This command can be used to speed up or slow down the pace at which the game runs at - a multiplier of 0.5 would make the game run in slow motion at half the usual rate, a multiplier of 2 would make it run twice as fast.
setglobaltimemultiplier [multiplier]
| Multiplier | The game time multiplier you wish to set, as a decimal. A multiplier of 0.5 would make the game run at 50% speed (slow motion that is half as fast), a multiplier of 2 would make the game run at 200% speed (twice as fast). |
SetGlobalTimeMultiplier 0.25
The above command would make the game run in slow motion. Because the multiplier is 0.25, the game would run a rate 4 times slower than usual.
