When I launch through the launcher, this game starts fine, but in under a minute, I suffer from a severe input lag. This lag extends to all my computer, taking minutes to bring up the task manager. I must kill the explorer even, otherwise my PC freezes. I solved the problem running the executable and not the launcher, but I am curious if I am the only to suffer this (windows 7 x64 ati hd7870) and what does GOGLauncher do for this game.
