Just adding my "complaint" to the small list which has probably been seen in general discussion. Since Steam promotes Spiral Knights, I lag far more than I used to, I simply notice it. Maybe it would be interesting in the future to increase the amount of game hosts or upgrade the current one. And in case someone might ask, my computer is able to run SK perfectly, and I already follow all the advices given on WIKI to reduce lag, like I always did; its just that the lag increased since the day I mentionned.
OOO, I'm sure, is working on optimizing things. They aren't a giant company, so it takes some time for things to happen. Patience is going to be key in this situation.
