I had exited out of the game earlier today to avoid the screen saver error and when I went to start the game back up I got the message that the game was already running. Pulled up task manager and saw that LH was currently using 29.2% of my CPU and over a gig of ram. Okay I thought, maybe the game is just syncing to Steam, I'll let it run for a while. 45 minutes later it's still using 28.5% of my CPU and 891 megs of ram.
