FPS drops to 15 whenever I'm in autopilot.
This only happens on Steam, not on the normal download. I didn't have this problem when I first updated to beta 4, I only started having it after playing a few (2 to 4) new games on Permadeath difficulty.
On a related note (still only Steam), each time I died on the first few games, the game crashed shortly after I returned to the main menu. The crashing seems to have stopped, but I think the autopilot lag started as soon as the game stopped crashing. See http://ministry.kronosaur.com/record.hexm?id=96419
EDIT: This issue disappeared when I started playing again on 23 Jul, but after another crash after dying, this issue has returned upon restarting the game.
Setting VideoQuality to Minimum resulted in no autopilot lag, but game crashed after dying. I set the VideoQuality to Standard and got autopilot lag again, then after a few games returned to Minimum, but still experience autopilot lag.
