im guessing were having the same problems...lol. its so bad I could change my camera angel in space even when i somehow managed to lock on to a target .
On ground i tap the left (A) or right (D) buttons and swing around over 160 degrees which is making movement virtually impossible.
I have reciently discovered that if i play the whole game in "windowed mode" instead of "full screen mode" that i get CONSIDERABLY less lag. It doesn't eliminate the lag issue but at least it makes the game playable until Cryptic corrects this lag issue.
I hope that help the rest of ya'all who are having severe lag problems like me.
