All the people saying they have it disabled for the sake of faster loading had me really curious as to just "How much" of a difference disabling it makes. I decided to get a stop watch and test loading the same save game with it enabled and disabled. I know I did the same test years ago when this feature was first added, but I couldn't recall the results...and I figured, so many people in this thread can't be wrong...can they?
I timed each one twice, to help eliminate just the random factor:
Enabled:
Load 1: 2 minutes 49 seconds
Load 2: 2 minutes 44 seconds
Disabled:
Load 1: 2 minutes, 45 seconds
Load 2: 2 minutes, 42 seconds
I'm definitely leaving it enabled; a time savings of 2-4 seconds over nearly 3 minutes just doesn't make it worth having absolutely nothing to do while waiting for the game to load. I guess I could read a book or something though.
I think if I wanted the game to load faster, the real time saver would be getting rid of all the CC and store content I use. Not going to happen!
