After the game loads right at the start, if I press Shift tab to bring the Reactor overlay and then select Chat and close that window, the game dramatically slows down and gets really jerky, from the movement of my cursor to the sound. If I press chat again I noticed there was an error.
ERROR: Closing Link

I took a screen shot and erased my IP, if for any reason you need this IP I could PM to a SD dev, just let me know. Another thing I just remembered, this doesnt happen after I load a game, I get the error but the game doesnt slow down.
