For me, The new Metro 2014 crash/freeze sound loop everytime and also Dawnbreaker on certain parts of the maps. Both since Feb 13 patch, except I didnt know about the Metro until i tried to play it on the 19th. Also other maps are fine including the other 2nd Assualt maps.
OVerall I have been fine with the issue but now that it is months later and 2 expansion later, this is now completly unacceptable. By this time the game should be 100% prefect, no excuses for how complicated the engine is or how many consoles and versions there are. If it cant be fixed by now, they over commited and better get it sorted next patch, and never so this for any release od any game after this. And yes I know, if DICE had any say, they would have waited but obvious pressure from EA issnt helping us the consumer.
Ps I have Win8.1 GTX780 i5-4670k as if it helps anymore.
