefield 3 will push it to it's hardest like other games haven't, so people's overclocks might not be as stable as they thought.
