Hello again @puzzlezaddict!
Well, I did and guess what?
May 24, 2020 14:54 my time.
Start the game (I've already created a Sim and placed her in the world)
Placed the "Restaurant" that comes with some expansion, takes 5 mins aprox.
After that, I start my game like you said, brand new, no Origin connection, no internet connection and no other program running (I disabled everything disableable)
It took 10 secs for me to hear the "starting music" (you know which one, right?) so yay!
But uh oh... game really started 1:50 mins after the sweet sound of starting music.
Household: 1 Sim. World: San Myshuno. There are 3 Sims outside my apartment. With a fruitcake.
After around a minute into the game:
I have to pause/unpause my Sim to perform given action.
I have to cancel bathing since Sim's hygiene bar is full and she's still playing in the bathtub. I open the calendar so canceling works, otherwise Sim would keep on bathing.
Annoying sound and repetition of Sims' voices.
Flickering screen.
Sim time: 20:28 Real time 15:11
Sim starts reading a book, progress bar stops so I pause/unpause. Ventilator sound.
Needs bar low as to be in red remains green.
I unzoom cam, action bar progresses.
Sim time: 22:39 Real time: 15:15
Needs bar finally had turned yellow (Hunger)
Ventilator noise: progress and needs bars are neither dropping nor filling. Sound stops, bars move.
Sim time: 00:39 Real time: 15:18
Pause/unpause: both bars progress (remember Sim is reading)
Sim time: 01:05 Real time: 15:20
Sim finishes reading.
Sims outside are still outside chatting, eating. Their voices are the ones that get doubled.
Sim time: 03:23 Real time: 15:24
Sim starts walking through walls and objects.
Actions take a few seconds to appear into the action section.
Sim time: 03:44 Sim goes to sleep.
Sim time: 04:46 Sims outside, still outside
Sim time: 06:21 One of them has peed.
Ventilator sound hasn't stopped for a while.
Sim time: 12:34 Real time: 15:37
I zoom in: ventilator sound stops then starts again.
Sim time: 13:18 Real time: 15:38
While sleeping, I told my Sim to go to the bathroom and prepare some food.
Energy bar full, Sim still asleep, after pause, she wakes up.
DURING PAUSE: Bladder bar fills up, 4 simoleons get deducted from my account for the salad she has not even prepared yet. "Physically" my Sim is on her way to the bathroom.
Sim time: 13:48 Real time: 15:40
Audio doubles, image flickers
Sims outside, still outside.
Sim time: 14:36 Real time: 15:43
Sim has gone to the bathroom, washed her hands, prepared a salad, she sits at the table... and she won't eat. Pause/unpause for it to happen.
Sim time: 15:34
She's done eating, though progress bar isn't completed. Pausing fixes this.
Sim time: 15:58 Real time: 15:47
As a favor to outside Sims, I'll take my Sim to the library. Press telephone icon, click travel option...
Sim time: 16:22 Real time: 15:49
Traveling to Willow Creek Archive
Real time: 15:50: Loading screen...
Decent audio
Ventilator sound goes off.
Real time: 15:53 "Starting music" sound
Plumbob stops
Ventilator sound starts
Sim time: 16:06 Real time: 15:54
Sim at the library.
I save and exit.
Sorry for the long post, for short, I experienced a significant decrease in loading screens time, all the rest, still happens at my normal game.
Thank you if you read all that, if not, thank you anyway.
