Battlefield 4 launched in a wonky enough state that disgruntled shareholders have launched a class-action lawsuit over how it effected EA's share price, but bless its heart, developer DICE has been trying. The PC edition has received a new patch today, targeting more of those nasty crashes, and both PlayStation 4 and PS3 versions are being patched tomorrow too.
The PC client patch notes explain that it's fixing several specific crashes and deadlocks, so check them if you've been suffering. It also brings fixes for assorted bugs and "improving general stability," and tweaks balancing of jets a bit.
It was accompanied by a server update fixing five server crashes too.
