to change time compression settings manually edit
\data\Cfg\Main.cfg
My NYGM game has the following:
[TIME COMPRESSION]
TimeStop=0
RealTime=1
LandProximity=4
CriticalDamage=1
CrewEfficiency=1
AirEnemyDetected=1
SoundEffects=2
CharacterAnim=4
EnemyDetected=8
RadioReport=8
Particles=8
PrayState=8
HunterState=128
3DRender=32
Maximum=4096
You will need to reset both the default file somewhere under sh3.exe and the player's copy of Main.cfg in users\[your username]\...err... somewhere. Sorry I can't be more specific I run the game under Linux
