I was recently promoted to Commander, until then the game ran like a dream, nice and smooth. After the promotion I started having so much lag STO is unplayable sometimes. Its mostly on the ground, but still effects space battle.
I didn't get out of the game after my promotion, but from then on the lag was horrible, I cleared some chaches, did a norton cleanup (usually cleans up my computer) but no change. My bandwidth has not changed, its usually steady around 5mbs.
