I'm experiiencing some pretty serious stabiility issues throughout the game. At first, I thought it was connected to a specific mission or two. then I thought it was connected to combat in space, then I realized that it's a random bug that strikes wherever you may be. For that reason I'm thinking that it probably is not graphics related. It hits no matter how low I dial my graphics settings. IIt even hits in sector space.
It is a random total system freeze. It's so bad that it requires a complete hard-restart of the computer. My system is AMD based, not top of the line but well within the pecs for the game. 6Gb RAM, ATI 4670 with Catalyst 10.1, latest updates for Win7 install, AMD X4 620 processor. I've played MMOs before and I've never seen a release candidate this unstable. It's a shame, because this is an enjoyable game otherwise.
It is a major problem, I think, for the sole-sever architecture. With a game this unstable, it causes the game to crash more often because of the large numbers of players.
