Hi, I'm trying to co-op behind enemy lines with a friend. I have two PCs with archlinux for the purpose, but the game doesn't run very smooth at all. It's playable, but trying to react quickly tends to be impossible as the mouse kinda lags and e.g. right-clicking to put away your weapon doesn't always register if you do it too quickly. There seems to be a little delay in just about every order you issue. Have you people found any ways to improve the performance?

Also, can I somehow see the mission objectives in multiplayer game? The missions don't start with the briefing that you get in single player, and clicking the corner of the map doesn't make it open up for me...
